-
filter() / filter(filterExpr)
Gets or sets a filter expression for the grid's dataSource. -
filterValue
A filter expression that is applied with the following UI elements: filter row, header filter, filter builder. -
getCombinedFilter() / getCombinedFilter(returnDataField)
Gets the total filter that includes filters from the UI elements and the filter applied to the dataSource. If you specify thereturnDataFieldparameter, the returned value contains data field names instead of getters. -
clearFilter() / clearFilter(filterName)
Discards all filters applied to the DataGrid. If you specify thefilterNameparameter, this method discards all filters of a specific type.
In this demo, you can use the SelectBox component to filter the grid's dataSource. The "All" item calls the clearFilter() method and the other items call the filter(filterExpr) method.
