#590 – Not All Routed Events Exist in Pairs

Many of the routed events defined for common user interface elements in WPF exist in pairs–with an Xyz event that is bubbling and a corresponding PreviewXyz event that is tunneling.  But there are also many routed events that exist without a corresponding paired event.

For example, the Click event, defined in ButtonBase is a routed event that is a bubbling event.  When a user clicks on a Button, the Click event fires on the Button and then propagates up the logical and visual trees.
