ASP.NET AJAX behaviors and controls have a common event signature:

  • The first parameter is a reference to the ASP.NET AJAX control or behavior that raised the event.

  • The second parameter is an arbitrary complex type.

You could create a custom event delegate to provide this functionality. Because this is a common need, the ScriptEventHandler class is provided as a convenience.
