wpf eventsetter handler binding in style

Question

I have a style, and I want to bind a command to the EventSetter\'s Handler with RelativeSource. The command is in the viewModel.

Answer 1

My answer on this question does the trick without any external tool kits/libraries. However, it does not use RelativeSource, and it is not 100% MVVM. It requires one line of code in a code-behind event handler.
