GridViewBase.GroupValueTemplate Property

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v18.2.dll

Declaration

C#

public DataTemplate GroupValueTemplate { get; set; }

VB.NET

Public Property GroupValueTemplate As DataTemplate

Property Value

Type	Description
DataTemplate	A DataTemplate object that defines the presentation of group values.

Remarks

The templates supplied by the DXGrid, allow you to completely replace the look and feel of visual elements while maintaining their existing behavior.

The binding source for the GroupValueTemplate template is represented by the GridColumnData class. Each column provides the GridColumn.GroupValueTemplate property that allows you to specify a custom template used to render its values displayed within group rows.

The code sample below shows how to bind to a row object’s Name property:

Xaml

<dxg:TableView.GroupValueTemplate>
    <DataTemplate>
        <TextBlock Text="{Binding RowData.Row.Name}" />
    </DataTemplate>
</dxg:TableView.GroupValueTemplate> 

The following code sample shows how to display values of several columns in a group row:

Xaml

<dxg:TableView.GroupValueTemplate>
    <DataTemplate>
        <TextBlock>
            <TextBlock.Text>
                <MultiBinding StringFormat="{}{0} - {1}">
                    <Binding Path="RowData.Row.Id" />
                    <Binding Path="RowData.Row.Name" />
                </MultiBinding>
            </TextBlock.Text>
        </TextBlock>
    </DataTemplate>
</dxg:TableView.GroupValueTemplate>
