File Upload - ASP.NET MVC

This is a basic example of instantiating the file upload using the ASP.NET MVC helper.

This sample is designed for a larger screen size.

On mobile, try rotating your screen, view full size, or email to another device.

Note: For demonstration purposes, uploaded files must be smaller than 1 MB; however, the control can be used with any file size supported by the server/client (usually up to 2GB). Any files you upload on this page are not retained on our servers.
