    There is no shadow in your style that can be displayed, so it is not displayed. Add shadow rendering and show it. You can do this, for example, like this: first, we set the outer margin of Margin so that our shadow is not clipped during the output:

     <Border x:Name="border" Margin="10" ...

    Now let's replace the code in the trigger:

     <ControlTemplate.Triggers> <Trigger Property="HasDropShadow" Value="True"> <Setter Property="Effect" TargetName="border"> <Setter.Value> <DropShadowEffect Color="Red" /> </Setter.Value> </Setter> </Trigger> </ControlTemplate.Triggers>
