MultiDetailDescriptor.DetailDescriptors Property

Provides access to Detail Descriptors to be displayed by this multi-detail container.

Namespace: DevExpress.Xpf.Grid

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

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public DetailDescriptorCollection DetailDescriptors { get; }

VB.NET

Public ReadOnly Property DetailDescriptors As DetailDescriptorCollection

Property Value

Type	Description
DetailDescriptorCollection	A DetailDescriptorCollection object containing Detail Descriptors to be displayed by this multi-detail container.

Remarks

When you need a GridControl to display multiple details, you need to assign a MultiDetailDescriptor descendant to the GridControl.DetailDescriptor property. This can be a TabViewDetailDescriptor object or another descendant. Once the required object is assigned, you need to populate it’s DetailDescriptors collection with Detail Descriptors that you want to display.

Example

This example creates a master-detail GridControl in code-behind. The example creates a tabbed detail (TabViewDetailDescriptor) that contains the following tabs:

• The Orders tab uses the DataControlDetailDescriptor to display the GridControl.
• The Notes tab uses the ContentDetailDescriptor to display a memo field.
• The Stats tab uses the ContentDetailDescriptor to display the Chart Control.
