Avoid using of UpdatePanel.


The ASP.NET AJAX UpdatePanel control must change the page’s postback behavior to enable support for asynchronous postbacks and partial rendering. However, in a SharePoint application, these modifications cause a JavaScript error. This is because SharePoint attempts to make a similar change.

Here are couple problems with UpdatePanel usage in the SP2010 and SP2007:
  1. Webpart and AJAX – second postback not working in UpdatePanel?
  2. Problem with only first postback working in Chrome from UpdatePanel in Sharepoint site


When possible try to avoid using of UpdatePanel, preferring jQuery.ajax() instead.
