ContentDetailDescriptor.HeaderContent Property

Gets or sets the detail section’s header content. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v24.1.Core.dll

Declaration

public object HeaderContent { get; set; }

Property Value

Type Description
Object

An object specifying the detail section’s header content.

Remarks

Details display header sections when their DetailDescriptorBase.ShowHeader option is enabled. For details represented by ContentDetailDescriptor objects, header section content is specified by the HeaderContent property. If no template has been assigned to the DetailDescriptorBase.HeaderContentTemplate, then the header displays the textual representation of an assigned object. If a template has been assigned, then the HeaderContent property will define the DataContext for this template.

The following image shows a header section when no template is assigned to the DetailDescriptorBase.HeaderContentTemplate property.

Grid-Master-Detail-Header-Content

This property’s textual representation is also used in tab headers when using a ContentDetailDescriptor within a TabViewDetailDescriptor. The following image illustrates this usage and also shows the DataViewBase.DetailHeaderContent property that should be used instead of HeaderContent when using a DataControlDetailDescriptor.

Master-Detail-Header-Content

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).
