Can I have one Style with multiple TargetType in WPF?

Question

As titled, and I mean something like below:

<Style TargetType="{x:Type TextBlock}" 
       TargetType="{x:Type Label}"  
       TargetType="{x:Type Button}" >

This is actually for the sake of using a 3rd party control, I have inherited their class. But the template doesn't apply to the SubClass because the TargetType is on the base class. So I would like to set multiple TargetTypes to make it able to apply for both.

No you cannot, however I often create a style for a shared base class such as FrameworkElement, and then create my individual control styles that are BasedOn the base style

<Style TargetType="{x:Type FrameworkElement}">
    <!-- Shared Setters -->
</Style>

<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type Label}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
