This property defaults to False. When set to False, the editor will exit edit mode when the control looses focus and re-enter edit mode when it receives focus. As a result it will also raise the EditModeStarting, EditModeStarted, EditModeEnding and EditModeEnded events.
If you set this property to True, the editor will always remain in edit mode. However note that this property is ignored when the editor is embedded inside another control (i.e. is hosted inside a ValuePresenter). When it's embedded, it will exit edit mode as directed by the hosting control.
