I have a newly upgraded application at www.cougarsbaseballsoftball.com that works fine on IE and Chrome on a PC but is failing on Safari and Chrome on iOS8 devices. On pageload it fails producing the message, “The control with ID upnlMessage (an update panel) requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.”

The scriptmanager, a version provided, via the AJAX control toolkit, is in the masterpage: All of the script references go here…

    </ajaxToolkit:ToolkitScriptManager>

I have tried the following solutions from related posts but have not found a workable solution:

1.Create an App_Browser file to handle requests from iPads: iPad 6_0_1 ScriptManager.SupportsPartialRendering ASP.Net. This did not correct the iOS inter-op issue, but caused no impact to browsers on PCs. This change was rolled-back. 2. Create an App_Browser file to handle requests for Safari browsers (presumably across platform): iOS 8 / Safari 8 not working with ASP.NET AJAX-Extensions. This did not correct the iOS inter-op issue. It caused application failure on the PC browsers. This change was rolled-back. 3. Add EnablePartialRendering and LoadScritsBeforeUI attributes to the ToolkitScriptManager declaration (see above) - The ScriptManager must appear before any controls that need it - Chris Bint’s point near the bottom. This change was left in the application.

The site is running on a GoDaddy Ultimate site with trust level = full. Although the site is running on framework 4.5.1 the problem can be replicated on 4.5.0. I have not tried to revert to 4.0 due to interdependency issues with the Ajax Control Toolkit.

Check to see if you have a Site.Mobile.master and a ViewSwitcher.ascx in your solution.

I ran into this problem and discovered that when trying to view the application on a mobile device it was actually switching to the mobile master which didn't have a script manager. I am using a responsive web design and decided to exclude the mobile master and ViewSwitcher which solved my problem.

Hope this will work for you as well.

Happy New Year.

Yes, my error. First responsive application so I did not consider Site.Mobile.Master. I put in redirect code to by pass it's use in the onLoad() event; However, I still needed to put the Ajax Control Toolkit script manager in the Site.Mobile.Master page to avoid the error.

Thanks for your help!
