anyone? idea??? thanx! tali

There is no visual inheritance in WPF. You should use a UserControl instead.

Edit:

<UserControl x:Class="MyUserControl">
  <StackPanel>
    <Button Content="Push me" Click="MyClickHandlerInUserControl" />
  </StackPanle>
</UserControl>

You can use this UserControl in any View e.g:

<Window x:Class="MyWindow"
     xmlns:uc="clr-namespace:MyNamespace.MyUserControls" >
  <StackPanel>
    <uc:MyUserControl /> <!--You can use any properties you have declared in your usercontrol -->
    <Button Content="Some other Button" Click="MyClickHandlerInWindow" />
  </StackPanel>
</Window>
