4. What is MVC?
• The Model-View-Controller (MVC) architectural
pattern separates an application into three main
components:
1. Model
2. View
3. Controller.
The ASP.NET MVC framework provides an
alternative to the ASP.NET Web Forms pattern for
creating MVC-based Web applications.
5. Model
• Model objects are the parts of the application that
implement the logic for the applications data
domain.
• Often, model objects retrieve and store model state
in a database.
• In small applications, the model is often a conceptual
separation instead of a physical one.
6. • MVC model is basically a C# or VB.NET class
• A model is accessible by both controller and view
• A Controller can be used to pass data from
model to view
• A view can use model to display data in page.
7. View
• Views are the components that display the
application’s user interface (UI). Typically, this UI is
created from the model data.
• An example would be an edit view of a Products
table that displays text boxes, drop-down lists, and
check boxes based on the current state of a Products
object.
8. • View is an ASPX page without having a code behind
file
• All page specific HTML generation and formatting can
be done inside view
• One can use Inline code (server tags ) to develop
dynamic pages
• A request to view (ASPX page) can be made only
from a controller’s action method.
9. Controller
• Controllers are the components that handle user
interaction, work with the model, and ultimately
select a view to render that displays UI.
• In an MVC application, the view only displays
information; the controller handles and responds to
user input and interaction.
10. • Controller is basically a C# or VB.NET class which
inherits system.mvc.controller
• Controller is a heart of the entire MVC architecture
• Inside Controller’s class action methods can be
implemented which are responsible for responding
to browser OR calling views.
• Controller can access and use model class to pass
data to views
• Controller uses ViewData to pass any data to view
11. Test-Driven Development
• The MVC pattern makes it easier to test applications
than it is to test a Web Forms-based ASP.NET Web
application.
• Tests for Web Forms-based ASP.NET applications can
therefore be more difficult to implement than tests
in an MVC application
• Tests in a Web Forms-based ASP.NET application
require a Web server.
12. • The MVC framework decouples the components and
makes heavy use of interfaces, which makes it
possible to test individual components in isolation
from the rest of the framework.
• MVC application also promotes parallel
development.
• one developer can work on the view, a second
developer can work on the controller logic, and a
third developer can focus on the business logic in the
model.
13. Advantages of an MVC-Based Web
Application
• It makes it easier to manage complexity by dividing
an application into the model, the view, and the
controller.
• It does not use view state or server-based forms. This
makes the MVC framework ideal for developers who
want full control over the behavior of an application.
• It provides better support for test-driven
development (TDD)
14. • It works well for Web applications that are supported
by large teams of developers and Web designers who
need a high degree of control over the application
behavior
