copied!<p>I have a HiddenFor field that is missing it's value tag. This is on a MVC4 project using the razor view engine.</p> <pre><code><input name="Id" id="teamId" type="hidden" data-val-required="The Id field is required." data-val-number="The field Id must be a number." data-val="true"/> </code></pre> <p>This is generated from:</p> <pre><code>@Html.HiddenFor(m => m.Id, new { id = "teamId" }) </code></pre> <p>From my model (using System.ComponentModel.DataAnnotations):</p> <pre><code>public class TeamModel { public int Id { get; set; } [Required(ErrorMessage = "Please enter a team name"), MaxLength(25)] public string Name { get; set; } } </code></pre> <p>When passing a new model to the form I've even tried manually setting the Id field like so:</p> <pre><code>return PartialView("EditTeam", new TeamModel{Id = 5}); </code></pre> <p>This still doesn't display a value however. Oddly it's passing client validation but failing server side validation. I have a similar setup in another project which works fine. I can't see any differences between them. Is there something obvious that I've missed? Thanks :)</p> <p>edit: If I use:</p> <pre><code>@Html.Hidden("test", Model.Id) </code></pre> <p>It works. Something with the HiddenFor is setting the value to blank (seeing the raw HTML the value field is there but just set to: value="")</p> <p>edit: For completeness sake, here is the controller (also the root of the problem):</p> <pre><code>public ActionResult GetTeam(int? id) { return PartialView("EditTeam", id.HasValue ? _teamLogic.GetById(id.Value) : new TeamModel()); } </code></pre>
