WPF: Canvas swallowing MouseDownEvent?

Question

Can anybody please explain to me why theMouseDownevent is not reaching theScrollViewerin this easy example?

Answer 1

You will probably need to set Focusable="False" on the ScrollViewer to allow the mouse events to pass though

 <ScrollViewer Name="scrollViewer" Focusable="False" Background="Green" />

Output:

ScrollViewer_PreviewMouseDown
Canvas_PreviewMouseDown
Canvas_MouseDown
ScrollViewer_MouseDown
