TransposedMultiRow Class

TransposedMultiRow Class

Extends the FlexGrid control to display data using a transposed layout, where columns represent data items and rows represent item properties. Also this control allows to display each item in multiple columns.

Use the layoutDefinition property to define the layout of the rows used to display each data item.

Please note that the TransposedMultiRow control does not support some FlexGrid properties. These properties are disabled, so changing these properties will have no effect. The list of disabled properties includes the following:

FlexGrid.allowAddNew, FlexGrid.allowDelete, FlexGrid.allowDragging, FlexGrid.allowPinning, FlexGrid.allowSorting, FlexGrid.columnLayout, Column.width, FlexGridFilter, Selector.

    • Optional options: any

      JavaScript object containing initialization data for the control.

    Returns TransposedMultiRow

Properties

activeCell

activeCell: HTMLElement

Gets the HTMLElement that represents the currently active cell element.

If no cell is currently selected, or if the selected cell is not currently within view, this property returns null.

activeEditor

activeEditor: HTMLInputElement

Gets the HTMLInputElement that represents the currently active cell editor.

If no cell is currently being edited, this property returns null.

allowMerging

allowMerging: AllowMerging

Gets or sets which parts of the grid provide cell merging.

The default value for this property is AllowMerging.None for the FlexGrid control and AllowMerging.All for the PivotGrid control.

This property does not apply to the MultiRow control.

allowResizing

allowResizing: AllowResizing

Gets or sets a value that determines whether users may resize rows and/or columns with the mouse.

If resizing is enabled, users can resize columns by dragging the right edge of column header cells, or rows by dragging the bottom edge of row header cells.

Users may also double-click the edge of the header cells to automatically resize rows and columns to fit their content. The auto-size behavior can be customized using the autoSizeMode property.

The default value for this property is AllowResizing.Columns.

alternatingRowStep

alternatingRowStep: number

Gets or sets a value that determines the number of regular rows between 'alternating' rows.

The default value for this property is 1 for the FlexGrid. Set it to zero to disable alternating rows, or to a number greater than one to insert multiple regular rows between alternating rows.

The default value for this property is 1 for the FlexGrid control and 0 for the PivotGrid control.

anchorCursor

anchorCursor: boolean

Gets or sets a value that determines whether extending selections with the mouse or keyboard should change the start (cursor) or the end of the current selection.

The default value for this property is false, which causes the grid to move the cursor and keep the selection end anchored.

Setting this property to true causes the grid to move the selection end and keep the cursor anchored. This is Excel's behavior.

ariaLabel

ariaLabel: string

Gets or sets the aria label property of cells host.

autoClipboard

autoClipboard: boolean

Gets or sets a value that determines whether the grid should handle clipboard shortcuts.

The clipboard shortcuts are as follows:

ctrl+C, ctrl+Ins
Copy grid selection to clipboard.
ctrl+V, shift+Ins
Paste clipboard text to grid selection.

Only visible rows and columns are included in clipboard operations.

Read-only cells are not affected by paste operations.

The default value for this property is true.

autoGenerateColumns

autoGenerateColumns: boolean

Gets or sets a value that determines whether the grid should generate columns automatically based on the itemsSource.

The column generation depends on the itemsSource property containing at least one item. This data item is inspected and a column is created and bound to each property that contains a primitive value (number, string, Boolean, or Date).

Properties set to null do not generate columns, because the grid would have no way of guessing the appropriate type. In this type of scenario, you should set the autoGenerateColumns property to false and create the columns explicitly. For example:

import { FlexGrid } from '@mescius/wijmo.grid';
let grid = new FlexGrid('#theGrid', {
  autoGenerateColumns: false, // data items may contain null values
  columns: [                  // so define columns explicitly
    { binding: 'name', header: 'Name', dataType: 'String' },
    { binding: 'amount', header: 'Amount', dataType: 'Number' },
    { binding: 'date', header: 'Date', dataType: 'Date' },
    { binding: 'active', header: 'Active', dataType: 'Boolean' }
  ],
  itemsSource: customers
});

The default value for this property is true for the FlexGrid control and false for the PivotGrid control.

autoRowHeights

autoRowHeights: boolean

Gets or sets a value that determines whether the grid should automatically resize the rows when the data or grid layout change.

This property is especially useful when the grid has columns configured to word-wrap their content (see Column.wordWrap), and when the grid has a relatively small number of rows (auto-sizing is an expensive operation).

The default value for this property is false.

autoScroll

autoScroll: boolean

Gets or sets a value that determines whether the grid should automatically scroll its contents while users drag rows or columns into new positions.

Row and column dragging are controlled by the allowDragging property.

The default value for this property is true.

autoSearch

autoSearch: boolean

Gets or sets a value that determines whether the grid should search for cells as the users types into read-only cells.

The search happens on the column that is currently selected, if it is not editable. The search starts at the currently selected row and is case-insensitive.

See also the caseSensitiveSearch property.

The default value for this property is false.

autoSizeMode

autoSizeMode: AutoSizeMode

Gets or sets which cells should be taken into account when auto-sizing a row or column.

This property controls what happens when users double-click the edge of a column header.

By default, the grid will automatically set the column width based on the content of the header and data cells in the column. This property allows you to change that to include only the headers or only the data.

The default value for this property is AutoSizeMode.Both.

bigCheckboxes

bigCheckboxes: boolean

Gets or sets a value that determines whether the checkboxes used to edit boolean columns should extend to cover the whole cell width.

Big checkboxes are easier to toggle with the mouse, since the user may click anywhere in the cell to toggle them.

The default value for this property is false.

bottomLeftCells

bottomLeftCells: GridPanel

Gets the GridPanel that contains the bottom left cells.

The bottomLeftCells panel appears below the row headers, to the left of the columnFooters panel.

caseSensitiveSearch

caseSensitiveSearch: boolean

Gets or sets a value that determines whether searches performed while the user types should case-sensitive.

The searches include searching for regular text (see the autoSearch property) as well as searching for items while editing data-mapped cells (see the Column.dataMap property).

