File upload - button only, with postback????

Hi.

I'm creating a page where users can upload files using the .Net 2 FileUpload component (hopefully!!)

I understand that this is similar to the input type of 'file', and that you're supposed to select a file, and then have a seperate button for submitting and therefore uploading, but I find this particularly ugly.

I simply want a browse button that pops up the FileUpload's 'browse' dialog, and then uploads the file if the user clicks 'okay', therefore allowing me to handle the server side stuff and save the file etc..

The closest I have got to this is a button that clicks a 'hidden' FileUpload control, and then does a postback via JavaScript, but this does not work - you get an 'access denied' error, caused by the FileUpload not having a file.

If you get what I'm asking for, can someone please let me know if this is possible, without having to code the upload myself.  (I've done this before when coding with pure ASP, not .Net, and would rather not have to do it, especially since the FileUpload component already does most of what I need!!!)

Thanks in advance,

John.
