public class Address { public string Line1 { get; set; } public string Line2 { get; set; } public string City { get; set; } public string PostalCode { get; set; } public string Country { get; set; } } } public enum Role { Admin, User, Guest } I have also defined a Home controller, as shown in Listing 24-2. This controller defines a collection of sample Person objects and defines the Index action, which allows me to select a single Person by the value of the PersonId property. Listing 24-2. The Contents of the HomeController.cs File using System.Linq; using System.Web.Mvc; using MvcModels.Models; namespace MvcModels.Controllers { public class HomeController : Controller { private Person[] personData = { new Person {PersonId = 1, FirstName = "Adam", LastName = "Freeman", Role = Role.Admin}, new Person {PersonId = 2, FirstName = "Jacqui", LastName = "Griffyth", Role = Role.User}, new Person {PersonId = 3, FirstName = "John", LastName = "Smith", Role = Role.User}, new Person {PersonId = 4, FirstName = "Anne", LastName = "Jones", Role = Role.Guest} }; public ActionResult Index(int id) { Person dataItem = personData.Where(p => p.PersonId == id).First(); return View(dataItem); } } } I have created a view file called /Views/Home/Index.cshtml to support the action method. You can see the contents of this file in Listing 24-3. I have used the templated display helper to show some of the property values of the Person view model. Listing 24-3. The Contents of the /Views/Home/Index.cshtml File 634
@model MvcModels.Models.Person @{ ViewBag.Title = "Index"; Layout = "∼/Views/Shared/_Layout.cshtml"; } Person ID:@Html.DisplayFor(m => m.PersonId) First Name:@Html.DisplayFor(m => m.FirstName) Last Name:@Html.DisplayFor(m => m.LastName) Role:@Html.DisplayFor(m => m.Role) Finally, I created the Views/Shared folder and added a layout called _Layout.cshtml to it, the contents of which can be seen in Listing 24-4. Listing 24-4. The Contents of the _Layout.cshtml File @ViewBag.Title label { display: inline-block; width: 100px; font-weight: bold; margin: 5px; } form label { float: left; } input.text-box { float: left; margin: 5px; } button[type=submit] { margin-top: 5px; float: left; clear: left; } form div { clear: both; } @RenderBody() Understanding Model Binding Model binding is an elegant bridge between the HTTP request and the C# methods that define actions. Most MVC Framework applications rely on model binding to some extent, including the simple example application that I created in the previous section. To see model binding at work, start the application and navigate to /Home/Index/1. The result is illustrated in Figure 24-1. 635
