求救DataGrid翻转跳转功能的实现

Question

前台是这样的： <asp:TextBox runat="server" ID="tbhao" Width="20px"> </asp:TextBox>&nbsp; <asp:HyperLink runat="server" ID="indicate" CssClass="daohang">跳转到该页 </asp:HyperLink> 
后台： int CurPage; 
        if (Request.QueryString["Page"] != null) 
            CurPage = Convert.ToInt32(Request.QueryString["Page"]); 
        else 
          
          CurPage = 1; 
indicate.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage); ; 
        if (!ps.IsFirstPage) 
            prepage.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1); 
        if (!ps.IsLastPage) 
            nextpage.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1); 
怎么在前面用IF语句给CurPage赋值是tbhao.text。谢谢。
