Remarks

MouseButtonEventArgs defines Handled, which is relevant for marking a mouse button event as handled. Handling the event prevents typical handlers further along the route from acting on the same event occurrence. For details on how to mark mouse events as handled, see Mouse Support.

In Silverlight, MouseButtonEventArgs does not carry information that reports which mouse button was clicked (left button or right button). If you want to know whether the mouse button was the left mouse button or right mouse button, you must use separate handlers for each event (UIElement.MouseLeftButtonDown and UIElement.MouseRightButtonDown).

Mouse events are sometimes promoted events from touch input stimulus. For more information about the concept of mouse event promotion, see Touch Input in Silverlight.
