I want to check the role of the user if it is an administrator only then the user can see the link to user control.when i try to run this code it is giving me an error saying "'Data.User' does not contain a definition for 'IsInRole'"

I don't believe the ViewUserControl type has a User property, so the compiler thinks you're trying to access your domain object of type Data.User. In a partial control, you can access the User instance using HttpContext.Current.User where the IsInRole method should work.
