Role management without provider?

In my application, I need to check the roles for the loggind user to determine if the user can see some controls or not.

at first I use the loginview template from MS, but since I have no db users, no db roles, therefore, I could not add a role provider, so I could not use the Role class to check users \ role

As in my case, I have a session with information about the user and his roles, and I need to check these roles to determine which control will be enabled for the user, but with the standard way "using .net built into the class or code "
