Examples

The following example creates a TabControl that contains two TabItem objects, which inherit from HeaderedContentControl. The first TabItem has UIElement objects as the content in both the Header and the Content: the Header is set to a StackPanel that contains an Ellipse and a TextBlock; the Content is set to a StackPanel that contains a TextBlock and a Label. The Header of the second TabItem is set to a string and the Content is set to a single TextBlock.

<TabControl>
  <TabItem>
    <TabItem.Header>
      <StackPanel Orientation="Horizontal">
        <Ellipse Width="10" Height="10" Fill="DarkGray"/>
        <TextBlock>Tab 1</TextBlock>
      </StackPanel>
    </TabItem.Header>
    <StackPanel>
      <TextBlock>Enter some text</TextBlock>
      <TextBox Name="textBox1" Width="50"/>
    </StackPanel>
  </TabItem>
  <TabItem Header="Tab 2">
    <!--Bind TextBlock.Text to the TextBox on the first
    TabItem.-->
    <TextBlock Text="{Binding ElementName=textBox1, Path=Text}"/>
  </TabItem>
</TabControl>

The following illustration shows the TabControl created by the previous example.

TabControl with different types in the Header property

The following example creates two DataTemplate objects to specify the appearance of the Header and Content of the HeaderedContentControl.


<Style TargetType="HeaderedContentControl">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type HeaderedContentControl}">
        <StackPanel>
          <Grid>
            <Rectangle Stroke="{TemplateBinding Background}"/>
            <ContentPresenter ContentSource="Header"/>
          </Grid>
          <Grid>
            <Rectangle Fill="{TemplateBinding Background}"/>
            <ContentPresenter ContentSource="Content"/>
          </Grid>
        </StackPanel>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

<DataTemplate x:Key="titleText">
  <TextBlock Text="{Binding}" 
             Foreground="Green" 
             FontSize="16" 
             FontWeight="Normal"
             FontStyle="Italic" 
             TextWrapping="Wrap"/>
</DataTemplate>

<DataTemplate x:Key="contentText">
  <TextBlock Text="{Binding}"
             Foreground="Brown"
             FontSize="12"
             FontWeight="Normal"
             FontFamily="Arial Narrow" 
             TextWrapping="Wrap"/>
</DataTemplate>

<HeaderedContentControl Name="hcontCtrl" Background="Beige" 
                        HeaderTemplate="{StaticResource titleText}" 
                        ContentTemplate="{StaticResource contentText}"
                        Header="This is the header."
                        Content="This is the content."/>

Remarks

Like the Content property of a ContentControl, the Header can be any type. The HeaderedContentControl uses the same logic to display the Header that is described in ContentControl.Content.