The default value for this property is false (searches are not case-sensitive by default).

cellFactory

cellFactory: CellFactory

Gets or sets the CellFactory that creates and updates cells for this grid.

cells

cells: GridPanel

Gets the GridPanel that contains the data cells.

childItemsPath

childItemsPath: string | string[] | null

Gets or sets the name of the property (or properties) used to generate child rows in hierarchical grids.

Set this property to a string to specify the name of the property that contains an item's child items (e.g. childItemsPath = 'items';).

If items at different levels have child items with different names, set this property to an array containing the names of the properties that contain child items et each level (e.g. childItemsPath = ['checks','earnings'];).

Example

The default value for this property is null.

This property does not apply to the MultiRow control.

clientSize

clientSize: Size

Gets the client size of the control (control size minus headers and scrollbars).

cloneFrozenCells

cloneFrozenCells: boolean | null

Gets or sets a value that determines whether the FlexGrid should clone frozen cells and show then in a separate element to reduce flicker while scrolling.

The default value for this property is null, which causes the grid to select the best setting depending on the browser.

collectionView

collectionView: ICollectionView<T>

Gets the ICollectionView that contains the grid data.

If the itemsSource property was set to an ICollectionView, this property returns that value.

If the itemsSource property was set to an array of data items, this property returns the internal CollectionView created by the grid to support currency, editing, and sorting.

columnFooters

columnFooters: GridPanel

Gets the GridPanel that contains the column footer cells.

The columnFooters panel appears below the grid cells, to the right of the bottomLeftCells panel. It can be used to display summary information below the grid data.

The example below shows how you can add a row to the columnFooters panel to display summary data for columns that have the Column.aggregate property set:

function addFooterRow(flex) {

  // create a GroupRow to show aggregates
  let row = new wijmo.grid.GroupRow();

  // add the row to the column footer panel
  flex.columnFooters.rows.push(row);

  // show a sigma on the header
  flex.bottomLeftCells.setCellData(0, 0, '\u03A3');
}

columnGroups

columnGroups: any[]

Gets or sets an array used to define hierarchical column groups.

The items in the array should be JSON objects with properties of Column objects, plus three optional members:

  • 'columns' array containing an array of child columns,
  • 'collapseTo' string containing the binding(s) of the child column(s) that should remain visible when the group is collapsed.
  • 'isCollapsed' boolean that determines if the group should be initially collapsed.

For example, the code below generates a grid with two column groups, both initially collapsed:

new FlexGrid('#theGrid', {
    autoGenerateColumns: false,
    columnGroups: [
        { header: 'Group 1', align: 'center', collapseTo: ['id', 'country'], isCollapsed: true, columns: [
            { binding: 'id', header: 'ID' },
            { binding: 'date', header: 'Date', dataType: 'Date' },
            { binding: 'country', header: 'Country', dataType: 'String' },
            { binding: 'active', header: 'Active', dataType: 'Boolean' },
        ]},
        { header: 'Group 2', align: 'center', collapseTo: 'sales', isCollapsed: true, columns: [
            { binding: 'sales', header: 'Sales', dataType: 'Number' },
            { binding: 'expenses', header: 'Expenses', dataType: 'Number' },
        ]}
    ],
    itemsSource: getData(20)
});

columnHeaders

columnHeaders: GridPanel

Gets the GridPanel that contains the column header cells.

columns

columns: ColumnCollection

Gets the grid's column collection.

columnsPerItem

columnsPerItem: number

Gets the number of columns used to display each item.

This value is calculated automatically based on the value of the layoutDefinition property.

commitEmptyEdits

commitEmptyEdits: boolean

Gets or sets a value that indicates how the grid commit empty edits to cell values.

The default value for this property is true.

If you choose to ignore commit empty edits, the Grid will not commit empty edits to cell values if the original value is null.

controlRect

controlRect: Rect

Gets the bounding rectangle of the control in page coordinates.

copyHeaders

copyHeaders: HeadersVisibility

Gets or sets a value that determines whether the grid should include the content of header cells when copying data to the clipboard.

This property is especially useful in read-only grids, because the header information typically should not be included when pasting data into the grid.

The default value for this property is HeadersVisibility.None for the FlexGrid control and HeadersVisibility.All for the PivotGrid control.

deferResizing

deferResizing: boolean

Gets or sets a value that determines whether row and column resizing should be deferred until the user releases the mouse button.

By default, deferResizing is set to false, causing rows and columns to be resized as the user drags the mouse. Setting this property to true causes the grid to show a resizing marker and to resize the row or column only when the user releases the mouse button.

The default value for this property is false for the FlexGrid control and true for the PivotGrid control.

editColumnIndex

editColumnIndex: number | null

Gets or sets the index of column in the row header panel that shows whether items are being edited.

The default value for this property is null, which causes the grid to show the edit glyph on the last column of the rowHeaders panel.

editRange

editRange: CellRange

Gets a CellRange that identifies the cell currently being edited.

editableCollectionView

editableCollectionView: IEditableCollectionView<T>

Gets the IEditableCollectionView that contains the grid data.

errorTip

errorTip: Tooltip | null

Gets or sets the Tooltip object used to show validation errors detected by the grid when the showErrors property is set to true.

By default, this property is set to a tooltip with zero show delay (so it appears immediately when hovering over invalid cells), no HTML content, and a "wj-error-tip" class which can be used to customize the tooltip's appearance.

Setting this property to null causes the control to use the cell's "title" attribute to show validation errors.

expandSelectionOnCopyPaste

expandSelectionOnCopyPaste: boolean

Gets or sets a value that determines whether the grid should automatically expand the selection to include cells in merged ranges when copying or pasting content to/from the clipboard.

The default value for this property is true.

frozenCells

frozenCells: IGridFreezeOptions

Gets or sets the number of frozen rows/columns in grid.

Frozen rows/columns do not scroll vertically/horizontally, but the cells they contain may be selected and edited.

frozenColumns

frozenColumns: number

Gets or sets the number of frozen columns.

