如何在PostBack之后维护FileUpload Control的url。 [英] How to Maintain FileUpload Control’s url after PostBack.

问题描述

嗨


i有10个文件上传控件和10个文本框，文本框更改事件autopostback为true。

一旦用户选择文件上传控件和任何文件当页面的回发事件发生时选择，文件上传控制松开它的值。对于我来说，保持FileUpload Control的状态非常烦人。我搜索了很多文章和网站，但没有得到任何固定的解决方案。然后我决定自己做，并为其他开发者发布。这是许多开发人员非常普遍的问题。

Hi
i have 10 fileupload control and 10 textbox which have textbox change event autopostback true.
Once user select files in file upload controls and in any selection when page’s post back event occurs, file upload control loose it’s value. It was very annoying situation for me to maintain the state of FileUpload Control. I search around so many articles and sites but didn't get any fixed solution. Then I decided to do it myself and publish for other developers. This is very common problem with many developers.

推荐答案

当用户上传文件时保存immedaitley进入一些本地文件夹/保存在服务器中（创建临时文件夹）。页面刷新从本地文件夹/服务器临时文件夹中获取上载文件。一旦用户保存成功从本地文件夹/服务器临时文件夹中删除。
