Winform 中DataGridView控件添加行标题

1         /// <summary>
2         /// 行状态更改时发生
3         /// </summary>
4         /// <param name="sender"></param>
5         /// <param name="e"></param>
6         private void dataGridView1_RowStateChanged(object sender, DataGridViewRowStateChangedEventArgs e)
7         {             
8　　　　//e.Row.HeaderCell.Value =  string.Format("{0}", e.Row.Index + 1);
9             e.Row.HeaderCell.Value = (e.Row.Index + 1).ToString();//添加行号
10        }

 1         /// <summary>
 2         /// 所有单元格绘制后，执行 行绘制时发生
 3         /// </summary>
 4         /// <param name="sender"></param>
 5         /// <param name="e"></param>
 6         private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
 7         {
 8             //
 9             System.Drawing.Rectangle rectangle = new Rectangle(e.RowBounds.Location.X, e.RowBounds.Y, this.dataGridView1.RowHeadersWidth - 4, this.dataGridView1.ColumnHeadersHeight);
10             TextRenderer.DrawText(e.Graphics, (e.RowIndex + 1).ToString(), this.dataGridView1.RowHeadersDefaultCellStyle.Font, rectangle, this.dataGridView1.RowHeadersDefaultCellStyle.ForeColor, TextFormatFlags.VerticalCenter | TextFormatFlags.Right);//”TextFormatFlags.VerticalCenter | TextFormatFlags.Right“中“|”有增加的作用，此处添加了两种文本字符格式样式
