Gets or sets whether RichEditControl should be disposed of when a window is closed.
false, to prevent RichEditControl from being disposed of when a Window is closed; otherwise, true. Default is true.
By default, the RIchEditControl is disposed of when a window is closed. This behavior is implemented due to the RichEditControl's internal structure specifics. If you have a reason to retain a RichEditControl instance and re-use it after a window is closed, set the HandleWindowClose to false. Consider possible memory leaks in this situation.
You can destroy the control manually by calling the RichEditControl.Dispose method.
