Update Panel is not working in SharePoint 2013. It is working in SP2010. In Internet Explorer, it is working fine but in Firefox, the page is refreshed.

1 Answer 1


There appears to be some sort of change in the postback mechanism that's used by SharePoint and ASP.NET in SP2013.

Here's a solution provided on MSDN

In Visual Studio, add a reference to Microsoft.Practices.SPG.AJAXSupport.dll. Add a SafeScriptManager control to your page and set the EnableUpdatePanelSupport flag to true. This changes the postback script that is needed for the UpdatePanel control to work in a SharePoint environment. The following code demonstrates how to add a SafeScriptManager control to a page.
