Gridview 的刷新问题~~菜鸟问题

我在一个页中，gridview和detailsview各分别绑定一个数据源，但在数据库中指向同一个表，当gridview中选中某项之后，用Response.Redirect跳到同一个页面，同时用？向detailsview传值，想在detailsview中更新数据库后，gridview中同步显示更新，但是用Response.AddHeader("Refresh", "0");或者 Response.Redirect("该页面.aspx");都只是页面更新，但gridview并不更新，有没有什么解决方法？麻烦说的详细些。代码如下：
<%@ Page Language="C#" MasterPageFile="~/Administrator/AdmiMasterPage.master" AutoEventWireup="true" CodeFile="Tip.aspx.cs" Inherits="Administrator_Tip" Title="Untitled Page" %><asp:Content ID="Content1" ContentPlaceHolderID="MailContentPlaceHolder" Runat="Server">

  1.   

    看着头晕啊。
    想刷新gridview 最简单的方法就是再绑定一次。
    把绑定单拿出来写个绑定方法。调用绑定方法。
      

  2.   

    asp。net的话用reapter比gridview好控制。
      

  3.   

    绑定gridview的数据有没有判断回发
    if(!IsPostBack){
      绑定数据
    }
    或者放到
    protected void Page_PreRender(object sender,Eventages e){
     这里绑定也一样就不用判断回发了
    }
      

  4.   

    没有错啊，只是同一个页面中既有gridview又有detailsview，指向同一个表，想通过detailsview改变数据库时，让gridview同步更新
      

  5.   

    是想在网页下，让gridview与数据库同步更新，不是后台写啊，怎么重绑定…………
