Click event for controls under other controls

Question

I have two controls A and B. The B control is placed above A. When B is clicked, only the event with clicking on it fires, however I need to also click the A event to fire. Could this be implemented using routable events?

Here is a screenshot of the controls:

Of course, this case is just an example. I am looking for a general way to raise events on all controls under a mouse cursor / in one place. However, a concrete solution to this problem would also help me! Thanks so much for any hint!
