Raised by the Microsoft Ajax Library when a requested method is not supported by an object.
When an attempt is made to call a client method that is not supported by an object, a Sys.NotImplementedException object is created by using the Error.notImplemented function. Typically this exception is thrown from the function body of an abstract method declaration or from an interface method declaration.
For more information about how to raise this error, see Error.notImplemented Function.
