Multiple File Selection For Uploading in ASP.NET

Question

Hi Friends,

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 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 2

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.

Answer 3

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

I can't comment on answers yet so i'm making a new answer to reply.

Paul McLean: thank you so much for providing the link! Flajaxian is great component and so easy to use.

IrfanRaza: you actually can get at the filename & stream for each file that is uploaded. Check out the Flajaxian documentation and follow their model for creating a FileUploaderAdapter. In the ProcessFile function you have access to the HttpPostedFile. The only problem i ran into was not having the proper mime type (its set to "application/octet-stream") but you can get around that by checking the extension to the file.
