Ignore element for touch events in WPF

Question

I have a Window with two Image elements: Back and Front. Obviously, Front has higher Z-index then Back. I also have TouchMove handler on Back. But the event is not triggering when Back is overlapped with Front in the touch point. So, how do I make touch to ignore Front?

Answer 1

If you want touch or click events to fall through to an underlying control, set IsHitTestVisible to false on the Front Image.

Here's more information on how hit testing works on UIElements.
