Ajax Question

[Microsoft Newsserver]

I am running ASP.NET 2.0 with Ajax.


I am invoking an asyncronous postback by invoking a button click which
triggers the async postback. This works fine, but I need to take into
consideration the success or not of the request.


//Pseudo Code.


__doPostBack( 'btnMyButton.......

alert('Thank you, your request has been completed');


OK, no what is happening of course is that the alert pops up before the
relative update panels are updated on the client.

I need to be able to

a.) Sync my 'Thank You' Message with the reuest being complete.
b.) Take into consideration that a timeout may occur.


Any constrcutive suggestions to do this would be greatly appreciated.

Thanks ....
