winform DataGridView 合并单元格

[weimei521]

根据其中的组合名称和cl和cf_flag，如果相同，就实现下面的效果

 for (int i = 0; i < dt.Rows.Count; i++)
                {
                    dt.Rows[i]["emergy_type"] = hc.getEncoding(dt.Rows[i]["emergy_type"].ToString().Trim(), 0);
                    dt.Rows[i]["name"] = hc.getEncoding(dt.Rows[i]["name"].ToString().Trim(), 0);
                    dt.Rows[i]["drugname"] = hc.getEncoding(dt.Rows[i]["drugname"].ToString().Trim(), 0);
                    dt.Rows[i]["specification"] = hc.getEncoding(dt.Rows[i]["specification"].ToString().Trim(), 0);
                    dt.Rows[i]["unit"] = hc.getEncoding(dt.Rows[i]["unit"].ToString().Trim(), 0);
                    dt.Rows[i]["flag"] = hc.getEncoding(dt.Rows[i]["flag"].ToString().Trim(), 0);
                    dt.Rows[i]["check_equip"] = hc.getEncoding(dt.Rows[i]["check_equip"].ToString().Trim(), 0);
                    dt.Rows[i]["old_ill"] = hc.getEncoding(dt.Rows[i]["old_ill"].ToString().Trim(), 0);
                    dt.Rows[i]["adresult"] = hc.getEncoding(dt.Rows[i]["adresult"].ToString().Trim(), 0);
                    dt.Rows[i]["information"] = hc.getEncoding(dt.Rows[i]["information"].ToString().Trim(), 0);
                    dt.Rows[i]["goal"] = hc.getEncoding(dt.Rows[i]["goal"].ToString().Trim(), 0);
                    dt.Rows[i]["group_name"] = hc.getEncoding(dt.Rows[i]["group_name"].ToString().Trim(), 0);
                    dt.Rows[i]["deptname"] = hc.getEncoding(dt.Rows[i]["deptname"].ToString().Trim(), 0);
                    dt.Rows[i]["execName"] = hc.getEncoding(dt.Rows[i]["execName"].ToString().Trim(), 0);
                    dt.Rows[i]["parent_name"] = hc.getEncoding(dt.Rows[i]["parent_name"].ToString().Trim(), 0);
                    dt.Rows[i]["cf_flag"] = hc.getEncoding(dt.Rows[i]["cf_flag"].ToString().Trim(), 0);
                    if (dt.Rows[i]["payname"].ToString() == "0")
                    {
                        dt.Rows[i]["payname"] = "已收费";
                    }
                    if (dt.Rows[i]["payname"].ToString() == "5")
                    {
                        dt.Rows[i]["payname"] = "未收费";
                    }
                }

这是加载的循环语句，该怎么实现

            this.dgv.CellPainting += (sc, ec) =>
            {
                ec.AdvancedBorderStyle.Bottom = DataGridViewAdvancedCellBorderStyle.None;
                if (ec.RowIndex < 1 || ec.ColumnIndex < 0)
                    return;

                if (IsCellValueSame((DataGridView)sc, ec.ColumnIndex, ec.RowIndex))
                    ec.AdvancedBorderStyle.Top = DataGridViewAdvancedCellBorderStyle.None;
                else
                    ec.AdvancedBorderStyle.Top = ((DataGridView)sc).AdvancedCellBorderStyle.Top;
            };

IsCellValueSame:

 /// <summary>
        /// 验证是否相等
        /// </summary>
        /// <param name="dgv">dataGridView对象</param>
        /// <param name="columnIndex">列索引</param>
        /// <param name="rowIndex">行索引</param>
        private bool IsCellValueSame(DataGridView dgv, int columnIndex, int rowIndex)
        {
            DataGridViewCell cellPrev = dgv[columnIndex, rowIndex];
            DataGridViewCell cellNext = dgv[columnIndex, rowIndex - 1];
            // 判断值
            if (cellPrev.Value == null || cellNext.Value == null)
                return false;

            return cellPrev.Value.ToString() == cellNext.Value.ToString();
        }

[quote=引用 1 楼 duanzi_peng 的回复:] 没太明白，这里怎么判断的组合名称和cf_flag
