Fundamentals of MVC

 Chapter 1 Fundamentals of MVC 

 

Microsoft's Web Development Platforms

Understanding the past can be a big help in appreciating the present.

 

1.ASP

asked for features such as improved code reuse,better separation of concerns,and easier application of object-oriented programming principles.

 

2. ASP.NET Web Forms

an abstraction from the underlying HTML,Js,and Css

 

3.ASP.NET MVC 

The Architecture encourages strict isolation between the individual parts of application.

Benefits:

    Development:Isolated componensts;

    Testability;

    Maintenance.

        

 

 

The MVC Architecture

The model repesents core business logic and data.

The view is responsible for transforming  a model or models into a visual representation.

The Controller is the coordinator between the view and the model.

 

The new in asp.net mvc 4

Async Controllers:just like node.js?

Display modes:different devices.

Bundling and minification:script and css combining and minification.

Web API:supply data to the different platform.

 

 

Convention over Config

 

Action Results

Content() :string

File():file e.g.,a pdf

HttpNotFound() :404

Javascript():js

Json()

PartialView() :without layout

Redirect():302

RedirectPermanent

View()

 

Action Filters

create own filters by extending the ActionFilterAttribute

 

Views

 

Code nuggets

    rendered inline. like this: @Html.ActionLink("Login", "Login")

Code blocks

    like this:@{}

 

Layouts

    layouts like this:

    

 

    content like this:

 

        

 

 

Partial Views

Displaying Data

      It  is the controller’s job to be the “traffic cop,” coordinating various parts of the system to         execute the application’s logic.

 

    ViewData , 

    TempData,

    ViewBag(dynamic) 

    View model(Strongly typed).

 

HTML and URL Helpers

 

HtmlHelper :helps you generate HTML markup

UrlHelper     :helps you generate URLs.

 

 

Models

    

 

 

Putting It All Together

 

As a recap, every ASP.NET MVC request requires at least three things: a route, a controller action, and a view (and, optionally, a model).

    

 

The Route

    

 

 

The Summary

 

ASP.NET MVC leverages the time-tested Model-View-Controller architecture pattern to provide a website development framework that encourages loosely coupled architecture and many other popular object-oriented programming patterns and practices.
