The System.Web.UI.IStateFormatter interface defines methods that a type can implement to serialize and deserialize the state that an ASP.NET Web server control maintains in its Control.ViewState property. This infrastructure is used by classes that derive from the System.Web.UI.PageStatePersister class to maintain an ASP.NET page's state between requests. By default, ASP.NET page state is serialized and deserialized by an instance of the System.Web.UI.ObjectStateFormatter class; however, site and adapter developers can implement the System.Web.UI.IStateFormatter interface on their own types to perform this work.
