Handling ASP buttons in MVC

ASP is not ASP.NET. And, you can't. There are no server controls in MVC. You emit html, and then you can do one of several things.

1 - put submit buttons on your form, and add a 'Command' attribute and a string parameter named Command to your HttpPost version of your controller method to see what was called.

2 - Make AJAX requests using JSON and jQuery, which can then call methods you write in your controller directly, with a method signature conforming to your JSON variables.
