FileUpload and Ajax

[Chen.Fisher]

Hi,

I'm using .Net 2.0, Ajax extension.

I'm trying to use the FileUpload and Ajax so the file upload will post itself and not the whole page. It doesn't work.

I read somewhere that there is no Ajax support for FileUpload control yet. Is that right?

I want the user to upload a file and see an animated gif as the progress bar while the file is uploading.

I'd heard it's not possible and read just yesterday that with Microsoft's Atlas/ Ajax Beta it's NOT possible, due to how the XMLHttpRequest object handles connections.

FileUpload and some other controls are not compatible with ajax extensions. You can revise at http://ajax.asp.net/docs/overview/UpdatePanelOverview.aspx

However, you can use iframes to make ajax-like file upload system, and make it work with ajax extensions. Here are my blog posts which also includes downloadable source code:

You can easily add javascripts to show and hide your animated image, when button is clicked and after process is complete (in RegisterStartupScript method)
