Hello masha reznik,
I am not sure if I understood you correctly. I suppose that you want to perform some DragDrop functionality using MouseRightButtonClick. If so the you can try the following:
this.AddHandler(FrameworkElement.MouseRightButtonDownEvent, new MouseButtonEventHandler(Window1_MouseRightButtonDown), true);
private void Window1_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
//StartDrag or some other custom logic here....
I hope that this will help you. Please let us know if you have any other questions or need some more help.
