  6. 6. I love ASPX! Seriously?? • Let’s do a demo! • Make a ASP.NET Web form solution • ASPX vs the real web page
  7. 7. 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
  8. 8. 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
  9. 9. MVC pattern
  10. 10. How it serves Requests? • Controller contains Action methods • Every Action method can return a View (and raw json and other formats)
  11. 11. 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
  12. 12. 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
  13. 13. View • Strongly typed! • How we intermingled C# and HTML? • Razor view engine – converts C# into actual HMTL @ Server
  14. 14. Demo Time!!!
  15. 15. 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
  16. 16. 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
  17. 17. Partial Views Quick Demo
  18. 18. Layout and _ViewStart • Layout views are “master pages” • _ViewStart.cshtml – Code inside this view executes before every view renders
