The following code sample demonstrates how to add a checkbox to the column header using the ColumnBase.HeaderCustomizationAreaTemplate property:

XAML

<dxg:GridColumn FieldName="CategoryName">
   <dxg:GridColumn.HeaderCustomizationAreaTemplate>
      <DataTemplate>
         <dxe:CheckEdit IsChecked="{Binding Column.ReadOnly, Mode=TwoWay}" />
      </DataTemplate>
   </dxg:GridColumn.HeaderCustomizationAreaTemplate>
</dxg:GridColumn>

View Example: Display a Check Box in Column Headers

Use the ColumnBase.ActualHeaderCustomizationAreaTemplateSelector property to obtain the actual template selector.

If you have more than one template for rendering a customization area, specify the ColumnBase.HeaderCustomizationAreaTemplateSelector property to implement custom logic for selecting the required template.
