Example

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

The following example demonstrates how to group the data items by the ShipCountry and ShipCity columns.

XAML

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">
  <Grid.Resources>
    <xcdg:DataGridCollectionViewSource x:Key="cvs_orders"
                                    Source="{Binding Source={x:Static Application.Current},
                                                      Path=Orders}">       

     <xcdg:DataGridCollectionViewSource.GroupDescriptions>         
       <xcdg:DataGridGroupDescription PropertyName="ShipCountry"/>
       <xcdg:DataGridGroupDescription PropertyName="ShipCity"/>
     </xcdg:DataGridCollectionViewSource.GroupDescriptions>
    </xcdg:DataGridCollectionViewSource>
  </Grid.Resources>

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