Frozen columns do not scroll horizontally, but the cells they contain may be selected and edited.

The default value for this property is 0.

frozenRows

frozenRows: number

Gets or sets the number of frozen rows.

Frozen rows do not scroll vertically, but the cells they contain may be selected and edited.

The default value for this property is 0.

groupHeaderFormat

groupHeaderFormat: string | null

Gets or sets the format string used to create the group header content.

The string may contain any text, plus the following replacement strings:

  • {name}: The name of the property being grouped on.
  • {value}: The value of the property being grouped on.
  • {level}: The group level.
  • {count}: The total number of items in this group.

If a column is bound to the grouping property, the column header is used to replace the {name} parameter, and the column's format and data maps are used to calculate the {value} parameter. If no column is available, the group information is used instead.

You may add invisible columns bound to the group properties in order to customize the formatting of the group header cells.

The default value for this property is null, which causes the grid to use a culture-specific version of the string

'{name}: &lt;b&gt;{value}&lt;/b&gt;({count:n0} items)'

This default format string creates group headers similar to

'Country: &lt;b&gt;UK&lt;/b&gt; (12 items)'
'Country: &lt;b&gt;Japan&lt;/b&gt; (8 items)'

groupSummaryPosition

groupSummaryPosition: GroupSummaryPosition

Gets or sets a value that determines the position of group summary row in the group. This property does not work if childItemsPath property is set

The default value for this property is GroupSummaryPosition.Top.

headersFocusability

headersFocusability: HeadersFocusability

Gets or sets a value that determines whether the row and column headers are focusable.

The default value for this property is HeadersFocusability.None.

headersVisibility

headersVisibility: HeadersVisibility

Gets or sets a value that determines whether the row and column headers are visible.

The default value for this property is HeadersVisibility.All.

hostElement

hostElement: HTMLElement

Gets the DOM element that is hosting the control.

imeEnabled

imeEnabled: boolean

Gets or sets a value that determines whether the grid should support Input Method Editors (IME) while not in edit mode.

This property is relevant only for sites/applications in Japanese, Chinese, Korean, and other languages that require IME support.

The default value for this property is false.

isDisabled

isDisabled: boolean

Gets or sets a value that determines whether the control is disabled.

Disabled controls cannot get mouse or keyboard events.

isReadOnly

isReadOnly: boolean

Gets or sets a value that determines whether the user can modify cell values using the mouse and keyboard.

The default value for this property is false for the FlexGrid control and true for the PivotGrid control.

isTouching

isTouching: boolean

Gets a value that indicates whether the control is currently handling a touch event.

isUpdating

isUpdating: boolean

Gets a value that indicates whether the control is currently being updated.

itemFormatter

itemFormatter: IItemFormatter

Gets or sets a formatter function used to customize cells on this grid.

The formatter function can add any content to any cell. It provides complete flexibility over the appearance and behavior of grid cells.

If specified, the function should take four parameters: the GridPanel that contains the cell, the row and column indices of the cell, and the HTML element that represents the cell. The function will typically change the innerHTML property of the cell element.

For example:

flex.itemFormatter = (panel, r, c, cell) => {
  if (panel.cellType == CellType.Cell) {

    // draw sparklines in the cell
    let col = panel.columns[c];
    if (col.name == 'sparklines') {
      cell.innerHTML = getSparkline(panel, r, c);
    }
  }
}

Note that the FlexGrid recycles cells, so if your itemFormatter modifies the cell's style attributes, you must make sure that it resets these attributes for cells that should not have them. For example:

flex.itemFormatter = (panel, r, c, cell) => {

  // reset attributes we are about to customize
  let s = cell.style;
  s.color = '';
  s.backgroundColor = '';
  // customize color and backgroundColor attributes for this cell
  ...
}

If you have a scenario where multiple clients may want to customize the grid rendering (for example when creating directives or re-usable libraries), consider using the formatItem event instead. The event allows multiple clients to attach their own handlers.

itemValidator

itemValidator: IItemValidator

Gets or sets a validator function to determine whether cells contain valid data.

If specified, the validator function should take parameters containing the cell's row and column indices and a parsing parameter that describes whether the data has already been parsed and applied to the data item (parsing == false), or whether the user was trying to edit the value and entered a value that could not be parsed into the data type expected (parsing == true).

The method returns a string containing an error message, or null if no errors were detected.

For example,

grid.itemValidator = (row: number, col: number, parsing: boolean) => {
    let item = grid.rows[row].dataItem,
        prop = grid.columns[col].binding;

    // parsing failed, show message
    if (parsing) {
        if (prop == 'date') {
            return 'Please enter a valid date in the format "MM/dd/yyyy"';
        } else if (prop == 'id') {
            return 'Please enter a positive number';
        }
    }

    // check that stored (parsed) data is valid
    if (prop == 'date' && item.date < minDate) {
        return 'Please enter a date after ' + Globalize.formatDate(minDate, 'd');
    } else if (prop == 'id' && item.id < 0) {
        return 'Please enter a positive number';
    }
});

See also the CollectionView.getError method.

itemsSource

itemsSource: any

Gets or sets the array or ICollectionView that contains items shown on the grid.

keyActionEnter

keyActionEnter: KeyAction

Gets or sets the action to perform when the ENTER key is pressed.

The default setting for this property is KeyAction.MoveDown, which causes the control to move the selection to the next row. This is the standard Excel behavior.

keyActionTab

keyActionTab: KeyAction

Gets or sets the action to perform when the TAB key is pressed.

The default setting for this property is KeyAction.None, which causes the browser to select the next or previous controls on the page when the TAB key is pressed. This is the recommended setting to improve page accessibility.

Note that the default setting for the inherited FlexSheet control is KeyAction.CycleOut (see below).

In previous versions, the default was set to KeyAction.Cycle, which caused the control to move the selection across and down the grid. This is the standard Excel behavior, but is not good for accessibility.

