在自动回传上载文件 [英] Upload file on Autopostback

问题描述

你好，

我想知道是否有人可以帮助我.我有一个Web表单，可以在其中将数据输入给定文件，其中一些文件会自动回发.我还有两个上传功能，可以在其中将文件上传到表单上.
但是，每次我上载文件并执行自动回发操作时，似乎都会完全删除该文件.
有没有一种方法可以使自动回发不删除上传的文件?

这是我的上传代码:

Hi there,

I wonder if anyone could help me. I have a web form where i can enter data into given fileds some of them are on autopost back. I also have two upload functions where i can be able to upload files onto the form.
But everytime i upload the files and do something autopostback seems to be removing the file completely.
Is there a way so that autopostback does not remove the uploaded file?

Here is my upload code:

<pre lang="css"><asp:FileUpload ID="FileUpload1" runat="server" Style="z-index: 117; left: 458px;<br />
                position: absolute; top: 31px" /></pre><br />

在此先感谢

Thanks in advance
