Properties

column

column: Column

Gets the Column being filtered.

conditionFilter

conditionFilter: ConditionFilter

Gets the ConditionFilter in this ColumnFilter.

dataMap

dataMap: DataMap

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;
    }
}
