GridView添加自动编号列

在开发中使用的GridView显示数据，并且需要它记录集的行编号，这样就可以很清楚的知道有多少条数据。

通过查看资料，自己做了个GridView模板，并带有分页功能示例：

<asp:GridView ID="GView_Data" runat="server" AllowPaging="True" Height="1px" Font-Size="10pt" BackColor="White" BorderColor="#E7E7FF" BorderWidth="1px" OnRowDataBound="GView_Data_RowDataBound" >  
                <Columns>
                    <asp:TemplateField HeaderText="序号" InsertVisible="False" ControlStyle-Width="20px" >
                         <headerstyle width="5%" horizontalalign="Center" />
                         <ItemTemplate>
                            <asp:Label id="Label2" runat="server" Width="100%" Text="<%# this.GView_Data.PageIndex * this.GView_Data.PageSize  + this.GView_Data.Rows.Count + 1 %>" ForeColor="Blue"></asp:Label> 
                         </ItemTemplate>
                    </asp:TemplateField>
                </Columns>
                <PagerTemplate>
                    <table width="100%">
                        <tr>
                            <td style="text-align: left">
                                第<asp:Label ID="lblPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1  %>'></asp:Label>页
                                共/<asp:Label ID="lblPageCount" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount  %>'></asp:Label>页
                                <asp:LinkButton ID="btnFirst" runat="server" CausesValidation="False" CommandArgument="First"
                                    CommandName="Page" Text="首页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
                                <asp:LinkButton ID="btnPrev" runat="server" CausesValidation="False" CommandArgument="Prev"
                                    CommandName="Page" Text="上一页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
                                <asp:LinkButton ID="btnNext" runat="server" CausesValidation="False" CommandArgument="Next"
                                    CommandName="Page" Text="下一页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
                                <asp:LinkButton ID="btnLast" runat="server" CausesValidation="False" CommandArgument="Last"
                                    CommandName="Page" Text="尾页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
                                <asp:TextBox ID="txtNewPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1  %>'
                                    Width="20px"></asp:TextBox>
                                <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="Go"
                                    CommandName="Page" Text="GO" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton><!-- here set the CommandArgument of the Go Button to '-1' as the flag -->
                            </td>
                        </tr>
                    </table>
                    </PagerTemplate>
                    <FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
                    <RowStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />
                    <PagerStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" HorizontalAlign="Right" />
                    <SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />
                    <HeaderStyle BackColor="#7481BA" Font-Bold="True" ForeColor="Yellow" HorizontalAlign="Left" Wrap="False" />
                    <AlternatingRowStyle BackColor="#F7F7F7" />
</asp:GridView>

分页功能实现方法省略。
