为了表示行号,我们可以在DataGridView的RowPostPaint事件中进行绘制。RowPostPaint事件,具体可以参照MSDN。

下面是实现代码:

        private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)

        {
            System.Drawing.Rectangle rectangle = 
                new System.Drawing.Rectangle(e.RowBounds.Location.X,e.RowBounds.Location.Y,
                    dataGridView1.RowHeadersWidth - 4,e.RowBounds.Height);
               
            TextRenderer.DrawText(e.Graphics, (e.RowIndex + 1).ToString(),
                dataGridView1.RowHeadersDefaultCellStyle.Font,rectangle,
                dataGridView1.RowHeadersDefaultCellStyle.ForeColor, TextFormatFlags.VerticalCenter | TextFormatFlags.Right);

        }
