Is there a way to trap the MouseLeftButtonDown event on a transparent background in WPF?

Question

I build a WPF UserControl. This control has a transparent background. I want to trap the MouseLeftButtonDown event, even when this event happens on the transparent background. If I change the background to "White", or another color, the event is trapped as expected.

Is there a way to tell the control to listen for the event, even if it happens over a transparent area?

Thanks.

There is a difference in specifying no Background and specifying a transparent background: {x:Null} vs. Transparent?

You're right. I was not specifying a background. When I specified Background="Transparent", it worked perfectly. Thank you. – Sako73 Apr 12 '11 at 14:11
