    copied!<p>I have this classes who is mapped using Entity Framework Code First:</p> <pre><code>public class Person { public int PersonId { get; set; } public string Name { get; set; } //... additional properties [Required] public virtual ICollection&lt;Address&gt; Addresses { get; set; } } public class Address { public int AddressId { get; set; } public string Street { get; set; } //... additional properties public int PersonId { get; set; } public virtual Person Person { get; set; } } </code></pre> <p>So, using ASP.NET MVC 3, how can I perform the Edit View for Person to fill all Person properties within an Address in just one Form?</p> <pre><code>@using (Html.BeginForm()) { @Html.ValidationSummary(true) &lt;fieldset&gt; &lt;legend&gt;Person&lt;/legend&gt; &lt;div class="editor-label"&gt; @Html.LabelFor(model =&gt; model.Name) &lt;/div&gt; &lt;div class="editor-field"&gt; @Html.EditorFor(model =&gt; model.Name) @Html.ValidationMessageFor(model =&gt; model.Name) &lt;/div&gt; &lt;div class="editor-label"&gt; @Html.LabelFor(model =&gt; model.Adresses.FirstOrDefault().Street) &lt;/div&gt; &lt;div class="editor-field"&gt; @Html.EditorFor(model =&gt; model.Adresses.FirstOrDefault().Street) @Html.ValidationMessageFor(model =&gt; model.Adresses.FirstOrDefault().Street) &lt;/div&gt; &lt;p&gt; &lt;input type="submit" value="Create" /&gt; &lt;/p&gt; &lt;/fieldset&gt; } </code></pre> <p>This works fine to show the inputs with Street from database, but when I do the submit, the Street doesnt change.</p> <pre><code>[HttpPost] public ActionResult Edit(int id, FormCollection formCollection) { Person person = unityOfWork.PersonRepository.GetById(id); UpdateModel&lt;Person&gt;(person); if (ModelState.IsValid) { unityOfWork.PersonRepository.Update(person); unityOfWork.SaveChanges(); return RedirectToAction("Index"); } return View(person); } </code></pre>
