Jon Galloway already had some interesting thoughts about uploading large files with ASP.NET. Unfortunately he didn’t really advise on one good solution.
So I decided (or had) to take a look myself. What I needed is an upload button with a progress bar that works on a Mac and on a PC with a reasonable recent browser.
And here are the results:
Convincing Solutions: (They normally worked on IE, but not necessarily on Mac)
A bit a confusing product palette and pricing, but looks like it starts at $79 plus $19 for the progress bar. Or $499 with Source Code. Demo works fine. Web-Site looks a little unprofessional.
Component seems to work fine, nice progress bar and decent pricing for $338. Homepage works a bit strange, but info is there. No success on Mac.
Nice simple online Demo and webpage. Starts at $149. Progress Bar updates nicely with infos about uploaded kBytes and time remaining. Forum has posts and lots of views. Last update was on the 06/24/2007. Works on Mac Safari, FF and on Windows.
Dart File Upload for ASP.NET
Looks professional and the online Demo works fine. Nice progress bar with additional information. Skinning possibilities and a special File Dialog button, so you don’t see the “Browse” button. Starts at $249.
Progress Bar does not really move on Safari or FF on Mac.
Essential Objects Ajax Uploaded
Another nice component with a good online Demo. Pricing starts at $149. Multiple Postback options and different skinning possibilities. Works fine in all tested browsers.
Telerik RadUpload Promoetheus
Telerik is a big provider of ASP.NET components with a pretty good reputation as far as I know. Their Upload component seems to be one of the more powerful on this list. The individual control starts at $249 and the whole suit is $799.
Based on this info, I decided to give it a try. Unfortunately, it does not currently work in Integrated Mode with IIS 7. Neither does the Progress Bar work in Safari 3 on a Mac 10.5.1 (Leopard). Very disappointing.
Not so convincing Solutions: (Demo’s did not work on my Vista IE7)
Look more like a hobbyist component, also, no updates since a while, no forum, etc. On the other hand, it’s only $49.
Update: Original Link does not work anymore: http://www.datanyms.com, but got a comment with a new Link to expanData AND a new price, now its $999. I tested it again. Looks like the demo is still the old one. It works fine in IE, but still not in Safari.
The only one that even mentions Ajax Panel compatibility, other than that, not much there. No Progress Bar either. $69 is ok. Last update was on May 2007.
For $499 from SoftArtisans. There is no Progress Bar, at least in the Online Demo. Rather weak online presentation, but seems to be one of the players in the Upload Component Area.
With $199 in the middle field if it comes to pricing. Demo works fine, but the Progress Bar clearly reloads after each update and runs in a Popup. There are better solutions out there.
One of the more expensive tools for $899. The Upload happens in Popup Window, which I don’t really like too much, also the price is pretty high and I’ve never heard from this company before.
Starts at $310 and goes up to $3625 for a Corporate License. Progress Bar is in a Popup, but did not work in my test.
Only $50, but no online demo or forum available, so I didn’t test this any further.
Again only $50, but looks like there has been no update since 2006, not really a good candidate either. Demo works fine though.
Looks like a pretty cool Open Source Component. The Progress Bar is in an IFrame and seems to do its job, but the update steps are not very fine grained. Also supports Mono!
Unfortunately it also does not work with Integrated Mode in IIS7. Please help voting so that Microsoft fixes this issue.
Passed the test in all my browsers (Mac and PC). Forum is full and recent, support seems to be available.
The only Flash based component in this test. Was my longtime favorite and still is to a certain degree. We used this for Supertext for a while now. Really like the architecture and the features, unfortunately we had many users for which it didn’t work. Would be my first choice for an Intranet solution or if you have a limited user base.
Didn’t see much Ajax or even a Progress Bar on my quick test, but does have decent amount of online examples.
Forum has tons of posts and latest version is from the 7/27/2007.
Looks like this is rather a helper component to handle uploaded files, than something like the other tool that come with progress bars. etc.
Multiple File Upload With Progress Bar Using Flash and ASP.NET
From the Codeproject Website. Got really good reviews, but didn’t get around to try it out yet.
HORRIBLE! More than half of the products don’t really work, most of them don’t do anything on a Mac. Not sure why this has to be such an issue. Is this only an IIS/ASP issue?
The only 3 Components that really worked in our quick tests were SlickUpload, Essential Objects and NeatUpload. We kinda liked SlickUpload, but decided to give NeatUpload a try. Will keep you posted about the results.
Would really love to hear what experiences that other people had?
