This document provides an overview of the MVC pattern and its components. MVC separates an application's source code into three parts - the Model, View, and Controller. The Model handles the application's data logic and rules. The View displays the data to the user. The Controller interprets user input and calls the Model and View to perform actions. The document discusses how MVC is used in various programming languages and frameworks like ASP.NET MVC, and outlines the typical project structure and workflow using MVC.

- 2. INDEX • 1. MVC Pattern Overview • 2. Language Applied • 3. Components • 4. Workflow • 5. Project Structure • 6. Major Functions • 7. Main difference between ASP.Net Web Form and ASP.Net MVC • 8. Advantages • 9. Disadvantages
- 3. MVC Overview Review 3 layers pattern Presentation Business access Data access Data objects Data validation, handle data Data access Data presentation Data validation
- 4. MVC Overview • MVC stands for Model – View – Controller • MVC Pattern is a software architecture and design pattern used in software engineering. • MVC Framework is an open source web application framework that implemented the MVC Pattern. • Separate source code into 3 components. Each components has a specific task and connect to other components.
- 5. MVC Overview .Net Framework ASP. Net Core Engine ASP.Net Framework Stack ASP.Net Web Forms ASP.Net MVC
- 6. Language applied • Ruby – Ruby on Rails, PureMVC. • .NET - Sprint.Net, MonoRail, ASP.Net MVC. • Java - Swing, Struts, Spring. • Python - Django, PureMVC. • Object-C - Cocoa, Cocoa touch.
- 8. Components of MVC View • Handle the display of data and controls. • Include HTML tabs to show data from Model and receive input from user • The View are built from data of the Model. • Validate input from the client via JavaScript/Jquery. • Send user actions to the Controller.
- 9. Components of MVC Controller • Contain Action (Method) • Navigate data • Read user action from the View. • Execute query to the Model. • Decide what should be returned to the View.
- 10. Components of MVC Model • Determine what model the Controller need. • Business/Domain logic layer • Receive data from database. • Calculate, handle data and logic of data. • Store objects describe data as Classes. • Include methods of processing and accessing database. • Check the validity of data (Model Validation).
- 11. Workflow Controller Model View User action Notify changes Select View Change state
- 12. Project Structure Controller classes Script files Jquery/AJAX Model classes View files ASPX/CSHTML(Razor View)
- 13. Major functions • Razor View Engine • Validation • Routing
- 14. Razor View Engine • Another way of showing data in the View. • Appear in ASP.Net MVC 3 framework and later. • Decrease markup code. • Provide a compact way to mix code with markup. • Use the @ character at first in syntax.
- 15. Razor View Engine ASPX View
- 16. Razor View Engine Razor View
- 17. Validation • Validation with “Validation Attribute” - Server • Validation with Jquery/Unobtrusive – Client.
- 18. Validation Attribute [Required] [MaxLength] [Range] [Compare] [DataType] [RegularExpression] Extensible • A value must be provided • Value must have a specific length • Value must be in a specific range [a-b] • Value must be equal another property • Value must satisfy a type of data • Value must satisfy a regular expression • Custom model validation
- 21. Jquery/Unobtrusive Validation Add Jquery library
- 22. Jquery/Unobtrusive Validation HTML code generated
- 23. Routing • History /store/editproduct.aspx?id=50 • Call Controller and Action through parameters base on a route table …/product/editproduct/01 …/editproduct/01 Action Parameter valueController
- 26. Main difference between ASP.Net Web Form and ASP.Net MVC Framework ASP.NET Web Forms ASP.NET MVC Every page(abcd.aspx) has its own controller (abcd.cs). Common controller can be used for many view pages have request. UI and logic code are coupled tightly. Code is clean because of the seperation of this pattern. View page size is big. View page size is small. One View engine ASPX Support for Multiple View Engines (Razor, Spark, Ndjango, ..)
- 27. Advantage • - Professionalism in programming • - Easy to read and understand source code in big project. • - Easy to develop, improve and maintain program.
- 28. Disadvantage • In small project: • Waste time in building source code. • Cause complexity in transfering data between components.
