Saves the state of the properties in the Menu control that need to be persisted.
Assembly: System.Web (in System.Web.dll)
This method is used to save the state of the properties in the Menu control that need to be persisted, even when the EnableViewState property is set to false. The method is concerned with state data that is essential for a control's operation (such as an index or keyword) and is separate from the control's view-state data.
This method is used primarily by control developers to extend the Menu control.
