AddHandler(UIElement,RoutedEvent,Delegate) Method

Adds an event handler for a routed event.

Remarks

If other handlers exist for the event, the handler added with AddHandler is called first.

To add a handler for a routed event, use AddHandler(UIElement,RoutedEvent,Delegate). To add a handler for a non-routed event, use AddHandler(UIElement,String,Delegate). Check the event documentation in MSDN to determine whether it is routed or not.

Handlers added with this method are released by the UFT infrastructure.
