Mouse event not reaching UIElement

문제
I have a 6x8 grid of System.Windows.Controls.Canvas
objects. The top left canvas does not receive mouse events while all the others do. I tried OnMouseMove
and OnMouseClick
events.
A child object isn't handling the event because System.Windows.Media.VisualTreeHelper#GetChildrenCount()
doesn't show any children. I couldn't catch PreviewOnMouseMove
either. Can there be some (perhaps transparent) control in front of my canvas that is taking precedence?

Finally found a solution. Each of the Canvas
es have Adorner
s. According to this MSDN article, adorners receive mouse events before the underlying UI element does. I set the IsHitTestVisible
property of all my adorners to false
.

I hope this helps you, Just set Transparent
value to the Background
property for the Canvas
:
Background="Transparent"
Good luck!
