I read the gave link on your replies before sending the post. Fortunately, I found a suggestion to comment out this "
<addkey="Telerik.ScriptManager.TelerikCdn"value="Enabled" /> " in web.config and it works
If you have an explanation that will help my understand.
Kind Regards,
Duy

Hello Duy,
When CDN is enabled skins and scripts are cached by browser and this helps to improve the loading speed of the pages with RadControls for ASP.NET AJAX. For more information about Telerik CDN you can refer to the article below: http://www.telerik.com/help/aspnet-ajax/stylesheetmanager-cdn-support.html
