The Object that contains the changes to the HotSpot object's view state. If no view state is associated with the object, this method returns null.
Remarks
The SaveViewState member is used primarily by control developers when deriving a custom implementation from the HotSpot class.
View state is the accumulation of the values of a server control's properties. These values are automatically placed in the server control's ViewState property, which is an instance of the StateBag class. This property's value is then persisted to a string object after the save state stage of the server control's life cycle. For more information, see ASP.NET Application Life Cycle Overview for IIS 5.0 and 6.0.
When view state is saved, this string object is returned to the client as a variable that is stored in a hidden HTML input element. When you author custom server controls, you can improve efficiency by overriding this method and modifying your server control's ViewState property. For more information, see ASP.NET State Management Overview.
