從不在GridView中的組合框在devexpressfocusedrowhandle中設置單元格值

Question

我想在按下按鈕時在TECNICO列中設置組合框文本。

但是在運行時，我無法在TECNICO列中顯示設置值

private void asing_Click(object sender, EventArgs e)
        {
            if ( tecnicos.Text.Length > 0)
            {
                try
                {
                    SqlConnection con = conec.ObtenerCon();
                    SqlCommand sel = new SqlCommand("SELECT * FROM RTID_STATUS WHERE ID_RTID='" + gridView1.GetFocusedRowCellValue(colID_RTID) + "'", con);
                    SqlDataReader rs = sel.ExecuteReader();
                        if (rs.Read())
                        {
                            con.Close();
                            SqlConnection con1 = conec.ObtenerCon();
                            MessageBox.Show(" hay :\t" + gridView1.GetFocusedRowCellValue(colID_RTID));
                            SqlCommand up = new SqlCommand("UPDATE RTID_STATUS SET ID_TECH='" + idtec(tecnicos.Text) + "'", con1);
                            gridView1.SetRowCellValue(gridView1.FocusedRowHandle, tec,tecnicos.Text.ToString());
                            gridView1.RefreshRow(gridView1.FocusedRowHandle);
                            SqlDataReader resu = up.ExecuteReader();
                            con1.Close();
                        }
                        else

該值是否存在於RepositoryItemComboBoxEdit的Items集合中？
