    <p>I'm using RC1 of ASP.NET MVC.</p> <p>I'm trying to extend <a href="http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx" rel="nofollow noreferrer">Phil Haack's</a> model binding example. I'm trying to use the default model binder to bind the following object:</p> <pre><code>public class ListOfProducts { public int Id { get; set; } public string Title{ get; set; } List&lt;Product&gt; Items { get; set; } } public class Product { public string Name { get; set; } public decimal Price { get; set; } } </code></pre> <p>I'm using the code from Phil's example with some alterations:</p> <p>Controller:</p> <pre><code>using System.Collections.Generic; using System.Web.Mvc; namespace TestBinding.Controllers { [HandleError] public class HomeController : Controller { public ActionResult Index() { ViewData["Message"] = "Welcome to ASP.NET MVC!"; return View(); } //Action method on HomeController public ActionResult UpdateProducts(ListOfProducts productlist) { return View(productlist); } } public class Product { public string Name { get; set; } public decimal Price { get; set; } } public class ListOfProducts { public int Id { get; set; } public string Title { get; set; } List&lt;Product&gt; Items { get; set; } } } </code></pre> <p>View:</p> <pre><code>&lt;%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %&gt; &lt;asp:Content ID="indexHead" ContentPlaceHolderID="head" runat="server"&gt; &lt;title&gt;Home Page&lt;/title&gt; &lt;/asp:Content&gt; &lt;asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"&gt; &lt;form method="post" action="/Home/UpdateProducts"&gt; &lt;input type="text" name="productlist.id" value="99" /&gt; &lt;input type="text" name="productlist.Title" value="SomeTitle" /&gt; &lt;input type="hidden" name="productlist.Index" value="0" /&gt; &lt;input type="text" name="productlist.items[0].Name" value="Beer" /&gt; &lt;input type="text" name="productlist.items[0].Price" value="7.32" /&gt; &lt;input type="hidden" name="productlist.Index" value="1" /&gt; &lt;input type="text" name="productlist.Items[1].Name" value="Chips" /&gt; &lt;input type="text" name="productlist.Items[1].Price" value="2.23" /&gt; &lt;input type="hidden" name="productlist.Index" value="2" /&gt; &lt;input type="text" name="productlist.Items[2].Name" value="Salsa" /&gt; &lt;input type="text" name="productlist.Items[2].Price" value="1.23" /&gt; &lt;input type="submit" /&gt; &lt;/form&gt; &lt;/asp:Content&gt; </code></pre> <p>My problem is that the simple types (Id and Title) appears in the productlist object, but not the List. So:</p> <ul> <li>Is my code bad (wouldn't be surprised)?</li> <li>Can the default model binder handle the ListOfProducts objects?</li> <li>If the default model binder won't handle this type of object what do I need to do (examples if possible)?</li> </ul> <p>Thanks in advance.</p>

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.

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