ContentDetailDescriptor Class
Represents a Detail with freely-customizable content.
Namespace: DevExpress.Xpf.Grid
Assembly: DevExpress.Xpf.Grid.v23.2.Core.dll
NuGet Package: DevExpress.Wpf.Grid.Core
Declaration
Remarks
When setting up master-detail hierarchy, the Detail may display either another grid or custom controls. If you choose to display custom controls, you will need to use the ContentDetailDescriptor object in one of the following ways:
- assign it to the master grid’s GridControl.DetailDescriptor property;
- add it to the MultiDetailDescriptor.DetailDescriptors collection of a TabViewDetailDescriptor if you are setting up tabbed details.
The following are the main members in the ContentDetailDescriptor class that you will need to work with:
| Member | Description |
|---|---|
| DetailDescriptorBase.ContentTemplate | Gets or sets the template specifying the entire or partial content of a Detail. |
| ContentDetailDescriptor.HeaderContent | Gets or sets the detail section’s header content. This is a dependency property. |
Example
This example displays the memo field and the Chart Control in grid details. The memo field displays data from the master row, and the chart is bound to detail data. The DataTemplate that contains these two controls is asigned to both ContentDetailDescriptor and DataControlDetailDescriptor:
- The ContentDetailDescriptor tab displays the custom content only.
- The DataControlDetailDescriptor tab displays the custom content above the detail GridControl.
