GridControl.DetailDescriptor Property

Enables master-detail representation within this GridControl.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v23.2.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public DetailDescriptorBase DetailDescriptor { get; set; }

VB.NET

Public Property DetailDescriptor As DetailDescriptorBase

Property Value

Type	Description
DetailDescriptorBase	A DetailDescriptorBase descendant specifying which details to display for this GridControl.

Remarks

This property is crucial to setting up the master-detail hierarchy within the GridControl. You need to initialize it with a proper DetailDescriptorBase descendant as outlined in the following table.

Detail Descriptor	Purpose
DataControlDetailDescriptor	Use this object to display another GridControl or any DataControlBase descendant within the Detail View. When using a GridControl, Detail View synchronization and Master View integration become avialable.
ContentDetailDescriptor	Use this object to display any set of controls within the Detail View. You can also use it to display a GridControl if you don’t want Detail View synchronization or Master View Integration features that become enabled when using the DataControlDetailDescriptor.
TabViewDetailDescriptor	Use this object to display multiple details within a tabbed container.

Refer to the following help topic for more information: Master-Detail Data Representation.

Example

This example creates tabbed details (TabViewDetailDescriptor) in the GridControl. The Orders tab displays the GridControl (DataControlDetailDescriptor), and the Notes tab displays a memo field (ContentDetailDescriptor).

View Example: Display Detail Content in Tabs
