Remarks

A ContentControl has a limited default style. If you want to enhance the appearance of the control, you can create a new DataTemplate. For more information, see Data Templating Overview. Another typical scenario is to use the ContentControl to show more information about an item selected in an ItemsControl control. For more information, see How to: Bind to a Collection and Display Information Based on Selection.

Content Model: ContentControl is the class from which other content controls inherit. For more information on the content model for ContentControl, see Controls Content Model Overview.

Examples

The following example shows how to make a style for a ContentControl so that the control has an enhanced visual appearance.

<Style x:Key="ContentCtrl" TargetType="{x:Type ContentControl}">
  <Setter Property="Background" Value="Red"/>
  <Setter Property="Foreground" Value="Green"/>
  <Setter Property="FontSize" Value="20"/>
  <Setter Property="FontWeight" Value="Bold"/>
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type ContentControl}">
        <Grid>
          <!--Keep the Ellipse a circle when ContentControl.Width
              is set.-->
          <Ellipse Width="{TemplateBinding Width}"
                   Height="{TemplateBinding Width}"
                   Fill="{TemplateBinding Background}"/>
            <ContentPresenter VerticalAlignment="Center"
