Assembly: System.Web (in system.web.dll)
A data control field's view state is the accumulation of all its property values. To preserve these values across HTTP requests, ASP.NET server controls use this property, which is an instance of the StateBag class, to store the property values. The values are then passed as a variable to an HTML hidden input element when subsequent requests are processed. For more information about saving server control view state, see View State Overview.
View state is enabled for all server controls by default, but there are circumstances when you will want to disable it. For more information, see Developing High-Performance ASP.NET Applications.