There is also a KeyAction.CycleOut setting that causes the selection to move through the cells (as KeyAction.Cycle), and then on to the next/previous control on the page when the last or first cells are selected.

layoutDefinition

layoutDefinition: any[]

Gets or sets an array that defines the layout of each data item.

The array contains a list of cell group objects which have the following properties:

  • header: Group header (shown when the headers are collapsed).
  • colspan: Number of grid columns spanned by the group.
  • cells: Array of cell objects, which extend Column with a colspan property.

When the layoutDefinition property is set, the grid scans the cells in each group as follows:

  1. The grid calculates the colspan of the group either as group's own colspan or as span of the widest cell in the group, whichever is wider.
  2. If the cell fits the current row within the group, it is added to the current row.
  3. If it doesn't fit, it is added to a new row.

When all groups are ready, the grid calculates the number of columns per record to the maximum colspan of all groups, and adds columns to each group to pad their width as needed.

Please note that the cells support all the usual Column properties except the width property. This property can be specified in the layoutDefinition object but the grid will ignore it because it is supposed that the cells in each rows should have the same width.

lazyRender

lazyRender: boolean

Gets or sets a value that determines whether the grid should skip rendering cells that were updated in the last render cycle.

The default value for this property is true.

maxContent

maxContent: boolean

Gets or sets a value that determines whether the grid should adjust its size to fit the maximum content width and available height.

The default value for this property is false.

mergeManager

mergeManager: MergeManager

Gets or sets the MergeManager object responsible for determining how cells should be merged.

newRowAtTop

newRowAtTop: boolean

Gets or sets a value that indicates whether the new row template should be located at the top of the grid or at the bottom.

If you set the newRowAtTop property to true, and you want the new row template to remain visible at all times, set the frozenRows property to one. This will freeze the new row template at the top so it won't scroll off the view.

The new row template will be displayed only if the allowAddNew property is set to true and if the itemsSource object supports adding new items.

The default value for this property is false.

pasteEmptyCells

pasteEmptyCells: boolean

Gets or sets a value that determines whether when pasting, paste all cells or only not empty cells The default value for this property is true.

preserveOutlineState

preserveOutlineState: boolean

Gets or sets a value that determines whether the grid should preserve the expanded/collapsed state of nodes when the data is refreshed.

The preserveOutlineState property implementation is based on JavaScript's Map object, which is not available in IE 9 or 10.

The default value for this property is true.

preserveSelectedState

preserveSelectedState: boolean

Gets or sets a value that determines whether the grid should preserve the selected state of rows when the data is refreshed.

The default value for this property is true.

preserveWhiteSpace

preserveWhiteSpace: boolean

Gets or sets a value that determines whether the grid should keep whitespace in cells as they appear in the data (white-space: pre) or whether it should collapse the whitespace into a single space character (white-space: normal).

This property allows you to specify how the grid should handle white space without changing any CSS rules. You choose to use CSS rules instead, however, since they provide better control over scope.

For example, you could create CSS rules that apply to all grids in the application, to specific grids, or to specific columns.

Be aware that setting this property to true may have undesired effects in applications that use interop cell templates (Vue templates especially).

The default value for this property is false.

quickAutoSize

quickAutoSize: boolean | null

Gets or sets a value that determines whether the grid should optimize performance over precision when auto-sizing columns.

Setting this property to false disables quick auto-sizing. Setting it to true enables the feature, subject to the value of each column's wijmo.grid.Column.quickAutoSize property.

The default value for this property is null, which enables quick auto-sizing for grids that don't have a custom itemFormatter or handlers attached to the formatItem event.

Quick auto-sizing uses different strategies when auto-sizing rows or columns.

When auto-sizing columns, it uses a temporary canvas element to locate the row with the widest entry for a column. When the row is located, its contents are measured precisely. The limitation with this approach is that the canvas only renders plain text, so if cells contain HTML the auto-sizing may miss the widest column.

When auto-sizing rows, it uses a cache to store the row heights based on the cell content, and skips measuring numeric cells. The limitation with this approach is that it only improves performance if many cells have the same content, or if many columns are numeric.

If you find that auto-sizing is slowing down your application, it is probably worth setting quickAutoSize to true and checking the results to see if it works correctly and improves performance for your app.

refreshOnEdit

refreshOnEdit: boolean

Gets or sets a value that determines whether the grid should refresh all cells after a cell is edited.

The default value for this property is true.

rightToLeft

rightToLeft: boolean

Gets a value indicating whether the control is hosted in an element with right-to-left layout.

rowHeaderPath

rowHeaderPath: string

Gets or sets the name of the property used to create row header cells.

Row header cells are not visible or selectable. They are meant for use with accessibility tools.

rowHeaders

rowHeaders: GridPanel

Gets the GridPanel that contains the row header cells.

rows

rows: RowCollection

Gets the grid's row collection.

scrollPosition

scrollPosition: Point

Gets or sets a Point that represents the value of the grid's scrollbars.

scrollSize

scrollSize: Size

Gets the size of the grid content in pixels.

selectedItems

selectedItems: any[]

Gets or sets an array containing the data items that are currently selected.

Note: this property can be read in all selection modes, but it can be set only when selectionMode is set to SelectionMode.ListBox.

In unbound mode, there are no data items associated with the rows, property always returns empty array.

You can get the index of the selected row in bound and unbound modes using the selection property

selectedRanges

selectedRanges: CellRange[]

Gets or sets an array with CellRange objects that represent the current selection.

The first element in the array is the current selection. If the grid's selectionMode property is set to SelectionMode.MultiRange, the array may contain additional ranges that represent the extended selection.

Note that ranges in the selectedRanges array may contain overlapping areas, which may be important when performing actions like aggregating over the extended selection.

selectedRows

selectedRows: Row[]

Gets or sets an array containing the rows that are currently selected.

Note: this property can be read in all selection modes, but it can be set only when selectionMode is set to SelectionMode.ListBox.

selection

selection: CellRange

Gets or sets the current selection.

selectionMode

selectionMode: SelectionMode

Gets or sets the current selection mode.

showDropDown

showDropDown: boolean

Gets or sets a value that indicates whether the grid should add drop-down buttons to data-mapped cells.

