GridView添加序号列

在GridView控件第0列添加序号列：

<asp:BoundField HeaderText="序号" >
    <ItemStyle HorizontalAlign="Center" />
    <HeaderStyle HorizontalAlign="Center" Width="30px" />
</asp:BoundField>

protected void gridViewCPImportPercent_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Cells[0].Text = (e.Row.RowIndex + 1).ToString();

        ////如果使用了分页控件且希望序号在翻页后不重新计算，使用下面方法
        //int indexID = (AspNetPager1.CurrentPageIndex - 1) * AspNetPager1.PageSize + e.Row.RowIndex + 1;
        //e.Row.Cells[0].Text = indexID.ToString();
    }
}
