在“设计”视图中双击Timer对象以创建_tick处理程序。

protected void My_Timer_Tick(object sender, EventArgs e)
{
    My_Timer_Name.Enabled = false;
    My_Page_Load_Function(); // Function created in step 1 above)
}

protected void My_Page_Load_Function()
{
    System.Threading.Thread.Sleep(5000); // A delay to simulate doing something.
    lblMyLabel.Text = "Done!";  // Write output to page. 
}

在javascript pageLoad()函数中,使用Ajax的PageMethods回调页面。

   function pageLoad(sender, args) {
                PageMethods.getVersions(LoadVersionsCallback);
    }

   [System.Web.Services.WebMethod]
    public static string getVersions()
    {
      StringBuilder sb = new StringBuilder();
       ... etc.
      return sb.ToString();

    }

   function LoadVersionsCallback(result) {
    // do something with the results - I load a dropdown list box.

   ...etc. 
    // here is where you hide your div holding the Ajax.gif  

   }

我会在页面上放置一个Ajax计时器,并将其设置为不到一秒。..它只会运行一次,在第一次勾选后,您需要禁用它,否则它将再次启动。(你不想多次启动你的长期运行过程……)
