title: display validation errors using @html.validationmessagefor
body: <p>I'm trying to use <code>@Html.ValidationMessageFor()</code> for displaying errors in MVC,
  and I'm trying to do something like: <code>@Html.ValidationMessageFor(@ViewBag.Price)</code> but I get syntax errors.
  I want validation for this input:</p>
  
  <p><code>input type="number" value="@ViewBag.Price"  name="CurrentPrice"</code></p>
