I add each Item (record) into Lookupedit but an error

                // Open connection database
                Cnn.ConnectSQL();   
               SqlDataAdapter da = new SqlDataAdapter("SELECT TabSTAFF.IDSTAFF, TabSTAFF.NAMESTAFF FROM TabSTAFF ORDER BY TabSTAFF.IDSTAFF;", Cnn.objConnect);
                DataSet ds = new DataSet();    
                DataTable dt = new DataTable();
                da.Fill(ds, "TabSTAFF");                         
                dt = ds.Tables["TabSTAFF"];
 
                kpNhanvien.EditValue = dt.Rows[0]["NAMESTAFF"].ToString();
                foreach (DataRow dr in dt.Rows)
                {
                      / / Get an error immediately below this line
                      lkpNhanvien.Properties.Columns.Add(new LookUpColumnInfo(dr["IDSTAFF"].ToString(), dr["NAMESTAFF"].ToString()));                    
 
                }
                //lkpQuyensd.Properties.DataSource = dt;
                lkpNhanvien.Properties.DisplayMember = "NameStaff";
                lkpNhanvien.Properties.ValueMember = "IDstaff";
 

And I want to remove each item in Lookupedit ? how to write code looupedit ?
