Template Switching - Extend with DataTemplate assigned to type

[dhcgn]

Often we want to switch the template depending to the type of the binding object.

<DataTemplate DataType="{x:Type MyObject}">
   <StackPanel Orientation="Horizontal">
      <StackPanel.Resources>
         <DataTemplate DataType="{x:Type Thing1}">
            <Image Source="thing1.png"/>
         </DataTemplate>
         <DataTemplate DataType="{x:Type Thing2}">
            <Image Source="thing2.png"/>
         </DataTemplate>
      </StackPanel.Resources>
      <ContentPresenter Content="{Binding A}"/>
      <TextBlock Text="{Binding Text}"/>
   </StackPanel>
</DataTemplate>