The drop-down buttons are shown on columns that have a Column.dataMap and are editable.

Clicking on the drop-down buttons causes the grid to show a drop-down list from which users can select the cell value.

This setting may be overridden on specific columns using the column's Column.dataMapEditor property.

Cell drop-downs require the wijmo.input module to be loaded.

showErrors

showErrors: boolean

Gets or sets a value that determines whether the grid should add the 'wj-state-invalid' class to cells that contain validation errors and tooltips with error descriptions.

The grid detects validation errors using the itemValidator property and the CollectionView.getError property on the grid's itemsSource.

The default value for this property is true.

showGroups

showGroups: boolean

Gets or sets a value that determines whether the FlexGrid should insert group rows to delimit data groups.

Data groups are created by modifying the ICollectionView.groupDescriptions property of the ICollectionView object used as an itemsSource.

The default value for this property is true.

showMarquee

showMarquee: boolean

Gets or sets a value that indicates whether the grid should display an Excel-style marquee around the current selection.

The default value for this property is false.

If you choose to show the marquee, you may want to improve accessibility by using some simple CSS to make the marquee fully opaque only when the grid has the focus:

.wj-flexgrid:not(.wj-state-focused) .wj-marquee {
    opacity: 0.2;
}

showPlaceholders

showPlaceholders: boolean

Gets or sets a value that determines whether the grid should use the column headers as placeholders when editing cells.

The default value for this property is false.

This property is especially useful in grids that have multiple rows per data item (like the MultiRow grid) and in grids that allow adding new items (see the allowAddNew property).

This property only works with the grid's built-in editor. If you are using custom editors (see the Column.editor property), then you are responsible for setting the placeholder property on those.

The Internet Explorer browser does not show input placeholders on focused input elements, so this property is not useful in IE.

showSelectedHeaders

showSelectedHeaders: HeadersVisibility

Gets or sets a value that indicates whether the grid should add class names to indicate selected header cells.

The default value for this property is HeadersVisibility.None.

showSort

showSort: boolean

Gets or sets a value that determines whether the grid should display sort indicators in the column headers.

Sorting is controlled by the ICollectionView.sortDescriptions property of the ICollectionView object used as a the grid's itemsSource.

The default value for this property is true.

skipMerged

skipMerged: boolean

Gets or sets a value that determines whether when copying, skip cells that have been merged The default value for this property is false.

sortRowIndex

sortRowIndex: number | null

Gets or sets the index of row in the column header panel that shows and changes the current sort.

The default value for this property is null, which causes the bottom row in the columnHeaders panel to act as the sort row.

stickyHeaders

stickyHeaders: boolean

Gets or sets a value that determines whether column headers should remain visible when the user scrolls the document.

The default value for this property is false.

tabOrder

tabOrder: number

Gets or sets a value of the tabindex attribute associated with the control.

tabindex attribute value can be defined statically for a Wijmo control by specifying it on the control's host HTML element. But this value can't be changed later during application lifecycle, because Wijmo controls have complex structure, and the control may need to propagate this attribute value to its internal element to work properly.

Because of this, to read or change control's tabindex dynamically, you should do it using this property.

topLeftCells

topLeftCells: GridPanel

Gets the GridPanel that contains the top left cells (to the left of the column headers).

treeIndent

treeIndent: number

Gets or sets the indent used to offset row groups of different levels.

The default value for this property is 14 pixels for the FlexGrid control, and 32 pixels for the PivotGrid.

validateEdits

validateEdits: boolean

Gets or sets a value that determines whether the grid should remain in edit mode when the user tries to commit edits that fail validation.

The grid detects validation errors by calling the CollectionView.getError method on the grid's itemsSource.

The default value for this property is true.

viewRange

viewRange: CellRange

Gets the range of cells currently in view.

virtualizationThreshold

virtualizationThreshold: number | number[]

Gets or sets the minimum number of rows and/or columns required to enable virtualization.

This property is set to zero by default, meaning virtualization is always enabled. This improves binding performance and memory requirements, at the expense of a small performance decrease while scrolling.

If your grid has a small number of rows (about 50 to 100), you may be able to improve scrolling performance by setting this property to a slightly higher value (like 150). This will disable virtualization and will slow down binding, but may improve perceived scroll performance. For example, the code below sets causes the grid to virtualize cells when the data source has more than 150 items:

// virtualize grid when there are more than 150 items
theGrid.virtualizationThreshold = 150;

Setting this property to values higher than 200 is not recommended. Loading times will become too long; the grid will freeze for a few seconds while creating cells for all rows, and the browser will become slow because of the large number of elements on the page.

If you want to set separate virtualization thresholds for rows and columns, you may set the virtualizationThreshold property to an array with two numbers. In this case, the first number will be used as the row threshold and the second as the column threshold. For example, the code below sets causes the grid to virtualize rows but not columns:

// virtualize rows (threshold 0) but not columns (threshold 10,000)
theGrid.virtualizationThreshold = [0, 10000];

The default value for this property is 0, which causes the grid to virtualize all rows and columns.

Static controlTemplate

controlTemplate: string

Gets or sets the template used to instantiate FlexGrid controls.

Static defaultTypeWidth

defaultTypeWidth: object

Gets a reference to a static object that defines the default width for auto-generated grid columns based on their types.

The object keys are DataType values. The object values are either numbers (widths in pixels) or star-size strings (multiples of the default width defined by the columns defaultSize property).

For example:

import { FlexGrid } from '@mescius/wijmo.grid';
import { DataType } from '@mescius/wijmo';

// make boolean columns on all grids 100px wide by default
FlexGrid.defaultTypeWidth[DataType.Boolean] = 100;

// make numeric columns on all grids 75% as wide as the columns defaultSize
FlexGrid.defaultTypeWidth[DataType.Number] = '0.75*';

Methods

addEventListener

  • addEventListener(target: EventTarget, type: string, fn: any, capture?: boolean, passive?: boolean): void

  • Adds an event listener to an element owned by this Control.

