gridview增加自动序号列

1. 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.
3.             <asp:TemplateField HeaderText="序号" InsertVisible="False">
4.               <ItemStyle HorizontalAlign="Center" />
5.               <HeaderStyle HorizontalAlign="Center" Width="5%" />
6.              <ItemTemplate>
7.               <%#Container.DataItemIndex+1%>
8.             </ItemTemplate>
9.             </asp:TemplateField>
12. 第二种方式分页时进行了计算,这样会累计向下加.
14.             <asp:TemplateField HeaderText="序号" InsertVisible="False">
15.               <ItemStyle HorizontalAlign="Center" />
16.               <HeaderStyle HorizontalAlign="Center" Width="5%" />
17.              <ItemTemplate>
18.                  <asp:Label ID="Label2" runat="server" Text='<%# this.MyListGridView.PageIndex * this.MyListGridView.PageSize + this.MyListGridView.Rows.Count + 1%>'/>
19.             </ItemTemplate>
20.             </asp:TemplateField>
24. 还有一种方式放在cs代码中,和第二种相似.
26.     <asp:BoundField HeaderText="序号" >
27.               <ItemStyle HorizontalAlign="Center" />
28.               <HeaderStyle HorizontalAlign="Center" Width="5%" />
29.           </asp:BoundField>
32.         protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)
33.         {
34.             if (e.Row.RowIndex != -1)
35.             {
36.                 int indexID = this.myGridView.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1;
37.                  e.Row.Cells[0].Text = indexID.ToString();
38.              }
39.          }
