Before anyone asks, I need to support IE8 for various reasons. I've seen multiple solutions to this that stick a file upload control inside a form element and then utilise an iframe to simulate an AJAX file upload(Such as How to make Asynchronous(AJAX) File Upload using iframe?). However, in a Webforms project where you cannot have multiple form tags and I don't want to post the entire page, what is the best solution?
Cheers
