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

public:

	Object^ get ();
	void set (Object^ value);
}

Property Value

Type: System::Object
An object that contains view state data.

View state is a dictionary of state data that Web server controls need to function and render themselves. Control developers typically access the view state object using the ViewState property. View state is affected when view state is disabled at the Page level, and as a result controls might not behave correctly in these scenarios. For more information on using ViewState and control state when developing controls, see Developing Custom ASP.NET Server Controls.

The following code example demonstrates how a class that derives from the PageStatePersister class initializes the ViewState property. In this example, the ViewState property has been assigned to the First field of a Pair object, and serialized using the ObjectStateFormatter object, which is an instance of the IStateFormatter interface. When the Load method is called, the ObjectStateFormatter interface is used to deserialize view state information, and the ViewState property is initialized from the resulting Pair object's First field. This code example is part of a larger example provided for the PageStatePersister class.
