如何在ASP.NET和IE8中伪造异步（AJAX）文件上传？

Question

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?

Answer 1

I think if I correct you on one thing you already have the answer to your problem in the link you shared.

You can have only one server-side form , that does not mean you can not have a another html form on the page. Simply add one more form without runat=server tag.

Hope this helps.
