Telerik ASP.NET UI Controls Update to 2013 Q3 causing errors

[Andy]

We recently upgraded our telerik control to the version 2013 Q3 and from then our web pages are broken. We do get the error

Could not find UpdatePanel with ID "". If it is being updated dynamically then it must be inside another UpdatePanel.

There have been no changes made on our page and this error comes only after the upgrade. If i revert the telerik control dll version to the old one they start working fine.

Hello Andrew,

Such error could be observed if there are nested AJAX settings on the page or if you are trying to ajaxify controls which are not initially visible on the page.

However, since you are confirming that the same page is working correctly with previous version, could you please elaborate what was your previous version of our controls. Furthermore, provided the markup and the code-behind of the page could help us locate the root of the problem in your project.

Listed bellow you could find another forum threads regarding the same issue:

• Sys.InvalidOperationException: Could not find UpdatePanel with ID
• Sys.InvalidOperationException: Could not find UpdatePanel with ID If it is being updated dynamically then it must be inside another UpdatePanel
• Could not Find Update Panel ID

I am looking forward to your reply.
