I've seen a few different posts about this, but they are mostly outdated and didn't resolve my issue. I put together some simple steps we took to make it work.
We had a project that originally used the AjaxControlToolkit on some pages. All new development used Telerik controls. There were issues performing Ajax operations despite the AjaxControlToolkit not even being registered on a page. This was the only fix I could find.
- Remove the existing
AjaxControlToolkit reference from the project and delete the
AjaxControlToolkit.DLL from the bin directory on the remote server (if it
exists)
- Remove any
AjaxControlToolkit assembly registrations at the top of the page markup
(if they exist)
- Install the
AjaxControlToolkit via the NuGet package manager in Visual Studio (update
the tag prefix as needed)
- In the MasterPage markup, disable combining scripts in
the RadScriptManager
<telerik:RadScriptManager runat="server" ID="RadScriptManager1" EnableScriptCombine="false"></telerik:RadScriptManager>
I hope this helps someone else down the road. A better solution is to replace the AjaxControlToolkit controls with Telerik controls, but this gets us by until we make time to do that.

Thank you for sharing your way of using the AjaxControlsToolkit along with Telerik AJAX controls.
I just wanted to add that Telerik UI for ASP.NET AJAX does not support officially the AjaxControlsToolkit and you may experience interoperability problems as explained in this article: Telerik controls are incompatible with Ajax Control Toolkit.
