Parameter.System.Web.UI.IStateManager.SaveViewState Method

Note: This method is new in the .NET Framework version 2.0.

This method supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Saves the changes to the Parameter object's view state since the time the page was posted back to the server.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

Object IStateManager.SaveViewState ()
J# supports the use of explicit interface implementations, but not the declaration of new ones.
JScript supports the use of explicit interface implementations, but not the declarations of new ones.

Return Value

The Object that contains the changes to the Parameter object's view state. If there is no view state associated with the object, this method returns a null reference (Nothing in Visual Basic).

This method is used primarily by control developers.

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.

When view state is saved, this string object is returned to the client as a variable that is stored in an HTML hidden element. When you author custom server controls, you can improve efficiency by overriding this method and modifying your server control's ViewState property.
