今天在编写到处excel按钮时遇到了下面的错误：

Microsoft JScript 运行时错误: Sys.WebForms.PageRequestManagerParserErrorException: 无法分析从服务器收到的消息。之所以出现此错误，常见的原因是: 在通过调用 Response.Write() 修改响应时，将启用响应筛选器、HttpModule 或服务器跟踪。

详细信息: 分析附近的“<div>

   <table cells”时出错。

 

解决方案如下（我使用的是第二种，加入trigger）:

There are a number of ways of doing this:

1.The easiest is to simply place the button outside of any UpdatePanels. Unfortunately the layout of your page might not allow for this.

2.Add a PostBackTrigger to your UpdatePanel that points at the button. This works great if the button is declared statically through markup on the page.

3.Call ScriptManager.RegisterPostBackControl() and pass in the button in question. This is the best solution for controls that are added dynamically, such as those inside a repeating template.
