Master-Detail Sample Code for MVC 3 Razor (using Ajax for details)

Question

I am looking for sample code to create a master/details with c# mvc 3.

Specifically, I am trying to figure out how to call via ajax the rendering of a partial view. I am able to put the partial view on the form but want to populate it after a user has selected an item from a select list via ajax.

thx

As always you start with the model:

public class MyViewModel
{
    public int Id { get; set; }
    public string Title { get; set; }
}

public class DetailsViewModel
{
    public string Foo { get; set; }
    public string Bar { get; set; }
}

then a controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        // TODO: don't hardcode, fetch from repository
        var model = Enumerable.Range(1, 10).Select(x => new MyViewModel
        {
            Id = x,
            Title = "item " + x
        });
        return View(model);
    }

    public ActionResult Details(int id)
    {
        // TODO: don't hardcode, fetch from repository
        var model = new DetailsViewModel
        {
            Foo = "foo detail " + id,
            Bar = "bar detail " + id
        };
        return PartialView(model);
    }
}

and corresponding views.

~/Views/Home/Index.cshtml:

@model IEnumerable<MyViewModel>

<ul>
    @Html.DisplayForModel()
</ul>

<div id="details"></div>

<script type="text/javascript">
    $(function () {
        $('.detailsLink').click(function () {
            $('#details').load(this.href);
            return false;
        });
    });
</script>

~/Views/Home/Details.cshtml:

@model DetailsViewModel
@Model.Foo
@Model.Bar

~/Views/Home/DisplayTemplates/MyViewModel.cshtml:

@model MyViewModel
<li>
    @Html.ActionLink(Model.Title, "details", new { id = Model.Id }, new { @class = "detailsLink" })
</li>

I have blogged about creating master detail form using asp.net mvc where you can add n child records on clietn side without the need of sending ajax request just to bring the editor fields for child records. it used jquery templates
