IStateManager Interface


Defines the properties and methods any class must implement to support view state management for a server control.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

type IStateManager = interface end


When implemented by a class, gets a value indicating whether a server control is tracking its view state changes.


When implemented by a class, loads the server control's previously saved view state to the control.


When implemented by a class, saves the changes to a server control's view state to an Object.


When implemented by a class, instructs the server control to track changes to its view state.

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 StateBag class.

The following code example shows a class that implements the IStateManager interface. It includes implementations of the IsTrackingViewState property and the LoadViewState, SaveViewState, and TrackViewState methods.

No code example is currently available or this language may not be supported.
