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

 


Output:

ScrollViewer_PreviewMouseDown
Canvas_PreviewMouseDown
Canvas_MouseDown
ScrollViewer_MouseDown

    
             
                                                        
            
            
              
                
                0
