I have created an array of Nshapes, and I need to know when a Shape is selected with the right or the left mouse button. I have added this:

AddHandler DrawingView.EventSinkService.NodeSelected, AddressOf EventSinkServiceNodeSelected

This works but ONLY with the LEFT button. When I press the right button in a shape, that event is not fired.

I tried with this another:

AddHandler DrawingView.EventSinkService.NodeMouseDown, AddressOf EventSinkServiceNodeMouseDown

But it doesn't work AT ALL. I was seeing this page :

But I don't find the solution. Does anybody can help me ?
