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

                      BorderBrush="Black"
                      Header="Header"
                      HeaderTemplate="{StaticResource RedHeaderTemplate}"
