gridview更新和取消事件不执行，下去吃饭的时候还没事呢

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            databind();
        }
    }    public void databind()//绑定GridView
    {
        DataTable dt = new DataTable();
        string sql = "select * from x_link";
        dt = sqlhelper.GetTable(sql);
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
    protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)//GridView编辑事件
    {
        GridView1.EditIndex = e.NewEditIndex;
        databind();
    }
    protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)//GridView取消编辑事件
    {
        GridView1.EditIndex = -1;
        databind();
    }
    protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)//GridView更新事件
    {
        int id = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value.ToString());
        string name = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[0].Controls[0])).Text.ToString();
        string url = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString();
        string sql = "update x_link set x_lname=@name,x_lurl=@url where id=" + id;

有用到母版面?你查看HTML源代码,看是否参找到两个以上的form,而且两个是嵌套在一起的
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="link.ascx.cs" Inherits="control_link" %>
<asp:GridView ID="GridView1" runat="server" DataKeyNames="id"
    AutoGenerateColumns="False" onrowcancelingedit="GridView1_RowCancelingEdit"
    onrowediting="GridView1_RowEditing" onrowupdating="GridView1_RowUpdating"
    BorderWidth="0px" CellSpacing="20" GridLines="None">
    <RowStyle Font-Size="15px" Height="50px" HorizontalAlign="Center" Width="200px"
        VerticalAlign="Middle" />
    <Columns>
        <asp:BoundField DataField="x_lname" HeaderText="网站名称" />
        <asp:BoundField DataField="x_lurl" HeaderText="网站网址" />
        <asp:CommandField ShowEditButton="True" />
    </Columns></asp:GridView>
下面是引用用户控件的主页面的源代码

article.aspx里面有个<asp:PlaceHolder runat="server" ID="ContentHolder"></asp:PlaceHolder>这个家伙加载link.ascx，就是gridview的那个用户控件上面有源代码
假设你们有源代码管理系统的支持的话，看看当前的版本是否提交，然后——删除代码吧！bug的位置可以通过正快地删除代码，自己更快地定位的。实际上我使用测试驱动方式，如果亦步亦趋、一边测试一遍遍写代码，你的这种情况是不会出现的。因为有什么细微的bug，其它测试程序立刻就将bug定位出来了。不用等到整个程序不行了，才发现问题。
XViewStateFilesPage
是把viewstate写在服务器端的类，你们看见了吧 article.aspx里面调用了4个用户控件，其中就包括link.ascx，但是其他三个控件都起作用了，不论自动回发，删除，添加，都执行了，就到这个gridview的用户控件link.ascx就不起作用了，纠结啊
form 是在母版页里面

   试试看
对于这个问题已经有答案了，是我再服务器段保存viewstate的事情不在服务器端保存viewstate的话，是不会出错的，aritcle.apsx采用母版页，然后后台动态加载4个控件，经测试，来回切换的话，会出现与上一控件树师徒不一样的情况，并且 gridview编辑事件起作用，更新取消事件不起作用，目前我对viewsate懂得不是很多，希望以后能把这个问题解决了，这个页面是后台页面，viewstate不是很大，暂且保留，期待以后解决
