fileupload有文件问题 [英] fileupload has file problem

问题描述

更新面板问题与文件upload.but文件上传超出更新面板。文件上传文件始终为false。

update panel problem with file upload.but file upload out of update panel. file upload has file is always false.

推荐答案

这是因为Form的encType属性。

你需要设置

It is because of Form's encType attribute.
you need to set

encType = "multipart/form-data"

在您的控件的Init evet中尝试此代码。它会将encType属性添加到页面上的表单中，然后您可以在FileUpload Control中接收文件字节。

Try this code inside Init evet of your control. It will add the encType attribute to the form you have on your page and then you may receive file bytes inside FileUpload Control.

ScriptManager.RegisterStartupScript(page, page.GetType(), Guid.NewGuid().ToString() + new Random().ToString().Replace(".", ""), "

（'＃yourFormID'）。attr（'enctype'，'multipart / form-data'）;，< span class =code-keyword> true ）;

('#yourFormID').attr('enctype', 'multipart/form-data');", true);

注意：您需要在页面上引用JQuery或者使用javascript来完成这项工作。



祝你好运：）

Note: you need to have JQuery referenced onto your page or alternatively use javascript to do this job.

Good luck :)
