How to implement file upload progress bar on web? I would like display something more meaningful that animated gif while users upload file to my web application. What possibilities do I have? Edit: I am using .Net but I don't mind if somebody shows me platform agnostic version. Solution: Here are a couple of versions of what you're looking for for some common JavaScript toolkits.
