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. For additional example code on grouping, see the Grouped GridView sample.


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

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


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



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

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



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;
