DataViewBase.DetailHeaderContent Property

Gets or sets the detail section’s header content.

Namespace: DevExpress.Xpf.Grid

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

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public object DetailHeaderContent { get; set; }

VB.NET

Public Property DetailHeaderContent As Object

Property Value

Type	Description
Object	An object representing the detail section’s header content.

Remarks

Details display header sections when the DetailDescriptorBase.ShowHeader option is enabled. When using a DataControlDetailDescriptor, you can specify the header section content via the detail Grid View’s DataViewBase.DetailHeaderContent. If no template has been assigned to the DetailDescriptorBase.HeaderContentTemplate, then the header will display the textual representation of the assigned content object. If you specify a template, then the DataViewBase.DetailHeaderContent will define the DataContext for the template.

The following image shows a detail header section’s default representation (when no template has been assigned).

The DetailHeaderContent property also specifies the string representation of the Detail section within the Group Panel, Filter Panel and detail tab headers. For ContentDetailDescriptor objects, use the ContentDetailDescriptor.HeaderContent property. The following image shows these two properties in action.

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).
