Publisher review:Modal Progress Dialog allows you to show a modal progress dialog for any ajax operation. If you ever like to show a modal progress dialog for any ajax operation no matter which Update Panel or Web Service call is responsible for it, this script will do the same.
The main trick is hooking the two special events of Sys.Net.WebRequestManager class. This class is responsible for managing all kinds of communication with the server, even a manual invoke of a Sys.Net.WebRequest class will bring this class into action.
It fires the invokingRequest before making an Ajax call and fires the completeRequest once the method completes. We are simply showing/hiding the modal popup extender in these events.
