The SelectionTree control uses the SelectionNoItems event to delete obsolete item description text or to disable buttons that have become useless. This event should be authored in the EventMapping table.

This ControlEvent requires the user interface to be run at the full UI level. This event will not work with a reduced UI or basic UI. For information, see User Interface Levels.
