I love ASPX! Seriously??

• Let’s do a demo!

• Make a ASP.NET Web form solution

• ASPX vs the real web page

ASP.NET Web forms• Abstract away the web!

• Focus on Server side processing

• Code behind and Server control

• Table => GridView

• Click events replaces “Post” operation

• Originally design from/for late 90s technologies

• Now web standards have strengthened

• Client side programming on the rise

System.Web

ASP.NET MVC – Design goals• Does not replace web forms! An alternative…• Still runs on ASP.NET• All awesomeness still available – modules, handlers, master pages, session

state, Caching, auth.

• Embrace the web• No illusions of state – No Page lifecycle• Clean HTML and clean URLs

• Separation of concerns!!! – You will love it!• Testable – Big win

MVC pattern

How it serves Requests?• Controller contains Action

methods• Every Action method can return

a View (and raw json and other formats)

MVC Routing

• Routing is the magic component!

• Directs incoming requests to an MVC Controller

• Defines routes during application startup

• Map URLs to control action with parameters

• System.Web.Routing Binary – Part of ASP.NET

Controller

• Heart of MVC

• Contains public method called as Actions

• Method invokes by ASP.NET once routing decides the proper path

• Returns an ActionResult – Tells the framework what to do next

View

• Strongly typed!

• How we intermingled C# and HTML?

• Razor view engine – converts C# into actual HMTL @ Server

We will see in demo!

Demo Time!!!

Model

• Contains business/domain logic

• Doesn’t bother about presentation of Data

• May (or may not) contains database access logic

• Server side validation for Business logic

Demo: Creating a model from POCO classes

HTML Helper & ViewBag

• Quick, clean and short way

• Helpers available for frequently used html elements

• ViewBag contains Key-Value dictionary pairs.

• Can be passed from Action to View

Partial Views

Quick Demo

Layout and _ViewStart

• Layout views are “master pages”• _ViewStart.cshtml – Code inside this view executes before every view

renders
