2. Model – View - Controller Model Controller View

3. Controller – The Traffic Cop  Handles User Input  Interacts with Model/Data  Select View to Render

4. Controllers MVC - WebForm

5. ASP.NET Page Lifecycle

6. Request Flow Request HTTP Routing Route Route Handler Http Handler Controller View Engine View Response

7. Controllers – Page Routing

8. Controllers – Actions

9. Controllers – Defining Actions

10. Controllers – Parameters  RouteData: Contains Name/Value Pairs  Form, Query String, and/or Cookie  Missing Reference/Nullable Types set to null  Nullable optional parameters  Base class: Request and Response Methods

11. Controllers – Action Results  ViewResult  RedirectResult  RedirectToRouteResult  ContentResult  JsonResult  EmptyResult

12. Controllers – Attributes  PrincipalPermission  NonAction  ActionFilter

13. Controllers – Action Filters  Attach additional behaviors to actions  Before & After Action Execution  Before & After Result Execution  Useful for logging, compression, etc.

14. Controllers – Unit Testing

15. Testing Controller Actions  No requirement to test within ASP.NET runtime!  Use RhinoMocks, TypeMock, Moq, etc.  Create Test versions of the parts of the runtime you want to stub [TestMethod] public void ShowPostsDisplayPostView() { TestPostRepository rep = new TestPostRepository(); BlogController controller = new BlogController(rep); var result = controller.ShowPost(2); Assert.AreEqual("showpost", result.ViewName); Assert.IsTrue(repository.GetPostByIdWasCalled); Assert.AreEqual(2, repository.LastRequestedPostId); } [TestMethod] public void ShowPostsDisplayPostView() { TestPostRepository rep = new TestPostRepository(); BlogController controller = new BlogController(rep); var result = controller.ShowPost(2); Assert.AreEqual("showpost", result.ViewName); Assert.IsTrue(repository.GetPostByIdWasCalled); Assert.AreEqual(2, repository.LastRequestedPostId); }

16. ASP.NET MVC: Views

17. Model – View - Controller Model Controller View

18. Views – What are they?  Render output  Usually pretty “stupid”

19. It’s all about the “ViewData” Views - Working with Data

20. Views - Strongly-Typed Data  Inherits ViewPage  DEMO: Strongly-Typed View

21. Views - Weakly-Typed Data  Inherits ViewPage  DEMO: Weakly-Typed View

22. “I can see!” View Engines

23. View Engines - Definition  Figure out how to render the markup  View Locator finds the template  Pluggable  Web Forms, Nvelocity, Brail, Nhaml, etc.  Roll your own  Implement IViewEngine

24. View Engines - WebFormViewEngine  Default engine based on Web Forms markup  Familiar Environment  Layout:.master  Content:.aspx  User Controls:.ascx

25. View Engines - WebFormViewLocator  Standard, default layout: /Views /{Controller Name} /*.aspx /*.ascx /Shared /*.master /*.aspx /*.ascx

26. Think of them as your personal assistants. UI Helpers

27. Why do we need UI Helpers?  More control = less done for you  Avoid writing “boring” markup  Encapsulate what varies  Replace Web Forms server controls

28. Extension Methods Revisited  New.NET 3.0 feature  Static Methods posing as built-in behavior  Make your life a whole lot easier  Allow easy extensibility!

29. UI Helpers - Common/Useful Helpers Form HelpersUrl/Link/Content Helpers  Html.Hidden()  Html.TextBox()  Html.TextArea()  Html.RadioButton()  Html.RadioButtonList()  Html.DropDownList() method(name, value, attributes)  Html.ActionLink ()  Html.RouteLink()  Html.Encode()  Html.AttributeEncode()  Url.Action()  Url.RouteUrl()  Url.Encode(contentPath)  Url.Content(contentPath)

30. No, not … Back to basics! DEMO: Working with Forms

31. Rendering Components

32. User Controls  Extension Methods  Html.RenderUserControl(virtualPath)  Html.RenderUserControl(virtualPath, data)  Server Controls  Traditional Web Forms style!  Third-Party Controls  DEMO: Create and use a user control

33. Enriching the Client Experience

34. ASP.NET AJAX? Nope!

35. Filling the Gap  Roll your own  Popular Frameworks  jQuery  prototype  JavaScriptMVC  Rico  script.aculo.us  ASP.NET AJAX (client library)  DEMO: MVC & ASP.NET AJAX
