如何得到DataGridView某个单元格/行/列的坐标？(类似控件的left,top属性)

Question

我试了下用这样的方法
    dg.Rows.Add(9);
    Rectangle rec = dg.GetRowDisplayRectangle(8, false);
得到的rec是这样：
{X = 0 Y = 0 Width = 0 Height = 0} System.Drawing.Rectangle还有没有其它方法呢？

int rowIndex = 1;
                int columnIndex = 1;
                int X = 0, Y = 0;                if (dataGridView.RowHeadersVisible) X += dataGridView.RowHeadersWidth;
                for (int i = dataGridView.FirstDisplayedScrollingColumnIndex; i < ColumnIndex; i++)
                {
                    if (dataGridView.Columns[i].Visible) X += dataGridView.Columns[i].Width + dataGridView.Columns[i].DividerWidth;
                }
                X -= dataGridView.FirstDisplayedScrollingColumnHiddenWidth;                if (dataGridView.ColumnHeadersVisible) Y += dataGridView.ColumnHeadersHeight;
                for (int i = dataGridView.FirstDisplayedScrollingRowIndex; i < RowIndex; i++)
                {
                    if (dataGridView.Rows[i].Visible) Y += dataGridView.Rows[i].Height + dataGridView.Rows[i].DividerHeight;
                }
