ATLAS UpdateProgressSignup: get a notification of UpdatePanel's events

UPDATE 03/09/2006: This post has a follow up, please read this for the updates.

One of the most asked questions on the ATLAS forums - one I asked myself just yesterday - is about how to get a notification when the UpdatePanels in the page perform their asynchronous postback to the server and moslty when they return their results.
If the UpdateProgress control does its work pretty well allowing to display a message during partial updates, someone may be interested in performing some custom actions when those events fire.

I don't want to delve into the mechanisms by which ATLAS performs its asynchronous calls and how the UpdateProgress subscribes to those events, for which I redirect you to the ATLAS forum, where it has been discussed largely like in this post.
Since the current ATLAS CTP doesn't provide us with an easy way of doing that I have created a server control which exposes two properties, which in turn accept the names of two Javascript functions you can write in your page and which are called respectively when the UpdatePanels initiate the postback and when the results are returned.

You can find more details and the download links here.

Hello, Simone: You are an angel! I've been trying to get my startup javascript (registered in the response to a partial postback) to do another partial postback in response to a javascript confirm dialog box. I've tried many techniques, but none have worked until I stumbled upon your UpdateProgressSignup control. It works like a charm. Thanks, Paul

With the new Atlas Toolkit released, you can wire up to partial update events.
