WPF/C# inherit style

Hello you all,

I would like to create a special button that inherit from Button in c#. This button has a special behavior, that's why I just can't apply a template on it.

So, I created my SpecialButton class, wrote the code and inserted it in my window... Doing this, I expected that the SpecialButton will adopt its "mother" 's style. But the SpecialButton does not want to hear anything it does not inherit its mother style.

I believe that it is due to the fact that I defined a style for {x:Type Button}.

How can I say to my special button that for the style he IS a Button???
I hope that my explanations are clear enough:s.

Thanks.
