ASP.NET MVC 4 Model property value lost coming back from Edit view - asp.net-mvc

Question

I have a model with a DateCreated value that is not scaffolded. Coming to GET Edit controller action I see that the model has a correct value that is passed on to the Edit view. Coming back from the view, POST method, the value for DateCreated is DateTime default. It's lost.
Does anyone know why? Controller and View are scaffolded.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(Product product)
{
try
{
if (ModelState.IsValid)
{
product.DateEdited = DateTime.Now;
db.Entry(product).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
}
catch (DataException dex)
{
Console.Write(dex.Message);
ModelState.AddModelError("", reg6.Resources.UnableToSaveChanges);
}
return View(product);
}
#model reg6.Models.Product
#{
ViewBag.Title = "Edit";
}
<h2>Edit</h2>
#using (Html.BeginForm()) {
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<fieldset>
<legend>Product</legend>
<table>
<tr>
<td>
<div class="editor-label">
#Html.LabelFor(model => model.Name)
</div>

Answer 1

In your view place a hidden element for the DateCreated
#Html.HiddenFor(m=>m.DateCreated)
All the hidden elements will be posted to the server.
