Introduction to ASP.Net MVC

-
Image
Back to Home Model-View-Controller (MVC) is a software architecture pattern. Originally formulated in the late 1970s by Trygve Reenskaug as part of the Smalltalk, MVC architecture works on code reusability and separation of concerns. It was originally developed for desktop Then adapted for internet applications. The Model is the application object, the View is UI presentation, and the Controller defines the way the user reacts to user input from UI. MODEL: - Set of classes that describe the data we are working with - Rules for how the data can be changed and manipulated - May contain data validation rules - Often encapsulate data stored in a database as well as the code used to manipulate the data Most likely a Data Access Layer of some kind VIEW: - Defines how the application’s user interface (UI) will be displayed - Support master views (layouts)  - Support sub-views (partial views or controls) - Web: Template to dynamically generate HTML CONTR...

Applying Dynamic Themes to WebPage

-
Applying Dynamic Themes to Web Page (.aspx) in ASP.NET Themes and Skins. The themes and skins features in ASP.NET 2.0 allow for easy customization of your site's look-and-feel. You can define style information in a common location called a "theme", and apply that style information globally to pages or controls in your site. