asp.net中給Gridview控件增加自動序列模板列代碼

             <asp:TemplateField HeaderText="排序">
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text="<%# gridview1.pageindex * gridview1.pagesize + gridview1.rows.count + 1 %>"></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
