lost skin after long idle

[Anthony]

I encountered a strange problem for my working project. I have a menu on the top of the page using custom theme. But if I the page is set idle for 20 minutes it will log out which is correct. However if I log back on, the menu will lost the style and shows as hyperlinks. Also I will receive a error message "Microsoft JScript runtime error: Sys.ScriptLoadFailedException: The script  could not be loaded." If I refresh the page, then everything will be fine. Does anyone had similar problem and I really appreciate if you can help me to solve this.

Hi Anthony,

You can experience this problem after an application restart. The titlebar and border images are loaded from the embedded resources in the Telerik.Web.UI.dll, and have dynamic urls. When the application is restarted, the web browser is trying to load the old invalid paths to the embedded resources, and not the newly generated ones.

You can easily fix this browser caching problem, by registering the skins and scripts from a CDN server or the external skins and scripts of the control which have fixed paths.

Detailed information how to register scripts and skins using CDN is available in the following blog post:
CDN Support – RadControls for ASP.NET AJAX
Tutorial on how to register external skin is available in the Appearance section of the documentation for each control.
