gridview分页跳转问题

Question

现有代码：
        <PagerTemplate>
                当前第:
                <asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
                页/共:
                <asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
                页
                <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
                    Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首页</asp:LinkButton>
                <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
                    CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一页</asp:LinkButton>
                <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
                    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一页</asp:LinkButton>
                <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
                    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾页</asp:LinkButton>
                转到第
                <asp:TextBox ID="txtNewPageIndex" runat="server" Width="30px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页
                <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
                    CommandName="go" Text="GO" />
            </PagerTemplate>
 
后台代码：
        protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            BTchaxun_Click(null, null);
            // 得到该控件
            GridView theGrid = sender as GridView;
            int newPageIndex = 0;
            if (e.NewPageIndex == -2)
            {
                //点击了Go按钮
                TextBox txtNewPageIndex = null;
                GridViewRow pagerRow = theGrid.BottomPagerRow;                if (pagerRow != null)
                {
                    //得到text控件
                    txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
                }
                if (txtNewPageIndex != null)
                {
                    //得到索引
                    newPageIndex = Convert.ToInt32(txtNewPageIndex.Text) - 1;
                }
            }
            else
            {
                //点击了其他的按钮
                newPageIndex = e.NewPageIndex;
            }
            //防止新索引溢出
            newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
            newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;            //得到新的值
            theGrid.PageIndex = newPageIndex;            //重新绑定
            GridView1.DataBind();
        }问题是：点了前页后页首末页都可以，但就只有那个转到多少页没用，每次都转到第一页，我调试了貌似就没有执行if (e.NewPageIndex == -2)
            {
                //点击了Go按钮
                TextBox txtNewPageIndex = null;
                GridViewRow pagerRow = theGrid.BottomPagerRow;                if (pagerRow != null)
                {
                    //得到text控件
                    txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
                }
                if (txtNewPageIndex != null)
                {
                    //得到索引
                    newPageIndex = Convert.ToInt32(txtNewPageIndex.Text) - 1;
                }
            }
这句里边的代码，请高手看看哪里错了

Answer 1

加一句，貌似点了转页后连PageIndexChanging都没执行。

Answer 2

有木有高手啊，我改了下把if (e.NewPageIndex == -2)改为-3就会响应了，但是又有个问题了，就是如果我现在在第三页，我想跳到第五页，于是我把textbox里改为5然后按go按钮，但是newPageIndex = Convert.ToInt32(txtNewPageIndex.Text) - 1得到的却不是5还是刚才的3，我就郁闷了，搞很久了，求高手啊

Answer 3

把分页程序代码分成一个过程，然后调用。  if (!IsPostBack)关注一下看是套在里边，还是套在它外边。
