在GridView控件第0列添加序号列：




[html] view plain copy
<asp:BoundField HeaderText="序号" >  
    <ItemStyle HorizontalAlign="Center" />  
    <HeaderStyle HorizontalAlign="Center" Width="30px" />  
</asp:BoundField>  




为GridView添加OnRowDataBound事件，事件名称为gridViewCPImportPercent_RowDataBound，代码如下：
[csharp] view plain copy
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();  
    }  
}
