can do this using:

        // Custom property used for dropdowns.
        public virtual System.String DropdownName
        {
            get
            {
                return _lastname + ", " + _firstname;
            }
        }

and creating a custom method which wraps the relevant stored proc and feeds the user entity with a collection of teamleaders.

question: can the flixon generator be run against sql server 2000? i'm getting a 'stored procedure not found' error.
thanks.
