datagridview最前面的列自動顯示數字
        private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
            using (SolidBrush b = new SolidBrush(this.dataGridView1.RowHeadersDefaultCellStyle.ForeColor))
            {
                e.Graphics.DrawString(Convert.ToString(e.RowIndex + 1, System.Globalization.CultureInfo.CurrentUICulture), e.InheritedRowStyle.Font, b, e.RowBounds.Location.X + 15, e.RowBounds.Location.Y + 5);
            }
        }

datagridview在最前面的列顯示“序號”
        private void dataGridView1_Paint(object sender, PaintEventArgs e)
        {
            using (SolidBrush b = new SolidBrush(this.dataGridView1.RowHeadersDefaultCellStyle.ForeColor))
            {
                e.Graphics.DrawString("序號", dataGridView1.Font, b, 8, 5);
            }
        }

將焦點設置到某一個Cell上
this.dataGridView1.CurrentCell = dataGridView[0,1];

DataGridView綁定數組問題
   用数组作为DataGridView数据源的时候,它只显示数组里每项的长度.
因為datasource綁的是對象屬性，所以建一個包含字符串的類,然後用對象數組是可以達到目的
public class TestView
{
private String m_Test;
public String Test
{
get { return m_Test; }
set { m_Test = value; }
}
}

　　在VS2005的C＃ WinForm编程中，有一个DataGridView控件，要在其上按右键弹出右键菜单前选中当前行，可以在CellMouseDown事件中加入如下代码：

1        private void DataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
2        {
3             DataGridView1.ClearSelection();
4             DataGridView1.Rows[e.RowIndex].Selected = true;
5             DataGridView1.CurrentCell = DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
6         }
