Is this possible to override method of sealed class?

In WinRT(C#, xaml) ScrollViewer - is sealed class, and I can't extend it, but I need to overwrite some methods (for ex: ScrollToHorizontalOffset). Is this possible to override method of sealed class?

No - in order to override a method, you have to derive from it, which you can't do when the class is sealed.

Basically, you need to revisit your design to avoid this requirement...
