        {

            ComponentsDataContext db = DBManager.DataContext;

            var sch_view_class_student_list = (from even in db.sch_view_parent_student_search_lookup

                                              where even.facility_id==faciltyid

                                              select even. parent_person_id ).Distinct();

            return sch_view_class_student_list.ToList();
