StateManagedCollection.IStateManager.TrackViewState Method ()
Assembly: System.Web (in System.Web.dll)
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 life cycle. For more information, see NIB: ASP.NET Web Server Controls.
