Property Value

Type	Description
DataTemplate	A DataTemplate object that defines the presentation of a custom column filter.

Remarks

To create a custom drop-down filter:

• Set the ColumnBase.FilterPopupMode property to FilterPopupMode.Custom / FilterPopupMode.ExcelSmart.

• Create a template that represents the drop-down filter and assign it to the ColumnBase.CustomColumnFilterPopupTemplate property (see Example 1).

  You can define a filter element with the PART_FilterElement name as a custom data template (see Example 2).

Example 1

The following code sample demonstrates how to create a custom drop-down filter for the Index column:

Run Demo: Custom Filter Popup Content

The following code sample uses the RangeFilterElement as a custom data template:

Xaml

<dxg:GridControl x:Name="grid" ItemsSource="...">
    <dxg:GridControl.Columns>
        <!-- -->
        <dxg:GridColumn FieldName="Quantity">
            <dxg:GridColumn.CustomColumnFilterPopupTemplate>
                <DataTemplate>
                    <dxfui:RangeFilterElement x:Name="PART_FilterElement"/>
                </DataTemplate>
            </dxg:GridColumn.CustomColumnFilterPopupTemplate>
