I have a problem designing custom made buttons. After a lot of effort with (not working) XAML tools I tried overwriting the Control class to design own controls / buttons. While it works very fine with a Windows Application it does not with the Windows Embedded Compact SDK. Everything is similar and there is no problem to register the "MeinSteuerelement" class, but only in the Win App it's usable while in the WCE environment the class is shaded.
Where could be my mistake? Isn't it possible in WCE to override classes?
