Hello, I'm attempting to have multiple buttons submit to the same ActionResult; however, the btn value is always null. What am I doing wrong? What could cause this issue?

//view
 @using (Html.BeginForm())
{
  <button type = "submit" name = "btn" value = "save_new" id = "SaveNew" > Save & amp; New </button>
  <button type = "submit" name = "btn" value = "save_close" id = "SaveClose" > Save & amp; Close </button>
}


//controller
        [HttpPost]
        public ActionResult TestUsers(TestUsersModel model, string btn)

        {
            if (btn == "save_new")
            {
                // the form was submitted using the Save&New button
            }
            else if (btn == "save_close")
            {
                // the form was submitted using the Save&Close button
            }
            else
            {
                UpdateModel(model.Grid.UpdateParams);
                return Json(model.GetRows());
            }
}

I don't see anything wrong, and a quick test here works the way you expect it to work. Is it possible something in the model conflicts with the btn binding?

It is working correctly now. There was another button in the view that does some JavaScript. I included that in the form and now it works. Don't know why that would matter...

That shouldn't matter, because elements outside the form are not sent to the server in HTTP POST. Could be some glitch that you corrected elsewhere. Anyway, glad you got it sorted out.
