Example

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.

The following example demonstrates how to provide an implicit style targeting the HierarchicalGroupByControl class that changes the value of the NoGroupContent property to display Hello World rather than Drag a column header hear to group by that column..

XAML

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"

 xmlns:local="clr-namespace:Xceed.Wpf.Documentation">

  <Grid.Resources>

   <xcdg:DataGridCollectionViewSource x:Key="cvs_orders"

                                      Source="{Binding Source={x:Static Application.Current},

                                                Path=Orders}"/>

   <Style TargetType="{x:Type xcdg:HierarchicalGroupByControl}">

      <Setter Property="NoGroupContent"

              Value="Hello World" />

   </Style>

  </Grid.Resources>

  <xcdg:DataGridControl x:Name="OrdersGrid"

                      ItemsSource="{Binding Source={StaticResource cvs_orders}}"/>
