Override default style

Question

How can i override the default style of a control in SL ? So i dont have to do Style={...} in all Controls ...

In WPF

     <Style TargetType="Button">
            <Setter Property="Margin" Value="10"></Setter>
        </Style>

 

would put a Margin to all Buttons. What about SL ? 

 

Answer 1

 I had the same question, but they told me implicit Style is not available in SL.  See thread below:

You could subclass Button and define a new built-in style (in generic.xaml), but it hardly seems worth it just for the Margin.
