AJAX UpdatePanel fails to load in IIS 8.5 (Windows server 2012) RRS feed

  • Question

  • User2072204415 posted

    Problem Statement When an event is fired, the updateprogress runs indefinitely and the update panel is not refreshed or the request does not end in IIS 8.5 (Windows Server 2012).

    Migrating application from .net 3.5 to .net 4.5.2. The server has only .net 4.5.2 installed. It works perfectly in my local VS 2013 and also have been running perfectly in IIS 6.5 and Windows server 2003.

    What could be the issue ? What am I missing ?

    What could be the issue ?

    We can only guess.  I assume you are updating the target framework and moving the app to a new server?

    What am I missing ?

    Troubleshooting and debugging? 

    Open dev tools (F12) and look for errors in the console and network tab.  Can we assume everything is working except the update panel on one page? What is the updatepanel doing?  Updating a DB table?  Check connection string?  Are you sure the new server is configured correctly?

    Can you tell us what troubleshooting steps you have performed up to this point?
