    <p><strong>Update:</strong> Example now uses a AJAX JSON POST</p> <p>If you must use an abstract type, you could provide a <a href="http://msdn.microsoft.com/en-us/library/system.web.mvc.imodelbinder.aspx" rel="noreferrer">custom model binder</a> to create the concrete instance. An example is shown below:</p> <p><strong>Model / Model Binder</strong></p> <pre><code>public abstract class Student { public abstract int Age { get; set; } public abstract string Name { get; set; } } public class GoodStudent : Student { public override int Age { get; set; } public override string Name { get; set; } } public class BadStudent : Student { public override int Age { get; set; } public override string Name { get; set; } } public class StudentBinder : IModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var values = (ValueProviderCollection) bindingContext.ValueProvider; var age = (int) values.GetValue("Age").ConvertTo(typeof (int)); var name = (string) values.GetValue("Name").ConvertTo(typeof(string)); return age &gt; 10 ? (Student) new GoodStudent { Age = age, Name = name } : new BadStudent { Age = age, Name = name }; } } </code></pre> <p><strong>Controller Actions</strong></p> <pre><code>public ActionResult Index() { return View(new GoodStudent { Age = 13, Name = "John Smith" }); } [HttpPost] public ActionResult Index(Student student) { return View(student); } </code></pre> <p><strong>View</strong></p> <pre><code>@model AbstractTest.Models.Student @using (Html.BeginForm()) { &lt;div id="StudentEditor"&gt; &lt;p&gt;Age @Html.TextBoxFor(m =&gt; m.Age)&lt;/p&gt; &lt;p&gt;Name @Html.TextBoxFor(m =&gt; m.Name)&lt;/p&gt; &lt;p&gt;&lt;input type="button" value="Save" id="Save" /&gt;&lt;/p&gt; &lt;/div&gt; } &lt;script type="text/javascript"&gt; $('document').ready(function () { $('input#Save').click(function () { $.ajax({ url: '@Ajax.JavaScriptStringEncode(Url.Action("Index"))', type: 'POST', data: GetStudentJsonData($('div#StudentEditor')), contentType: 'application/json; charset=utf-8', success: function (data, status, jqxhr) { window.location.href = '@Url.Action("Index")'; } }); }); }); var GetStudentJsonData = function ($container) { return JSON.stringify({ 'Age': $container.find('input#Age').attr('value'), 'Name': $container.find('input#Name').attr('value') }); }; &lt;/script&gt; </code></pre> <p><strong>Added to Global.asax.cs</strong></p> <pre><code>protected void Application_Start() { ... ModelBinders.Binders.Add(new KeyValuePair&lt;Type, IModelBinder&gt;(typeof(Student), new StudentBinder())); } </code></pre>

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).
