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