The problem here is that ImageButton is added to the page only after timer tick. 这里的问题是ImageButton 仅在计时器滴答之后才添加到页面。 If you want server-side handlers to be invoked for such dynamically added controls, you have to added the to the page on every postback. 如果要为这种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将其添加到页面中。 Here is how it can be done using key view state: 使用键视图状态的方法如下：
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);
}

I would do it like this : 我会这样做：
Put your button inside your updatePanel and disable it
将按钮放入updatePanel并将其禁用 Put it as a trigger inside the
<triggers>tag将其作为触发器放在<triggers>标记内When the tick event come, enable your button
滴答事件到来时，启用您的按钮
