LINQ multiple sort (nested)

I have a LINQ method that gets called from User Control

and dumps straight to standard DataGridView

. My users want it to be sorted by default, first DisenrollmentDate

, and then Member Name

. Right now, with the code below, it is only sorting DisenrollmentDate

.

BLLCmo.cs

    public static DataTable GetAllMembers(Guid workerID)
    {
        var AllEnrollees = from enrollment in context.tblCMOEnrollments
                               where enrollment.CMOSocialWorkerID == workerID || enrollment.CMONurseID == workerID
                               join supportWorker in context.tblSupportWorkers on enrollment.EconomicSupportWorkerID equals supportWorker.SupportWorkerID into workerGroup
                               from worker in workerGroup.DefaultIfEmpty()
                               orderby enrollment.DisenrollmentDate ascending 
                               select new
                                       {
                                           enrollment.ClientID,
                                           MemberName = BLLConnect.MemberName(enrollment.ClientID),
                                           NurseName = BLLAspnetdb.NurseName(enrollment.CMONurseID),
                                           SocialWorkerName =BLLAspnetdb.SocialWorkerName(enrollment.CMOSocialWorkerID),
                                           enrollment.DisenrollmentDate,
                                           enrollment.EnrollmentDate,
                                           ESFirstName = worker.FirstName,
                                           ESLastName = worker.LastName,
                                           ESPhone = worker.Phone
                                       };

        var dataTable = AllEnrollees.CopyLinqToDataTable();

        return dataTable;
    }

      

        
        
        
      

    

BLLConnect.cs

    public static String MemberName(Int32 personID)
    {
        var memberName = from person in context.tblPersons
                         where person.PersonID == personID
                         orderby person.LastName ascending 
                         select person.FirstName + " " + person.LastName;

        return memberName.SingleOrDefault();
    }
