This method is used primarily by the .NET Framework infrastructure and is not intended to be used directly from your code. However, control developers can override this method to specify how a custom server control restores its view state. For more information, see ASP.NET State Management Overview.
The LoadViewState method restores the view-state information that was saved during a previous SaveViewState request. The WebControl class overrides the base LoadViewState method to handle the ViewState, Style, and Attributes properties.
