让DataGridView显示行号

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);

}
