DetailDescriptorSelector Class
Enables you to select which detail descriptor to use in data dependent details.
Namespace: DevExpress.Xpf.Grid
Assembly: DevExpress.Xpf.Grid.v24.2.Core.dll
NuGet Package: DevExpress.Wpf.Grid.Core
Declaration
Example
In this example, the DetailDescriptorSelector displays different details based on the master row’s content. Assign the default detail descriptor to the DetailDescriptorSelector.DefaultValue property and use DetailDescriptorTriggers to conditionally switch it to an another detail. This trigger has the Binding and Value properties which work similarly to corresponding properties in a standard WPF DataTrigger.
<dxg:GridControl AutoGenerateColumns="AddNew" ItemsSource="{Binding Tasks}">
<dxg:GridControl.DetailDescriptor>
<dxg:DetailDescriptorSelector>
<dxg:DetailDescriptorSelector.DefaultValue>
<dxg:DataControlDetailDescriptor ItemsSourcePath="CompletedActions">
<dxg:GridControl AutoGenerateColumns="AddNew">
<dxg:GridControl.View>
<dxg:TableView ShowGroupPanel="False"/>
</dxg:GridControl.View>
</dxg:GridControl>
</dxg:DataControlDetailDescriptor>
</dxg:DetailDescriptorSelector.DefaultValue>
<dxg:DetailDescriptorTrigger Binding="{Binding Succeed}" Value="False">
<dxg:DataControlDetailDescriptor ItemsSourcePath="Errors">
<dxg:GridControl AutoGenerateColumns="AddNew">
<dxg:GridControl.View>
<dxg:TableView ShowGroupPanel="False"/>
</dxg:GridControl.View>
</dxg:GridControl>
</dxg:DataControlDetailDescriptor>
</dxg:DetailDescriptorTrigger>
</dxg:DetailDescriptorSelector>
</dxg:GridControl.DetailDescriptor>
<dxg:GridControl.View>
<dxg:TableView AutoWidth="True" ShowGroupPanel="False"/>
