REVIEWThe way of ASP.NET MVC

The Downside of ASP.NET

• Very complex page pipeline engine• Difficult to maintain • Impossible to test

– Difficulty partially arises from simulating Context, Request, Response, and Session objects.

• The cryptic control ids and sensitivities of ViewState

• Overly mix business and presentation logic• Event-driven model

Innovation!

ASP.NET MVC IS……

• New ASP.NET application development style– Another is“ASP.NET Web Form”– Fill the gaps of ASP.NET Web Form

• New choice• Full control over URLs• Full control over HTML• Easier to test (TDD) • Flexible, extendable, easily replaced

ASP.NET MVC IS NOT……

• The substitute of 3-tier structure• ASP.NET Web Form’s substitute • ASP.NET Web Form promotion version– ASP.NET Web Form 4.0

• Fit RAD• Fit every project• Fit everyone

Different Between with Web Form

Classic Web Form ASP.NET MVC

Postback REST, HTML Post

Code behind Separate controller

Single form Multiple forms

Server controls HTML Helpers

Page and control lifecycle Controller

UNDERSTANDING ASP.NET MVCUnderstanding Models, Views, and Controllers

ASP.NET Routing

• URL Patterns• Setting Default Values for URL Parameters• Adding Constraints to Routes• Scenarios When Routing Is Not Applied• How URLs Are Matched to Routes• Accessing URL Parameters in a Routed Page• ASP.NET Routing and Security• ASP.NET Routing versus URL Rewriting

Working with Models

• What’s Model

• Validation

Controllers & Action

• Receiving input– QueryString, Request.Form, FormCollection, Custome(IModelBinding)

• Filter• Aysnc action• Producing output

– Action Result, View Data, View Model

• How defines– End with the word Controller– Inherit from System.Web.Mvc.Controller (or implement Icontroller– Contain public methods that return ActionResult

Filtering Action Methods

Working with Views

• View Engine• View Page• View Data• View Helper• Form Post• Using MasterPage• Order

CUSTOMIZING AND EXTENDINGMVC Custom and Extensions

Customizing & Extending

• Extending URL Routing• Customer ControllerFactory• Extending Controller & Action• Custom View Engine• T4 Template

BEST PRACTICESTruth in Practice

Best Practices

Securing MVC applications Dependency Injection of Controllers Using RESTful Architecture Handling errors in MVC applications Unit Test & MVC Mock Helpers Using AJAX in ASP.NET MVC applications Improving ASP.NET MVC application performance Localizing ASP.NET MVC Validation Deploying MVC applications

MVC 2.0 NEW FEATURESAreas, Async Controllers Support, Scaffold …

• New Strongly Typed HTML Helpers• Enhanced Model Validation support across both

server and client• Auto-Scaffold UI Helpers with Template

Customization• Support for splitting up large applications into

“Areas”• Asynchronous Controllers support that enables

long running tasks in parallel• Support for rendering sub-sections of a page/site

using Html.RenderAction• Lots of new helper functions, utilities, and API

enhancements• Improved Visual Studio tooling support

Areas

• Introduction– Organizing our projects hierarchically into

folders and namespaces

• Building a portable area• Embedding Views• Distributing a portable area

Async Controllers Support

• Change the way of request handling• Decide whether the action is async or

not• Execute an action• ModelBinder support• Limitations and drawbacks
