Multiple File Selection For Uploading in ASP.NET

Question

There are several resources available on net to upload multiple files, but using multiple FileUpload controls. What I need to have multiple file selection dialog box so that user can select multiple files at one shot and then all files should be uploaded on one click.

Anyone of you have any idea?

Thanks in advance.

Answer 1

You should know that this is impossible using just the normal html and javascript code, due to security issues in the browsers.

To do that you will need to use another external way such as:

Flash -> SwfUpload, FancyUpload

Applet

ActiveX

Silverlight

Answer 2

You may want to check out the Flajaxian controls - http://www.flajaxian.com/. They give you the ability to select multiple files at once for upload, and the control is free.

Answer 3

I'm pretty sure you'd have to do this with a Java applet (or ActiveX control) that pops up a file open dialog and then assigns each of the file names selected to a hidden FileUpload HTML control.
