<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:DataGridCollectionViewSource.GroupDescriptions> </xcdg:DataGridCollectionViewSource> </Grid.Resources> <DockPanel> <Button Content="Export" Click="ExportButton_Click" DockPanel.Dock="Top" /> <xcdg:DataGridControl x:Name="OrdersGrid" ItemsSource="{Binding Source={StaticResource cvs_orders}}"/> </DockPanel> </Grid>

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

        <xcdg:DataGridCollectionViewSource.GroupDescriptions>

           <xcdg:DataGridGroupDescription PropertyName="ShipCountry" />

        </xcdg:DataGridCollectionViewSource.GroupDescriptions>

     </xcdg:DataGridCollectionViewSource>

  </Grid.Resources>

  <DockPanel>

     <Button Content="Export"

             Click="ExportButton_Click"

             DockPanel.Dock="Top" />

     <xcdg:DataGridControl x:Name="OrdersGrid"

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

  </DockPanel>

</Grid>

VB.NET	Copy Code
Private Sub ExportButton_Click( ByVal sender As Object, ByVal e As RoutedEventArgs ) Dim exporter As New ExcelExporter( Me.OrdersGrid ) exporter.GroupHeaderFormat.MultipleItemsFormat = "The {1} group contains {2} items." exporter.GroupHeaderFormat.SingleItemFormat = "The {1} group contains 1 item." exporter.Export( "d:\orders.xls" ) End Sub

VB.NET

Copy Code
