다음 예제에서는 사용 하는 방법의 HeaderTemplate 속성:The following example shows how to use the HeaderTemplate property:


<ListBox Name="Master" Grid.Row="2" Grid.ColumnSpan="3" Margin="8"
    ItemsSource="{Binding Source={StaticResource listingDataView}}">
    <ListBox.GroupStyle>
        <GroupStyle 
          HeaderTemplate="{StaticResource groupingHeaderTemplate}"
          />
    </ListBox.GroupStyle>
</ListBox>

다음은 정의 된 groupingHeaderTemplate DataTemplate:The following is the definition of the groupingHeaderTemplateDataTemplate:

<DataTemplate x:Key="groupingHeaderTemplate">
    <TextBlock Text="{Binding Path=Name}"
               Foreground="Navy" FontWeight="Bold" FontSize="12"/>
</DataTemplate>
