The document outlines the MVC (Model-View-Controller) design pattern introduced by Trygve Reenskaug in 1979, emphasizing separation of concerns and single responsibility principles. It details the components of MVC, including how to handle user requests, data binding, and view rendering, as well as features like unit testing, flexible routing, and integration with AJAX. Additionally, it covers ASP.NET MVC's support for existing features, database interactions through Entity Framework, and various types of action results and filters for improved application performance and security.

Asp.net MVC training session
- 2. • A design Pattern (Methodology) • Invented by Smalltalk programmer (Trygve Reenskaug 1979). • Separation of Concerns / Single Responsibility Principle • More easily testable
- 3. M Model V View C Controller • Representation of domain data • Business Logic • Persistence mechanisms • User Interface • The representation of Model • An intermediary between Model and View • Application’s Brain (Handle user requests, bind Data, return views)
- 4. Ok C Controller M Model V View CreateInvoice (fact) Create invoice (data) fact = new Invoice () LatestInvoices () return view ("Last-Invoices", ListFact[]) ListFact[] HTML
- 5. • Part of ASP.NET • Not an upgrade or replacement for Web Forms ASP.NET Webforms MVC Webpages
- 6. • No server controls • No ViewState • No Code Behind • Full control over html • Unit Testing
- 7. • Separation of application tasks (No code Behind) • Flexibility and Extensibility • Friendly URLs (Routing) • Scalability and Performance • Supports existing ASP.NET features (Authentication, Membership, roles, output caching,…) • Natural integration with Ajax
- 9. • View Engines o Aspx o Razor • Layout • Partial View • Section • HtmlHelper, AjaxHelper
- 10. • ActionLink @Html.ActionLink(“Modifier", “Edit“, new {Id=3}) <a href="/Product/Edit/6">Modifier</a> • Form Elements (Form, TextBox, Hidden,….) @Html.TextBox(“Nom") <input id=" Nom " type="text" value="" name=" Nom ">
- 11. • DropDownList var db = new NorthwindDataContext(); IEnumerable<SelectListItem> items = db.Categories .Select(c => new SelectListItem { Value = c.CategoryID.ToString(), Text = c.CategoryName }); ViewBag.Categories = items; @Html.DropDownList("CategoryID", (IEnumerable<SelectListItem>) ViewBag.Categories)
- 12. • Ajax ActionLink @Ajax.ActionLink("Get Time", "GetTime", new AjaxOptions () { UpdateTargetId="divTorefresh", HttpMethod="GET" }) <a href="/Home/GetTime" data-ajax-update="#divTorefresh" data-ajax-mode="after" data-ajax-method="GET" data- ajax="true">Get Time</a>
- 14. • Action Results • Filters • Caching
- 15. • ViewResult • PartialViewResult • JsonResult • JavaScriptResult • ContentResult • FileResult • RedirectResult
- 16. • Authorization filters • Action filters • Result filters • Exception filters
- 17. [OutputCache(Duration=3600)] Public ActionResult GetListCountries() { // Logic to get countries list } [OutputCache(Duration=3600, VaryByParam = "countryId")] Public ActionResult GetListRegions(int countryId) { // Logic to get regions list }
- 19. • Annotation • Validation(Client Side & Server Side)
- 20. • Required • DisplayName • Range • DataType • StringLength
- 22. • Open source package manager for the .NET Framework • Provide the ability to produce and consume packages
- 24. • Bundling & Minification • Web Api • Template Mobile • Asynchronous • RealTime avec SignalR
- 25. Improve JavaScript and CSS files loading • Minimize the Number of requests (Bundle in one File) • Reduce the size of files (remove spaces, enters and comments) Fully customizable and extensible
- 29. • Entity Framework • Database First • Model First • Code First
- 30. • Object-relational mapping (ORM) Framework • Gives an automated mechanism for Data Access • Manipulate Data as Object • Reduce hard coded Query • Have inheritance relationships between entities • Performing basic CRUD(Create, Read, Update, Delete)
- 32. • Existing DataBase • Generate .Edmx From DataBase • Use ObjectContext & DBContext • Use T4 template (POCO)
- 33. • Empty Edmx Model • Design th DB Schema • Generate DataBase From Model
- 34. • Create Domain Models (Class) • Generate DataBase From Domain Models • Full Control Over Code • No Autogenerated code
- 36. • User Authentification • Authorization • Cross-site request forgery • Cross-site Scripting
- 37. • Forms Authentification • Cookies • Windows Authentification • Windows Session • Via IIS • OAuth • Facebook, google, Hotmail, twitter, etc.
- 38. • Role-based Authorization • [Authorize(Roles = "Admin, Super User")] • [Authorize(Users = "Betty, Johnny")]
- 39. • Malicious attack (Cross Domain) • Using Forms • Session hijacking
- 40. • Malicious attack Using Script Injection • Inject Code Inside Pages
- 42. • Design pattern • Removal of hard-coded dependencies • Giving an object its instance variables (Dynamically)
