vb.net datagridview 几行一起排序

黑体字下面是要这样吗？ vb的代码 我不太懂，只会c#的，  但是给你个思路， 就是纵向合并单元格嘛。 

我贴一段c#的代码，。， 您理解下， 应该不困难。。。

代码 把AllowUserToAddRows设置为false

      private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
        {
            //纵向合并
            if (this.dataGridView1.Columns["Name"].Index == e.ColumnIndex && e.RowIndex >= 0)
            {

                using (
                    Brush gridBrush = new SolidBrush(this.dataGridView1.GridColor),
                    backColorBrush = new SolidBrush(e.CellStyle.BackColor))
                {
                    using (Pen gridLinePen = new Pen(gridBrush))
                    {
                        // 擦除原单元格背景
                        e.Graphics.FillRectangle(backColorBrush, e.CellBounds);
                        /**/
                        ////绘制线条,这些线条是单元格相互间隔的区分线条,
                        ////因为我们只对列name做处理,所以datagridview自己会处理左侧和上边缘的线条
                        if (e.RowIndex != this.dataGridView1.RowCount - 1)
                        {
                            try
                            {
                               
if (e.Value.ToString() != this.dataGridView1.Rows[e.RowIndex +
1].Cells[e.ColumnIndex].Value.ToString())
                                {

                                    e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom - 1,
                                    e.CellBounds.Right - 1, e.CellBounds.Bottom - 1);//下边缘的线
                                    //绘制值
                                    if (e.Value != null)
                                    {
                                        e.Graphics.DrawString((String)e.Value, e.CellStyle.Font,
                                            Brushes.Crimson, e.CellBounds.X + 2,
                                            e.CellBounds.Y + 2, StringFormat.GenericDefault);
                                    }
                                }
                            }
                            catch (Exception ex)
                            {
                               
                            }
                        }
                        else
                        {
                            e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom - 1,
                                e.CellBounds.Right - 1, e.CellBounds.Bottom - 1);//下边缘的线
                            //绘制值
                            if (e.Value != null)
                            {
                                e.Graphics.DrawString((String)e.Value, e.CellStyle.Font,
                                    Brushes.Crimson, e.CellBounds.X + 2,
                                    e.CellBounds.Y + 2, StringFormat.GenericDefault);
                            }
                        }
                        //右侧的线
                        e.Graphics.DrawLine(gridLinePen, e.CellBounds.Right - 1,
                            e.CellBounds.Top, e.CellBounds.Right - 1,
                            e.CellBounds.Bottom - 1);

                        e.Handled = true;
                    }
                }
            }

        }

下面是我用的datatable   这个dataset是网上copy的

  DataSet dataset = new DataSet();//库
            //表
            DataTable myfriends = new DataTable("myfriends");
            //列
            DataColumn dcName = new DataColumn();
            dcName.ColumnName = "Name";
            dcName.DataType = typeof(string);
            dcName.MaxLength = 8;
            DataColumn dcPhone = new DataColumn();
            dcPhone.ColumnName = "telephone";
            dcPhone.DataType = typeof(string);
            dcPhone.MaxLength = 11;
            //添加列
            myfriends.Columns.Add(dcName);
            myfriends.Columns.Add(dcPhone);
            //添加1行
            DataRow row = myfriends.NewRow();//得到空行
            row["Name"] = "小明";
            row["telephone"] = "13888888888";
            DataRow row1 = myfriends.NewRow();//得到空行
            row1["Name"] = "小明";
            row1["telephone"] = "15859859888";
            DataRow row2 = myfriends.NewRow();//得到空行
            row2["Name"] = "猪猪";
            row2["telephone"] = "15999999999";
            myfriends.Rows.Add(row);
            myfriends.Rows.Add(row1);
            myfriends.Rows.Add(row2);
            //添加表到dataset
            dataset.Tables.Add(myfriends);
            dataGridView1.DataSource = myfriends;
