我需要使用更新面板中的按钮重定向页面。但是当我试着这样做的时候，它对我不起作用。有人能帮我吗。请在下面找到我的代码

   <body>
     <form id="form1" runat="server">
          <asp:ScriptManager ID="ScriptManager1" runat="server" />
        <div>
            <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
                <ContentTemplate>
            <asp:Label ID="Label2" runat="server" Text="Label" Width="345px"></asp:Label><br />
                    <br />    
                    <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder> 
                    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>     
                    <asp:Label ID="Label3" runat="server" Text="Label"></asp:Label>        
                </ContentTemplate>
                <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Button2" EventName="Click" />
                 <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />

                </Triggers>
            </asp:UpdatePanel>
              <asp:Timer ID="Timer1" runat="server" ontick="Timer1_Tick" Interval="500">
                    </asp:Timer>
            <br />
            <asp:Button ID="Button1" runat="server" Text="Button" Width="344px" OnClick="Button1_Click" /><br />
            <asp:Button ID="Button2" runat="server" Text="Button" />
            <br />
            <br />
            &nbsp;</div>
    </form>
              </body>

我会这样做：

将按钮放入updatePanel并禁用它

将其作为触发器放在标签内

当勾号事件发生时，启用按钮

这里的问题是，ImageButton仅在计时器计时后添加到页面。如果希望为此类动态添加的控件调用服务器端处理程序，则必须在每次回发时向页面添加。以下是如何使用键视图状态完成此操作：

protected void Page_Load(object sender, EventArgs ea)
{
    bool? addHotelResultButton = ViewState["AddHotelResultButton"] as bool?;
    if (addHotelResultButton.HasValue && addHotelResultButton.Value)
    {
        AddHotelResultButton();
    }
}

protected void Timer1_Tick(object sender, EventArgs e)
{
    ViewState["AddHotelResultButton"] = true;
    AddHotelResultButton();
}

protected void AddHotelResultButton()
{
    Timer1.Enabled = false;
    Label1.Text = DateTime.Now.ToString();
    Label2.Text = DateTime.Now.ToString();
    Label3.Text = DateTime.Now.ToString();
    ImageButton testbtn = new ImageButton();
    testbtn.ID = "testbtnid";
    testbtn.Click += new System.Web.UI.ImageClickEventHandler(this.imgBtn_Click);
    testbtn.ImageUrl = "images/heroAccent.png";
    PlaceHolder1.Controls.Add(testbtn);
}

要重新加载整页还是要在更新面板中加载新页？要重新加载整页为什么要在计时器启动时禁用计时器？

protected void Page_Load(object sender, EventArgs ea)
{
    bool? addHotelResultButton = ViewState["AddHotelResultButton"] as bool?;
    if (addHotelResultButton.HasValue && addHotelResultButton.Value)
    {
        AddHotelResultButton();
    }
}

protected void Timer1_Tick(object sender, EventArgs e)
{
    ViewState["AddHotelResultButton"] = true;
    AddHotelResultButton();
}

protected void AddHotelResultButton()
{
    Timer1.Enabled = false;
    Label1.Text = DateTime.Now.ToString();
    Label2.Text = DateTime.Now.ToString();
    Label3.Text = DateTime.Now.ToString();
    ImageButton testbtn = new ImageButton();
    testbtn.ID = "testbtnid";
    testbtn.Click += new System.Web.UI.ImageClickEventHandler(this.imgBtn_Click);
    testbtn.ImageUrl = "images/heroAccent.png";
    PlaceHolder1.Controls.Add(testbtn);
}
