 代码如下：

 

 

 1  private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
 2         {
 3             var dgv = (DataGridView)sender;
 4             if (dgv.RowHeadersVisible)
 5             {
 6                 Rectangle rect = new Rectangle(e.RowBounds.Left, e.RowBounds.Top,
 7                                                dgv.RowHeadersWidth, e.RowBounds.Height);
 8                 rect.Inflate(-2, -2);
 9                 TextRenderer.DrawText(e.Graphics,
10                     (e.RowIndex + 1).ToString(),
11                     e.InheritedRowStyle.Font,
12                     rect, e.InheritedRowStyle.ForeColor,
13                     TextFormatFlags.Right | TextFormatFlags.VerticalCenter
14                     );
15 
16             }
17         }
