As both extenders are from the ASP.NET AJAX Control Toolkit (once Microsoft, today DevExpress) both need the special script-manager comes with the package...
However! There were several problems with that script-manager so it has been removed since version 15.1 - use that version or newer and your script-manager problem will be gone...