    The control keeps a list of attached listeners and their handlers, making it easier to remove them when the control is disposed (see the dispose and removeEventListener methods).

    Failing to remove event listeners may cause memory leaks.

    The passive parameter is set to false by default, which means the event handler may call event.preventDefault(). If you are adding passive handlers to touch or wheel events, setting this parameter to true will improve application performance.

    For details on passive event listeners, please see Improving scrolling performance with passive listeners.

    Parameters

    • target: EventTarget

      Target element for the event.

    • type: string

      String that specifies the event.

    • fn: any

      Function to execute when the event occurs.

    • Optional capture: boolean

      Whether the listener should be handled by the control before it is handled by the target element.

    • Optional passive: boolean

      Indicates that the handler will never call preventDefault().

    Returns void

adjustFrozenRowColSize

  • adjustFrozenRowColSize(index: number, type: FrozenRowCol, delta?: number): void

  • Adjusts the size of a column/row ensuring the total size of frozen elements does not exceed the grid size.

    Parameters

    Returns void

applyTemplate

  • applyTemplate(classNames: string, template: string, parts: Object, namePart?: string): HTMLElement

  • Applies the template to a new instance of a control, and returns the root element.

    This method should be called by constructors of templated controls. Therefore, this method is not available. It is responsible for binding the template parts to the corresponding control members.

    For example, the code below applies a template to an instance of an InputNumber control. The template must contain elements with the 'wj-part' attribute set to 'input', 'btn-inc', and 'btn-dec'. The control members '_tbx', '_btnUp', and '_btnDn' will be assigned references to these elements.

    this.applyTemplate('wj-control wj-inputnumber', templateString, {
  _tbx: 'input',
  _btnUp: 'btn-inc',
  _btnDn: 'btn-dec'
}, 'input');

    @param classNames Names of classes to add to the control's host element. @param template An HTML string that defines the control template. @param parts A dictionary of part variables and their names. @param namePart Name of the part to be named after the host element. This determines how the control submits data when used in forms.

    Parameters

    • classNames: string
    • template: string
    • parts: Object
    • Optional namePart: string

    Returns HTMLElement

autoSizeColumn

  • autoSizeColumn(c: number, header?: boolean, extra?: number): void

  • Resizes a column to fit its content.

    This method only works if the grid is visible. If its host element has not been added to the DOM, or if any of the grid's ancestor elements is hidden, the grid will not be able to measure the cells and therefore will not be able to auto-size the columns.

    Parameters

    • c: number

      Index of the column to resize.

    • Optional header: boolean

      Whether the column index refers to a regular or a header row.

    • Optional extra: number

      Extra spacing, in pixels.

    Returns void

autoSizeColumns

  • autoSizeColumns(firstColumn?: number, lastColumn?: number, header?: boolean, extra?: number): void

  • Resizes a range of columns to fit their content.

    The grid will always measure all rows in the current view range, plus up to 2,000 rows not currently in view. If the grid contains a large amount of data (say 50,000 rows), then not all rows will be measured since that could take a long time.

    This method only works if the grid is visible. If its host element has not been added to the DOM, or if any of the grid's ancestor elements is hidden, the grid will not be able to measure the cells and therefore will not be able to auto-size the columns.

    Parameters

    • Optional firstColumn: number

      Index of the first column to resize (defaults to the first column).

    • Optional lastColumn: number

      Index of the last column to resize (defaults to the last column).

    • Optional header: boolean

      Whether the column indices refer to regular or header columns.

    • Optional extra: number

      Extra spacing, in pixels.

    Returns void

autoSizeRow

  • autoSizeRow(r: number, header?: boolean, extra?: number): void

  • Resizes a row to fit its content.

    This method only works if the grid is visible. If its host element has not been added to the DOM, or if any of the grid's ancestor elements are hidden, the grid will not be able to measure the cells and therefore will not be able to auto-size the rows.

    Parameters

    • r: number

      Index of the row to resize.

    • Optional header: boolean

      True to indicate the row index refers to a header row, false to indicate it refers to a regular data row, or null to indicate it refers to a footer row.

    • Optional extra: number

      Extra spacing, in pixels.

    Returns void

autoSizeRows

  • autoSizeRows(firstRow?: number, lastRow?: number, header?: boolean, extra?: number): void

  • Resizes a range of rows to fit their content.

    This method only works if the grid is visible. If its host element has not been added to the DOM, or if any of the grid's ancestor elements is hidden, the grid will not be able to measure the cells and therefore will not be able to auto-size the rows.

    Parameters

    • Optional firstRow: number

      Index of the first row to resize.

    • Optional lastRow: number

      Index of the last row to resize.

    Hidden rows and columns are not included in the clip string.

    Invalid (with negative indexes) row or column ranges can be specified in CellRange, which indicates that data rows or columns are not included in the result. In conjunction with colHeaders or rowHeaders parameters set to true, this makes it possible to export colum or row headers only, without the corresponding data cells.

    Parameters

    • Optional rng: CellRange | null

      CellRange to copy. If omitted, the current selection is used.

    • Optional options: boolean | ClipStringOptions

    • Optional colHeaders: boolean

      Whether to include the column headers.

    • Optional rowHeaders: boolean

      Whether to include the row headers.

      To export the current selection, set the rng parameter to null. This will include not only the primary selection but also extended selections such as selected rows (in SelectionMode.ListBox mode) and multiple selected ranges (in SelectionMode.MultiRange mode).

      Note that multiple selected ranges are included only if all selected ranges refer to the same column range or row range.

    Returns string

getColumn

  • getColumn(name: string | number, header?: boolean): Column

  • Gets a column by name or by binding.

    The method searches the column by name. If a column with the given name is not found, it searches by binding. The searches are case-sensitive.

getSelectedState

getTemplate

  • getTemplate(): string

  • Gets the HTML template used to create instances of the control.

