Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v20.1.Core.dll

Declaration

public object HeaderContent { get; set; }
Public Property HeaderContent As Object

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

Examples

The following example shows how to create a new grid and set up Master-Detail data representation in code. When setting up a Master-Detail hierarchy, a detail grid and a custom detail section are placed within a tabbed container. So, the following Detail Descriptor types are used: DataControlDetailDescriptor, ContentDetailDescriptor, and TabViewDetailDescriptor.

<dxg:GridControl Grid.Row="0" Name="gridControl1" AutoGenerateColumns="AddNew" >
    <dxg:GridControl.View>
        <dxg:TableView DetailHeaderContent="Employees" AutoWidth="True" ShowGroupPanel="False"  />
    </dxg:GridControl.View>
    <dxg:GridControl.DetailDescriptor>
        <dxg:TabViewDetailDescriptor>
            <dxg:TabViewDetailDescriptor.DetailDescriptors>
                <dxg:DataControlDetailDescriptor ItemsSourcePath="Orders">
                    <dxg:DataControlDetailDescriptor.DataControl>
                        <dxg:GridControl AutoGenerateColumns="AddNew">
                            <dxg:GridControl.View>
                                <dxg:TableView DetailHeaderContent="Orders" AutoWidth="True" ShowGroupPanel="False" />
                            </dxg:GridControl.View>
                        </dxg:GridControl>
                    </dxg:DataControlDetailDescriptor.DataControl>
                </dxg:DataControlDetailDescriptor>
                <dxg:ContentDetailDescriptor ContentTemplate="{StaticResource EmployeeNotes}" HeaderContent="Notes">
                </dxg:ContentDetailDescriptor>
            </dxg:TabViewDetailDescriptor.DetailDescriptors>
        </dxg:TabViewDetailDescriptor>
    </dxg:GridControl.DetailDescriptor>
</dxg:GridControl>
