Defines the properties and methods any class must implement to support view state management for a server control.
See Also: IStateManager Members
A server control's view state comprises the cumulative values of the control's properties. This interface includes methods that save and load a server control's view state values, as well as a method that instructs the control to track any changes to its view state.
To customize the way your ASP.NET application manages server control view state, you must create a class that implements this interface because you cannot inherit from the System.Web.UI.StateBag class.