    This method traverses up the class hierarchy to find the nearest ancestor that specifies a control template. For example, if you specify a prototype for the ComboBox control, which does not specify a template, it will override the template defined by the DropDown base class (the nearest ancestor that does specify a template).

    Returns string

hasOwnProperty

  • hasOwnProperty(v: PropertyKey): boolean

  • Determines whether an object has a property with the specified name.

    Parameters

    • v: PropertyKey

      A property name.

    For example:

    // hit test a point when the user clicks on the grid
flex.hostElement.addEventListener('click', (e) => {
  let ht = flex.hitTest(e.pageX, e.pageY);
  console.log('you clicked a cell of type "' +
    wijmo.grid.CellType[ht.cellType] + '".');
});

    Returns HitTestInfo

    A wijmo.grid.HitTestInfo object with information about the point.

initialize

  • initialize(options: any): void

  • Initializes the control by copying the properties from a given object.

    This method allows you to initialize controls using plain data objects instead of setting the value of each property in code.

    For example:

    grid.initialize({
  itemsSource: myList,
  autoGenerateColumns: false,
  columns: [
    { binding: 'id', header: 'Code', width: 130 },
    { binding: 'name', header: 'Name', width: 60 }
  ]
});

// is equivalent to
grid.itemsSource = myList;
grid.autoGenerateColumns = false;
// etc.

    The initialization data is type-checked as it is applied. If the initialization object contains unknown property names or invalid data types, this method will throw.

    Parameters

    • options: any

      Object that contains the initialization data.

    Returns void

invalidate

  • invalidate(fullUpdate?: boolean): void

  • Invalidates the control causing an asynchronous refresh.

    Returns void

refreshRange

  • Refreshes the cells in a range, updating their content and styles.

    Unlike the refreshCells method, which updates all the cells, refreshRange allows you to specify which cells should be refreshed, which in some cases can improve performance.

    Parameters

    Returns void

removeEventListener

  • removeEventListener(target?: EventTarget, type?: string, fn?: any, capture?: boolean): number

  • Removes one or more event listeners attached to elements owned by this Control.

    Parameters

    • Optional target: EventTarget

      Target element for the event. If null, removes listeners attached to all targets.

    • Optional type: string

      String that specifies the event. If null, removes listeners attached to all events.

    • Optional fn: any

      Handler to remove. If null, removes all handlers.

scrollIntoView

  • scrollIntoView(r: number, c: number | string, refresh?: boolean): boolean

  • Scrolls the grid to bring a specific cell into view.

    Negative row and column indices are ignored, so if you call

    grid.scrollIntoView(200, -1);

    The grid will scroll vertically to show row 200, and will not scroll horizontally.

    Parameters

    • r: number

      Index of the row to scroll into view.

    • c: number | string

      Index, name, or binding of the column to scroll into view.

    • Optional refresh: boolean

      Optional parameter that determines whether the grid should refresh to show the new scroll position immediately.

    Returns boolean

    True if the grid scrolled.

select

  • select(rng: number | CellRange, show?: string | number | false | true, panel?: GridPanel): boolean

  • Selects a cell range and optionally scrolls it into view.

    The select method can be called by passing a CellRange and an optional boolean parameter that indicates whether the new selection should be scrolled into view. For example:

    // select cell 1,1 and scroll it into view
grid.select(new CellRange(1, 1), true);

// select range (1,1)-(2,4) and do not scroll it into view
grid.select(new CellRange(1, 1, 2, 4), false);

    You can also call the select method passing the index or the row and column you want to select. In this case, the new selection always scrolls into view. For example:

    // select cell 1,1 and scroll it into view
grid.select(1, 1);

    Parameters

    • rng: number | CellRange

      Range to select (or index of the row to select).

    Parameters

    • r: number

      Index of the row that contains the cell.

    • c: string | number

      Index, name, or binding of the column that contains the cell.

    • value: any

      Value to store in the cell.

    • Optional coerce: boolean

      Whether to change the value automatically to match the column's data type.

    • Optional invalidate: boolean

      Whether to invalidate the grid to show the change.

    Returns boolean

    True if the value was stored successfully, false otherwise.

setClipString

  • setClipString(text: string, rng?: CellRange): void

  • Parses a string into rows and columns and applies the content to a given range.

    Hidden rows and columns are skipped.

    Parameters

    • text: string

      Tab and newline delimited text to parse into the grid.

    • Optional rng: CellRange

      CellRange to copy. If omitted, the current selection is used.

    Returns void

startEditing

  • startEditing(fullEdit?: boolean, r?: number, c?: number | string, focus?: boolean, evt?: any): boolean

  • Starts editing a given cell.

    Editing in the FlexGrid is similar to editing in Excel: Pressing F2 or double-clicking a cell puts the grid in full-edit mode. In this mode, the cell editor remains active until the user presses Enter, Tab, or Escape, or until he moves the selection with the mouse. In full-edit mode, pressing the cursor keys does not cause the grid to exit edit mode.

    Typing text directly into a cell puts the grid in quick-edit mode. In this mode, the cell editor remains active until the user presses Enter, Tab, or Escape, or any arrow keys.

    Full-edit mode is normally used to make changes to existing values. Quick-edit mode is normally used for entering new data quickly.

    While editing, the user can toggle between full and quick modes by pressing the F2 key.

    Parameters

    • Optional fullEdit: boolean

      Whether to stay in edit mode when the user presses the cursor keys. Defaults to true.

    • Optional r: number

      Index of the row to be edited. Defaults to the currently selected row.

    • Optional c: number | string

      Index, name, or binding of the column to be edited. Defaults to the currently selected column.

    • Optional focus: boolean

      Whether to give the editor the focus when editing starts. Defaults to true.

    • Optional evt: any

      Event that triggered this action (usually a keypress or keydown).

    Returns boolean

    True if the edit operation started successfully.

toLocaleString

  • toLocaleString(): string

  • Returns a date converted to a string using the current locale.

    Returns string

toString

  • toString(): string

  • Returns a string representation of an object.

    Returns string

toggleDropDownList

  • toggleDropDownList(): boolean

  • Toggles the visibility of the drop-down list box associated with the currently selected cell.

    The drop-down list is created automatically based on the column's Column.dataMap property.

    This method can be used to show the drop-down list automatically when the cell enters edit mode, or when the user presses certain keys.

    For example, this code causes the grid to show the drop-down list whenever the grid enters edit mode:

    // show the drop-down list when the grid enters edit mode
theGrid.beginningEdit.addHandler(() => {
  theGrid.toggleDropDownList();
});

    This code causes the grid to show the drop-down list when the grid enters edit mode after the user presses the space bar:

    // show the drop-down list when the user presses the space bar
theGrid.hostElement.addEventListener('keydown', (e) => {
  if (e.keyCode == 32) {
    e.preventDefault();
    theGrid.toggleDropDownList();
  }
}, true);

    Returns boolean

valueOf

  • valueOf(): Object

  • Returns the primitive value of the specified object.

    Returns Object

Static disposeAll

  • disposeAll(e?: HTMLElement): void

  • Disposes of all Wijmo controls contained in an HTML element.

    Parameters

    • Optional e: HTMLElement

      Container element.

    Returns void

Static getControl

  • getControl(element: any): Control

  • Gets the control that is hosted in a given DOM element.

    Parameters

    • element: any

      The DOM element that hosts the control, or a CSS selector for the host element (e.g. '#theCtrl').

    Returns Control

Static invalidateAll

  • invalidateAll(e?: HTMLElement): void

  • Invalidates all Wijmo controls contained in an HTML element.

    Use this method when your application has dynamic panels that change the control's visibility or dimensions. For example, splitters, accordions, and tab controls usually change the visibility of its content elements. In this case, failing to notify the controls contained in the element may cause them to stop working properly.

    If this happens, you must handle the appropriate event in the dynamic container and call the Control.invalidateAll method so the contained Wijmo controls will update their layout information properly.

    Parameters

    • Optional e: HTMLElement

      Container element. If set to null, all Wijmo controls on the page will be invalidated.

    Returns void

Static refreshAll

  • refreshAll(e?: HTMLElement): void

  • Refreshes all Wijmo controls contained in an HTML element.

    This method is similar to invalidateAll, except the controls are updated immediately rather than after an interval.

    Parameters

    • Optional e: HTMLElement

      Container element. If set to null, all Wijmo controls on the page will be invalidated.

    Returns void

Events

beginningEdit

beginningEdit: Event<FlexGrid<any>, CellRangeEventArgs>

Occurs before a cell enters edit mode.

The 'data' property of the handler parameters contains a reference to the DOM event that caused the grid to enter edit mode.

The event handler may cancel the edit operation.

cellEditEnded

cellEditEnded: Event<FlexGrid<any>, CellRangeEventArgs>

Occurs when a cell edit has been committed or canceled.

cellEditEnding

cellEditEnding: Event<FlexGrid<any>, CellEditEndingEventArgs>

Occurs when a cell edit is ending.

You can use this event to perform validation and prevent invalid edits. For example, the code below prevents users from entering values that do not contain the letter 'a'. The code demonstrates how you can obtain the old and new values before the edits are applied.

function cellEditEnding(flex, e) {

  // get old and new values
  let oldVal = e.previousData,
      newVal = flex.activeEditor.value;

  // cancel edits if newVal doesn't contain 'a'
  e.cancel = newVal.indexOf('a') < 0;
}

Setting the CellEditEndingEventArgs.cancel parameter to true causes the grid to discard the edited value and keep the cell's original value.

If you also set the CellEditEndingEventArgs.stayInEditMode parameter to true, the grid will remain in edit mode so the user can correct invalid entries before committing the edits.

columnGroupCollapsedChanged

columnGroupCollapsedChanged: Event<FlexGrid<any>, CellRangeEventArgs>

Occurs after a column group has been expanded or collapsed.

The 'data' property of the handler parameters contains a reference to the ColumnGroup that is about to change.

// remember column being dragged
flex.draggingColumn.addHandler((s, e) => {
    theColumn = s.columns[e.col].binding;
});

// prevent 'sales' column from being dragged to index 0
s.draggingColumnOver.addHandler((s, e) => {
    if (theColumn == 'sales' && e.col == 0) {
        e.cancel = true;
    }
});

formatItem

formatItem: Event<FlexGrid<any>, FormatItemEventArgs>

Occurs when an element representing a cell has been created.

This event can be used to format cells for display. It is similar in purpose to the itemFormatter property, but has the advantage of allowing multiple independent handlers.

For example, this code removes the 'wj-wrap' class from cells in group rows:

flex.formatItem.addHandler((flex, e) => {
  if (flex.rows[e.row] instanceof GroupRow) {
    wijmo.removeClass(e.cell, 'wj-wrap');
  }
});

Occurs when invalid input is detected.

Invalid input may occur when the user types or pastes a value that cannot be converted to the proper type, or a value that is outside the valid range.

If the event handler cancels the event, the control will retain the invalid content and the focus, so users can correct the error.

If the event is not canceled, the control will ignore the invalid input and will retain the original content.

rowEditEnding

rowEditEnding: Event<FlexGrid<any>, CellRangeEventArgs>

Occurs when a row edit is ending, before the changes are committed or canceled.

This event can be used in conjunction with the rowEditStarted event to implement deep-binding edit undos. For example:

// save deep bound values when editing starts
let itemData = {};
s.rowEditStarted.addHandler((s, e) => {
  let item = s.collectionView.currentEditItem;
  itemData = {};
  s.columns.forEach(function (col) {
    if (col.binding.indexOf('.') &gt; -1) { // deep binding
      let binding = new wijmo.Binding(col.binding);
      itemData[col.binding] = binding.getValue(item);
    }
  })
});

// restore deep bound values when edits are canceled
s.rowEditEnded.addHandler((s, e) => {
  if (e.cancel) { // edits were canceled by the user
    let item = s.collectionView.currentEditItem;
    for (let k in itemData) {
