FileUpload control inside an UpdatePanel without refreshing the whole page?

by

I know of a third party component that can do that. It’s called “swfupload“ and is free to use and open source, and uses javascript and flash to do the magic.

here is a list of the features they offer:
(from their site)

  • Upload multiple files at once by ctrl/shift-selecting in dialog
  • Javascript callbacks on all events
  • Get file information before upload starts
  • Style upload elements with XHTML and css
  • Display information while files are uploading using HTML
  • No page reloads necessary
  • Works on all platforms/browsers that has Flash support.
  • Degrades gracefully to normal HTML upload form if Flash or javascript is
    unavailable
  • Control filesize before upload starts
  • Only display chosen filetypes in dialog
  • Queue uploads, remove/add files before starting upload

They also have a demo area where you can play around with their control. That way you can make sure it is exactly what you want.

We used it in one of our projects and it has never failed us so far, so I think this is a safe bet.

oh and here is the download page: http://code.google.com/p/swfupload/
