如何在ASP.NET中实现AJAX文件下载 [英] How to implement a file download in ASP.NET AJAX

问题描述

我想使用标准的ASP.NET文件下载的反应，像的在其他堆栈溢出问题。

I would like to use standard ASP.NET file download response, like in other Stack Overflow question.

Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition","attachment; filename=logfile.txt");
Response.TransmitFile( Server.MapPath("~/logfile.txt") );
Response.End();

但更新面板里面不起作用。我要做的，我会得到一个文件，如果被触发更新面板内的下载事件？

But inside update panel it does not work. What I have to do, that I will get a file if the download event is triggered inside update panel?
