Control Base. Exiting Event
Occurs when the user clicks outside the content control, or when the cursor is moved outside the content control programmatically.
event Microsoft.Office.Tools.Word.ContentControlExitingEventHandler Exiting;
If the content control is nested inside another content control, the Exiting event is raised only for the nested control, not the parent control. For example, if the user clicks outside a PlainTextContentControl that is nested in a GroupContentControl, this event is raised only for the PlainTextContentControl; this event is not raised for the GroupContentControl.
