ChangePassword.SaveControlState Method ()
Saves any server control state changes that have occurred since the time the page was posted back to the server.
Assembly: System.Web (in System.Web.dll)
Notes to Inheritors:
When control state is saved, a string object is returned to the client as a variable that is stored in an HTML <input type="hidden" /> element. Override the method to extract the state information to use in the ChangePassword control.
Control state is intended for small amounts of critical data, such as a page index or a keyword. Using control state for large amounts of data can adversely affect page performance.
