Hello Omar Mohammad,

Please, check whether your web.config file contains references to older version of RadControls for ASP.NET AJAX.
Also checkout the following documentation which describes about the same issue and resolution.
General Troubleshooting
Error: Could not load file or assembly

I hope the following link would help in upgrading to new version: Upgrading RadControls Trial to RadControls Developer license or newer version

Thanks,
Shinu.
