This documentation is for a previous version. For the current released version, see the ASP.NET Ajax documentation on MSDN.










Raised by the Microsoft AJAX Library when a call to a method has failed, but the reason was not invalid arguments.


When a client function or method is called and an error occurs that is not caused by invalid arguments, a Sys.InvalidOperationException object is created by using the Error.invalidOperation function.

For more information about how to raise this error, see invalidOperation Function.

For more information about how to handle error conditions, see ASP.NET AJAX Debugging and Tracing Overview.
