The June CTP of Atlas is out
This new CTP is mainly bug fixes, but there are a few additions on UpdatePanel which should make your day if you've hit some of the caveats Matt and I talk about in our booklet on UpdatePanel.
In previous CTPs, UpdatePanels had to be created very early in the page lifecycle so that they could participate in this lifecycle efficiently. This made it almost impossible under reasonable circumstances to dynamically create UpdatePanels. For example, most scenarios where an UpdatePanel was inside another control's template were failing.
Well, now it works!
Nikhil has an interesting post where he explains this change in great details, how it happened and a couple of interesting scenarios it opens up:
We'll update the O'Reilly PDF document soon to reflect those changes... I'll keep you posted.
