解决方案

使用UpdatePanel并在ajax完成UpdatePanel之后调用Javascript函数

使用SignalR实现它的最佳方法。它完全免费下载。我们已将此用于类似场景。

它有一个包装好的Web Socket功能来满足这些情况。或者您可以直接使用Web套接字：

以上是它的直接方式，但仍然有以下替代方案。



如果您使用的是4.5版本，那么你可以尝试以下方式。



。从代码需要使用需要联系到DB并等待响应的Async和Await。如果它得到了DB更新发生的响应，那么可以显示弹出窗口

。它应该是一个递归调用。我的意思是它需要通过异步调用保持开放的通信。一旦等待时间结束，另一个请求应该转到数据库。

。使用Thread或.Net的Background_Worker类可以完成同样的工作

。关键是我们需要让Thread或Background_Worker运行递归。

最简单的解决方案。



- 实现更新逻辑，更新结束后输入以下行。

回复.Write（ < script type ='text / javascript'>）; 
 Response.Write（  alert（'数据库更新成功。'）;）; 
 Response.Write（ < / script>）;

Use UpdatePanel and call a Javascript function after on ajax complete of UpdatePanel

The best way to get it implemented by using the SignalR. It is completely free to download. We have used this for similar scenarios.
Here is the url:

It is having a wrapped Web Socket functionality to meet these kind of cases. Or you can directly go for Web Sockets:

http://msdn.microsoft.com/en-in/library/ie/hh673567(v=vs.85).aspx[^]

The above are the direct ways for it but still there are alternatives as below.

If you are using the 4.5 version, then you can try the following way.

. From code need to use the Async and Await which need to contact to the DB and wait for a response. If it has got a response that an update happened in DB then can show the popup
. It should be a recursive call. I mean it need to keep open the communiction alive with the async call. Once the wait time is over another one request should go to the db.
. The samething can be done using Thread or .Net''s Background_Worker class
. The key thing is that we need to have the Thread or Background_Worker to run recursive.

Here you can see how to use Async: http://msdn.microsoft.com/en-us/library/vstudio/hh191443.aspx[^]

Hope this helps.

Thank You,

Simplest solution.

-Implement your update logic and after the update ends put the below lines.

Response.Write("<script type='text/javascript'>");
Response.Write("alert('Database updated succesfully.');");
Response.Write("</script>");
