        问题：
        如何将list<T> GetXinXiList(int departmentID) 的返回值 绑定到treeview和分页DataGrid？
        
        public StuResult Result { get; set; }
        private Department studentDao = new Department();
        public void Query(int size, int pageIndex)
        {
            Result.Total = studentDao.TotalCount;
            Result.Students = studentDao.XinXiLists.Skip((pageIndex - 1) * size).Take(size).ToList();        }

        private void PagingDataGrid_PagingChanged(object sender, CustomControlLibrary.PagingChangedEventArgs args)
        {
            Query(args.PageSize, args.PageIndex);
        }
    }
}
