I've had good luck with the obout.com file upload progress bar.

The alternative would be to create your own upload form using an iFrame and javascript, which can be found here.

I have used it more then 2 years ago. The web site as a couple of example for you to quickly integrate it into your own application. You won't have to use the file upload component that is provided with VS anymore.

There is a user manual on the Neat Upload site with code examples.
