GridView 自动增加序号

第一种方式,直接在Aspx页面GridView模板列中.这种的缺点是到第二页分页时又重新开始了. 
<asp:TemplateField HeaderText="序号" InsertVisible="False">                       
    <ItemTemplate>               
        <%#Container.DataItemIndex+1%>            
    </ItemTemplate>             
</asp:TemplateField>

第二种方式分页时进行了计算,这样会累计向下加. 

<asp:TemplateField HeaderText="序号" InsertVisible="False">

           <ItemStyle Horiznotallow="Center" />

           <HeaderStyle Horiznotallow="Center"/>

            <ItemTemplate>

                   <asp:Label ID="Label2" runat="server" Text='<%# this.GridView1.PageIndex * this.GridView1.PageSize + this.GridView1.Rows.Count + 1%>' />

           </ItemTemplate>

</asp:TemplateField>

 

还有一种方式放在cs代码中,和第二种相似.

<asp:BoundField HeaderText="序号" ></asp:BoundField> 
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)         
{             
    if (e.Row.RowIndex != -1)             
    {                 
        int indexID = this.GridView1.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1;                 
        e.Row.Cells[0].Text = indexID.ToString();             
    }         
}
