Code:

@model MyMVCApp.Models.Surveyor
@{
ViewBag.Title = "Log in";
Layout = "~/Views/Shared/_LayoutPage1.cshtml";
}
<h1>@ViewBag.Title</h1>
@using (Html.BeginForm()) {

@Html.ValidationSummary(true)

<fieldset>
<legend>Log in Form</legend>

@Html.LabelFor(m => m.SurveyorName)
@Html.TextBoxFor(m => m.SurveyorName)
@Html.ValidationMessageFor(m => m.SurveyorName)

What's in the controller?
Did you check if Model.IsValid?

Code:

  
        public ActionResult Login() 
        {
            //ViewResult v = new ViewResult();
            //v.ViewName = "~/Views/Account/Login.cshtml";
            return View();
        }

        [HttpPost]
        public ActionResult Login(Surveyor s)
        { 
            return RedirectToAction("Registered"); 
        }

1. When the user submits the form (i.e. does a POST request), your [HttpPost] Login action will be called.
2. Before that ModelBinder creates an instance of "Surveyor"-class and tries to extract values from your form and put them into properties of that class
3. And then... nothing.
The request is automatically redirected to another action - to the "Registered"-action - regardless of what was there in the submitted form.

You need to do something. What exactly - I don't know. May be look up this object in the database and if it exists there - then allow to proceed.

Anyway, this code is not from the book, so I cannot tell you exactly what to do next.

Of course - there is no reason for the validation messages to appear because you are not validating your model.

You need something like:

if (Model.IsValid)
{ // Save your data }
else
{ return View(); }

here is my code

Code:

if (ModelState.IsValid)
            {
                SurveyContext sc = new SurveyContext();
                sc.Surveyor.Add(s);
                sc.SaveChanges();
            }
            return RedirectToAction("Registered");

it's going to "Registered" action instead showing validation messages
