Examples

The following code example demonstrates how to bind a ListBox control to the results of a grouping LINQ query. In this example, a collection of teams is grouped by city and displayed with the city name as the group headers. For the complete code listing, see the XAML data binding sample.

<Grid>

 <Grid.Resources>
 <CollectionViewSource x:Name="groupInfoCVS" IsSourceGrouped="true"/>
 </Grid.Resources>

 <ListBox x:Name="lbGroupInfoCVS" 
 ItemsSource="{Binding Source={StaticResource groupInfoCVS.View}}">

 <ListBox.GroupStyle>
 <GroupStyle>
 <GroupStyle.HeaderTemplate>
 <DataTemplate>

 <TextBlock Text="{Binding Key}"/>

 </DataTemplate>
 </GroupStyle.HeaderTemplate>
 </GroupStyle>
 </ListBox.GroupStyle>

 <ListBox.ItemTemplate>
 <DataTemplate>

 <Border Background="{Binding Color}" 
 Width="200" CornerRadius="10" HorizontalAlignment="Left">

 <TextBlock Text="{Binding Name}" 
 Style="{StaticResource DescriptionTextStyle}" 
 HorizontalAlignment="Center" FontWeight="Bold"/>

 </Border>
 </DataTemplate>
 </ListBox.ItemTemplate>

 </ListBox>

</Grid>

Teams teams = new Teams();
var result = 
 from t in teams 
 group t by t.City into g 
 orderby g.Key 
 select g;
groupInfoCVS.Source = result;
