关于GridView分页跳转的问题
GridView分页跳转到几页的功能不能实现。下面代码中txtNewPageIndex的值取得不对。

ASPX 代码:
HTML code
            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnPageIndexChanging="GridView1_PageIndexChanging"                OnPageIndexChanged="GridView1_PageIndexChanged" AllowPaging="true" PageSize="20"                Height="117px" Width="800">                <FooterStyle BackColor="#FFFFFF" Font-Bold="True" ForeColor="White" />                <Columns>                    <asp:TemplateField HeaderText="ID" ItemStyle-Width="50px">                        <ItemTemplate>                            <asp:Label ID="Labelid" runat="server" Text='<%# Bind("id") %>'></asp:Label>                        </ItemTemplate>                    </asp:TemplateField>                    <asp:TemplateField HeaderText="IP" ItemStyle-Width="250px">                        <ItemTemplate>                            <asp:Label ID="Labelip" runat="server" Text='<%# Eval("ip")+" / "+IPtoText(Eval("ip").ToString()) %>'></asp:Label>                        </ItemTemplate>                    </asp:TemplateField>                    <asp:TemplateField HeaderText="类型" ItemStyle-Width="220px">                        <ItemTemplate>                            <asp:Label ID="Labeltypeid" runat="server" Text='<%# typeidtotext(Eval("typeid").ToString()) %>'></asp:Label>                        </ItemTemplate>                    </asp:TemplateField>                    <asp:TemplateField HeaderText="操作" ItemStyle-Width="100px">                        <ItemTemplate>                            <!--<a style="color: #000;" href="javascript:Update(<%# Eval("id") %>)">修改</a>-->                            <a style="color: #000;" href="EditLink.aspx?id=(<%# Eval("id") %>)">修改</a> <span                                onclick="return window.confirm('你真要删除所选项?')"><a href="dellink.aspx?id=<%# Eval("id") %>"                                    style="color: Black;">删除</a></span>                        </ItemTemplate>                    </asp:TemplateField>                </Columns>                <RowStyle BackColor="#eef2ff" ForeColor="#333333" />                <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" />                <PagerStyle BackColor="#7D9AFF" ForeColor="#333333" HorizontalAlign="Center" />                <HeaderStyle BackColor="#7D9AFF" Font-Bold="True" ForeColor="White" Height="30" />                <AlternatingRowStyle BackColor="White" />                <PagerTemplate>                    第<asp:Label ID="lblPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页                    共/<asp:Label ID="lblPageCount" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount %>' />页                    <asp:LinkButton ID="lbnFirst" runat="Server" Text="首页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'                        CommandName="Page" CommandArgument="First"></asp:LinkButton>                    <asp:LinkButton ID="lbnPrev" runat="server" Text="上一页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'                        CommandName="Page" CommandArgument="Prev"></asp:LinkButton>                    <asp:LinkButton ID="lbnNext" runat="Server" Text="下一页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != (((GridView)Container.NamingContainer).PageCount - 1) %>'                        CommandName="Page" CommandArgument="Next"></asp:LinkButton>                    <asp:LinkButton ID="lbnLast" runat="Server" Text="尾页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != (((GridView)Container.NamingContainer).PageCount - 1) %>'                        CommandName="Page" CommandArgument="Last"></asp:LinkButton>                    跳到<asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />                    <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-1" CommandName="Page" Text="GO" OnClick="Turn_Click" />                        <asp:RegularExpressionValidator                            ID="RegularExpressionValidatorSum" runat="server" ControlToValidate="txtNewPageIndex"                            Display="Dynamic" ErrorMessage="RegularExpressionValidator" ValidationExpression="^[-]?(\d+\.?\d*|\.\d+)$">(必须为数字)</asp:RegularExpressionValidator>                    <!-- here set the CommandArgument of the Go Button to '-1' as the flag -->                </PagerTemplate>            </asp:GridView>
