The view engines used in the ASP.NET MVC 3 and MVC 4 frameworks are Razor and the Web Forms. [ 29 ] [ 30 ] Both view engines are part of the MVC 3 framework. By default, the view engine in the MVC framework uses Razor .cshtml and .vbhtml , or Web Forms .aspx pages to design the layout of the user interface pages onto which the data is composed.
Code-behind files typically have names like "MyPage.aspx.cs" or "MyPage.aspx.vb" while the page file is MyPage.aspx (same filename as the page file (ASPX), but with the final extension denoting the page language). This practice is automatic in Visual Studio and other IDEs, though the user can change the code-behind page name. Also, in the web ...
Diagram of interactions in MVC's Smalltalk-80 interpretation. Model–view–controller (MVC) is a software design pattern [1] commonly used for developing user interfaces that divides the related program logic into three interconnected elements.
For example, if an Account object has a PhoneNumber property, and that property is assigned a phone number with alphabetic characters, the Account object's IsValid property will become false (making it impossible to save to the database) and then a new BrokenRule object will be created and assigned to the Account's Broken Rules collection. The ...
For example, dependency injection can be used to externalize a system's configuration details into configuration files, allowing the system to be reconfigured without recompilation. Separate configurations can be written for different situations that require different implementations of components.
[3] [4] [12] [clarification needed] It uses the binder, view model, and any business layers' data-checking features to validate incoming data. The result is that the model and framework drive as much of the operations as possible, eliminating or minimizing application logic which directly manipulates the view (e.g., code-behind).
The adapter [2] design pattern is one of the twenty-three well-known Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse. The adapter design pattern solves problems like: [3]
