One Update Panel vs. Multiple Update Panels

I have an ASP.NET web page that displays a variety of fields that need to be updated best on certain conditions, button clicks and so on. We've implemented AJAX, using the ASP.NET Update Panel to avoid visible postbacks.

Originally there was only one area that needed this ability ... that soon expanded to other fields. Now my web page has multiple UpdatePanels.

I am wondering if it would be best to just wrap the entire form in a single UpdatePanel, or keep the individual UpdatePanels.

What are the best practices for using the ASP.NET UpdatePanel?

I'd caution that with multiple update panels you'll want to be careful. Make sure you set the UpdateMode to Conditional. Otherwise, when one update panel is "posted back" to the server, all of them are posted back.

I'd highly suggest using these tools

Web Development Helper (here's a brief tutorial Web Development Helper and ASP.NET Ajax)

Fiddler
