Examples

The following example shows how to create and use a header template to specify the appearance of the header.

XAML

<!--Define a control template for a HeaderedItemsControl-->
<Style TargetType="HeaderedItemsControl">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type HeaderedItemsControl}">
        <StackPanel>
          <Grid>
            <Rectangle Fill="{TemplateBinding Background}"/>
            <ContentPresenter ContentSource="Header"/>
          </Grid>
          <Grid>
            <Rectangle Stroke="{TemplateBinding BorderBrush}"/>
            <ItemsPresenter Margin="2,0,0,0"/>
          </Grid>
        </StackPanel>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

XAML

<DataTemplate x:Key="RedHeaderTemplate">
  <TextBlock Text="{Binding}" Foreground="Red" 
             FontSize="16" FontWeight="Bold" 
             TextWrapping="Wrap"/>
</DataTemplate>

<DataTemplate x:Key="GreenItemTemplate">
  <TextBlock Text="{Binding}" Foreground="Green" 
             FontSize="14" FontWeight="Bold"></TextBlock>
</DataTemplate>

XAML

<!--Crate a HeaderedItemControl with a red header and green items.-->
<HeaderedItemsControl Name="hitemsCtrl"  
                      Background="DarkBlue" 
                      BorderBrush="Black"
                      Header="Header"
                      HeaderTemplate="{StaticResource RedHeaderTemplate}"
                      ItemsSource="{Binding Source={StaticResource Numbers}}"
                      ItemTemplate = "{StaticResource GreenItemTemplate}" />

Remarks

Because the Header property is of type Object, there are no restrictions on what you can put in the Header. The Header is displayed by a ContentPresenter, which is in the HeaderTemplate of the HeaderedItemsControl. For more information about how the ContentPresenter displays the Header, see ContentPresenter.
