    <p>I'm working with ASP.NET MVC 4 and I have the following models:</p> <pre><code>public class MultiLanguageText { [Key] public int Id { get; set; } [Required] public string Name { get; set; } public virtual ICollection&lt;LocalizedText&gt; LocalizedTexts { get; set; } } public class LocalizedText { [Key] public int Id { get; set; } [ForeignKey("Language")] public int LanguageId { get; set; } public virtual Language Language { get; set; } [ForeignKey("MultiLanguageText")] public int MultiLanguageTextId { get; set; } public virtual MultiLanguageText MultiLanguageText { get; set; } public string Text { get; set; } } </code></pre> <p>I'm trying to create an Edit view for <code>MultiLanguageText</code> which will also contain an editor for every item in the <code>LocalizedTexts</code> property. The form goes like this:</p> <pre><code>@using (Html.BeginForm("Edit", "MultiLanguageText", FormMethod.Post)) { @Html.ValidationSummary(true) &lt;fieldset&gt; &lt;legend&gt;MultiLanguageText&lt;/legend&gt; @Html.HiddenFor(model =&gt; model.Id) &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; @Html.EditorFor(model =&gt; model.LocalizedTexts) &lt;p&gt; &lt;input type="submit" value="Save" /&gt; &lt;/p&gt; &lt;/fieldset&gt; } </code></pre> <p>The editor template I've created (in the file <code>~/Views/Shared/EditorTemplates/LocalizedText.cshtml</code>) is the following:</p> <pre><code>&lt;fieldset&gt; &lt;legend&gt;LocalizedText&lt;/legend&gt; @Html.HiddenFor(model =&gt; model.Id) &lt;div class="editor-label"&gt; @Html.LabelFor(model =&gt; model.LanguageId) &lt;/div&gt; &lt;div class="editor-field"&gt; @Html.EditorFor(model =&gt; model.LanguageId) @Html.ValidationMessageFor(model =&gt; model.LanguageId) &lt;/div&gt; &lt;div class="editor-label"&gt; @Html.LabelFor(model =&gt; model.MultiLanguageTextId) &lt;/div&gt; &lt;div class="editor-field"&gt; @Html.EditorFor(model =&gt; model.MultiLanguageTextId) @Html.ValidationMessageFor(model =&gt; model.MultiLanguageTextId) &lt;/div&gt; &lt;div class="editor-label"&gt; @Html.LabelFor(model =&gt; model.Text) &lt;/div&gt; &lt;div class="editor-field"&gt; @Html.EditorFor(model =&gt; model.Text) @Html.ValidationMessageFor(model =&gt; model.Text) &lt;/div&gt; &lt;/fieldset&gt; </code></pre> <p>I'm testing with some pre-existing values and all the data is shown properly in the parent and in the child editors, when the page is shown. However, when I submit the form, all changes done inside any of the child editors are ignored.</p> <p>My <code>HttpPost</code> method is this:</p> <pre><code> [HttpPost] public ActionResult Edit(MultiLanguageText multilanguagetext) { if (ModelState.IsValid) { db.Entry(multilanguagetext).State = EntityState.Modified; db.SaveChanges(); return RedirectToAction("Index"); } return View(multilanguagetext); } </code></pre> <p>My question is: <strong>How do I make it so that all values are posted, from both the parent model and its children model editors?</strong> (I've seen that other similar questions exist, but I've tried their solutions and they didn't seem to fix my problem.)</p>

    1. COCould you provide a little more information? What do the posted key/value pairs look like? Is the collection being populated, but with default values? Or is it empty? Or is it null?

    2. COI'm testing with seeded values, in which the collection is not empty. Data is retrieved successfully from the database. The editor templates show up properly and with the correct values. The problem is that any changes in the collection are not saved when submitting he form.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
