My company bought the RadControls for asp.net and the first time I have tried to use any of the controls after a uneventful and successful install I get this error:
Error 1 Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. Z:\ClosingApp\Default.aspx 14 
What is causing this error?

Hello,

I assume that Z: drive is a mapped network share, is that correct? The .NET Code Access Security (CAS) disallows executing code from the intranet zone by default. You should either move the application to a local drive or modify the CAS policy.

Refer to this KB for more information:
