Filtering UI

The DataGrid supports filtering through the UI.

Filtering UI appears when clicking on the filtering icon on each column's header'.

The Filtering UI exposes the following properties:

• UserFilterMode—Defines whether the Filtering UI is enabled/disabled. The available options are Auto, Enabled, and Disabled. The default value of the UserFilterMode is Auto. Set the property on DataGrid control.

• CanUserFilter(bool) property is used to enable/disable the filtering of a specific column. Set the property to a specific column.

• ShowDistinctValuesFilter(bool)—Defines whether the distinct values are included in the Filtering UI. By default the value is true.

• FilterContentTemplate(DataTemplate)—Defines the content template of the DataGrid Columns Filter and overriding the default template.

Events related to DistinctValuesFilter:

• DistinctValuesLoading event—Occurs when loading the distinct values that will be displayed in the Telerik.Maui.Controls.Compatibility.DataGrid.DataGridDistinctValuesFilterView. The DistinctValuesLoading event handler receives two parameters:
  • The sender argument, which is of type object, but can be cast to the RadDataGrid type.
  • A DistinctValuesLoadingEventArgs object, which provides the following properties:
    • DistinctValues—Is a property which specifies a list of values of type IEnumerable which are to be displayed in the DataGridDistinctValuesFilterView.
    • Column—Is a readonly property of type DataGridColumn which gets the column for which the distinct values are being loaded.
