C＃的UpdatePanel计时器的Page_Load [英] c# updatepanel with timer page_load

问题描述

我尝试用一​​些AJAX了。我有出现在我的母版，其中有一个更新面板和一个计时器自定义控件。计时器火灾和面板更新，一切都是花花公子。除了有一些操作，我不希望它在每次刷新时执行。这似乎是整个页面生命周期发生在每次刷新。存在变数我想设置，并保持其价值的刷新。有没有一种方法，使之只执行什么在timer_tick电话吗？

I'm experimenting with some AJAX now. I have a custom control which appears on my masterpage in which there is an update panel and a timer. The timer fires and the panel updates and everything is dandy. Except that there are some operations that I don't want it to perform on every refresh. It seems like the entire page lifecycle happens with each refresh. There are variables I want to set, and keep their value on the refresh. Is there a way to make it perform ONLY what's in the timer_tick call?

推荐答案

不知道什么是AJAX.Net后回看起来像，但我通常保护我的其他控件和内容检查后回来;

Not sure what what an AJAX.Net post back looks like to, But I usually protect my other controls and content by checking for post back;

protected void Page_Load(object sender, EventArgs e)
{

     // if its a post back then my controls should already be setup... 
     if (!Page.IsPostBack)
     {
          InitControlData();
     }    
}

，然后将其应属于通到你的事件处理？

and then it should fall thru to your event handling?

protected void timer_tick(object sender, EventArgs e)
{
    // Do my Ajaxy work~
}
