Summary

So far we have seen two aspects in this article: how to upload a file using ASP.NET AJAX 1.0 extensions and how to display a please wait message during an AJAX style file upload. Both scenarios will be used very often in almost each web application. I hope you will use these techniques in your web pages.

What reason put this in UpdatePanel if you use PostBackTrigger? This is full PostBack!

I'm going to have to agree with the new guy on this one. Not exactly the "AJAX" experience that I'm sure everyone hoped for.

This is NOT AJAX. It just doing a full post back. If it's just post back without utilizing any AJAX...why would you need to put it into an update panel?

Great article, thanks ;)
:) Although I'm using this for my current project:
http://www.aurigma.com/Products/ImageUploader/default.aspx
The price is pretty steep though but it has yummy resize and thumbnailing along with other stuff that I don't need :)

Even though you are using UpdatePanel. It is not actually AJAX, it is posting synchronously all the time.

This method simply fakes an ajax postback and which might look cool but defeats the whole purpose of the ajax postback. Anyway, here is a link to a page that does it correctly, using an IFrame as Microsoft does in Hotmail.

Great, but take a look at the FileUpload AJAX control for ASP.NET hosted on codeplex (http://www.codeplex.com/fileuploadajax)

Hi all, I just try your method, but I have a form view all the field will be save to the database, among that, I have fileUrl file that contains the uploads filename, so I must put this upload file inside the form view. But it not working both update panel and update progress, I don't know why.
Title: Not working with gif IE7 solved

Sorry for the 3rd comment ;-) but I've found solution for IE7 here http://west-wind.com/WebLog/posts/1227.aspx:

add this to JavaScript:
setTimeout('document.images["Progressbar"].src = "progressbar_green.gif"', 200);

and set ID of the image to "Progressbar".

Thx for the article.

But I got a problem. Text (Label) is working OK but using gif e.g. from http://mentalized.net/activity-indicators/ doesn't work - it shows only a white place. Any idea?
Title: This is NOT a AJAX based File Upload Method

The method documented here does a full post-back and therefore the title of this article is misleading!
Title: why?   
Name: Mikal Schacht Jensen

Comment:
I've been attempting to upload files using ASP.NET ajax, and although I haven't spent much time exploring it, I always ended up having to do a full postback to actually be able to retrieve the file serverside. So when I first saw this article linked somewhere, I immediatly clicked over here.

I'm still a fairly inexperienced programmer with less than a year's paid programming under my belt. But having read it now, I fail to see the point of it all. Doesn't adding the button to a postbacktrigger make it cause a full postback, and thus defeat the entire purpose of using Ajax?
