AsyncUpload is really come in handy, however I have a question which I don't know how to deal with:
I have a page with AsyncUpload control and other normal text fields for user to update/insert a article with attachment, and I only want to save file after user click 'Save' button (so not only for saving file but other text fields as well), however the attachment is uploaded asynchronously, so a file is uploaded before user click 'Save' button, so my questions is how to remove the file if user decide not to save page or even close browser ?
Many thanks!
