When use ajax control toolkit in dotnetnuke have errors:

A critical error has occurred.
The control with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

Help me!

Thank you!

I did a clean install of DNN4.8.2 yesterday and installed my ajax module yesterday. Everything was working like it should the DNN progress image was showing when processing. When I accessed the module this morning I was getting the above mentioned error. I have not changed anything in the dotnetnuke or server environment. I had to add the scriptmanager tags manually to get the module to atleast function. Could someone please help me, or to point me in a direction to start trouble shooting?

Thanks in advance

We put this in our modules to make sure Ajax works correctly

To the OP, if you're getting errors, be sure you're on 4.8.2 as there is a pretty big bug fix for Ajax issues in 4.8.2

EDIT: cleaned up formatting issue with code

        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);
            if (DotNetNuke.Framework.AJAX.IsInstalled())
            {
                DotNetNuke.Framework.AJAX.RegisterScriptManager();
            }           
        }
