ASP.NET MVC 1.0 provides a new Model-View-Controller (MVC) framework on top of the existing ASP.NET 3.5 runtime[1].We will build a complete MVC app from ground zero and will explore the underlying MVC details. We will compare ASP.NET web application with MVC app . Aim of this presentation is to establish a solid understanding of this new application model.

  1. 1. MVC for ASP.NET Developers Abhijit Gadkari Enterprise Architect Yet Other WebFramework!
  2. 2. Million $ Question? “Who here is attending this talk because you are concerned that ASP.NET MVC is going to throw out all of your existing knowledge on Web Forms and require you to learn new technology?” From Chapter 2 of the Professional ASP.NET MVC
  3. 3. Please Note: Release of ASP.NET MVC does not mean the death of Web Forms. This just isn't true. ASP.NET MVC is not ASP.NET Web Forms 4.0. It's an alternative to Web Forms, and it's a fully supported part of the [.NET] framework. Professional ASP.NET MVC 1.0 by Scott Guthrie et al. [page 171]

  6. 6. Model View Controller (MVC) is one of the most quoted (and most misquoted) pattern around. It started as a framework developed By Trygve Reenskaug for the Smalltalk platform in the late 1970s. Since then it has played an influential role in most UI frameworks and the thinking about UI design. - from Patterns of Enterprise Application Architecture by Martin Fowler Page 330 View Controller Model Splits user interface interaction into three distinct roles.
  7. 7. What is a Model View Controller (MVC) Framework? MVC is a framework methodology that divides an application's implementation into three component roles: models, views, and controllers. "Models" in a MVC based application are the components of the application that are responsible for maintaining state. Often this state is persisted inside a database (for example: we might have a Product class that is used to represent order data from the Products table inside SQL). "Views" in a MVC based application are the components responsible for displaying the application's user interface. Typically this UI is created off of the model data (for example: we might create an Product "Edit" view that surfaces textboxes, dropdowns and checkboxes based on the current state of a Product object). "Controllers" in a MVC based application are the components responsible for handling end user interaction, manipulating the model, and ultimately choosing a view to render to display UI. In a MVC application the view is only about displaying information - it is the controller that handles and responds to user input and interaction.
  8. 8. One of the benefits of using a MVC methodology is that it helps enforce a clean separation of concerns between the models, views and controllers within an application. Maintaining a clean separation of concerns makes the testing of applications much easier, since the contract between different application components are more clearly defined and articulated.

  9. 9. My First MVC Application... MVC is built on top of ASP.NET
  10. 10. 3 Controllers 4 Models 5. Scripts 2 Views 1 px Convention over Configuration!
  11. 11. MVC with real Model...
  12. 12. Summary MVC framework is not an alternative to the existing web form Technology. Use Web Forms on projects where you use third party server controls, web parts and dynamic data Going forward MS will support MVC as well as Web Forms MVC can be added to the existing ASP.NET web form application ASP.NET MVC ASP.NET Web Forms No Server Controls Based on the standard server control model No Postbacks and ViewState – Postbacks and ViewState is an View will talk to the controller integral part of this framework Controller is the glue that binds Codebehind file is a glue that a view with the model binds a view with the model Doesn't hide HTML & HTTP Hides HTML and HTTP
