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 Label.LoadViewState(object) method restores view-state information for the System.Web.UI.WebControls.Label control from a previous page request that was saved by the WebControl.SaveViewState method.
