This GraphicsLayer contain graphics?  When you click on a graphic, the MouseLeftButtonDown does not get raised? I could not replicate it. Please share some code.

oth MouseLeftButtonDown and MouseLeftButtonUp do not work for that layer?
Yes. Two events don't work with that layer.

Is there maybe another MouseLeftButtonDown or MouseLeftButtonUp event that is marked Handled somewhere in your code? Could it be because there's no graphic where you clicked?
There is no another event in the page.

Can i send you my project , if needed !
