constructor(owner: FlexSheetFilter, column: Column): FlexSheetColumnFilter
Initializes a new instance of the FlexSheetColumnFilter class.
The FlexSheetFilter that owns this column filter.
The Column to filter.
Gets the ConditionFilter in this ColumnFilter.
Gets or sets the DataMap used to convert raw values into display values shown when editing this filter.
The example below assigns a DataMap to Boolean column filters so the filter editor displays 'Yes' and 'No' instead of 'true' and 'false':
import { FlexGridFilter } from '@mescius/wijmo.grid.filter';
var filter = new FlexGridFilter(grid),
map = new wijmo.grid.DataMap([
{ value: true, caption: 'Yes' },
{ value: false, caption: 'No' },
], 'value', 'caption');
for (var c = 0; c < grid.columns.length; c++) {
if (grid.columns[c].dataType == wijmo.DataType.Boolean) {
filter.getColumnFilter(c).dataMap = map;
}
}
Gets or sets the types of filtering provided by this filter.
Setting this property to null causes the filter to use the value defined by the owner filter's defaultFilterType property.
Gets a value that indicates whether the filter is active.
apply(value: any): boolean
Gets a value that indicates whether a value passes the filter.
The value to test.
implementsInterface(interfaceName: string): boolean
Returns true if this object supports a given interface.
Name of the interface to look for.
Defines a filter for a column on a FlexSheet control.
The FlexSheetColumnFilter contains a FlexSheetConditionFilter and a FlexSheetValueFilter; only one of them may be active at a time.
This class is used by the FlexSheetFilter class; you rarely use it directly.
