datagridview 左边设置一列 数字从小到大往下排列

Question

请问，有没有可能做到Datagridview绑定数据的同时，我在左边也动态的生成相应的行数，且这列可被我赋值
我是想做一个排名的程序，右边根据排序已经做出来，可是左边加不进去数字
谢谢

private void DataGridView1_CellPainting(object sender,DataGridViewCellPaintingEventArgs e)
{
    if (e.ColumnIndex < 0 && e.RowIndex >= 0)
    {        e.Paint(e.ClipBounds, DataGridViewPaintParts.All);
        Rectangle indexRect = e.CellBounds;
       indexRect.Inflate(-2, -2);
        TextRenderer.DrawText(e.Graphics,(e.RowIndex + 1).ToString(),e.CellStyle.Font,indexRect,e.CellStyle.ForeColor,TextFormatFlags.Right | TextFormatFlags.VerticalCenter);
        e.Handled = true;
    }
}

在DataGridView的RowPostPaint事件中添加以下代码： 
DataGridView DGV = sender as DataGridView; 
Rectangle rec = new Rectangle(e.RowBounds.Location.X, 
                              e.RowBounds.Location.Y, 
                              DGV.RowHeadersWidth - 4, 
                              e.RowBounds.Height); 
TextRender.DrawText(e.Graphics, 
                  (e.RowIndex+1).ToString(), 
                    DGV.RowHeadersDefaultCellStyle.Font, 
                    rec, 
                    DGV.RowHeadersDefaultCellStyle.ForeColor, 
                    TextFormatFlags.VerticalCenter|TextFormatFlags.Right); 

Answer 4

  <asp:TemplateField HeaderText="编号"> 
                    <ItemStyle Width="5%" HorizontalAlign="Center" />
                    <ItemTemplate > 
                    <%# this.GridView1.PageIndex  * this.GridView1.PageSize + Container.DataItemIndex + 1%> 
                    </ItemTemplate> 
                    </asp:TemplateField>

Answer 5

我们面的代码是经过测试的：        private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
        {
            DataGridViewRow row;
            for (int i = 0; i < dataGridView1.Rows.Count; i++)
            {
                row = dataGridView1.Rows[i];
                row.HeaderCell.Value = (i + 1).ToString();
            }
        }
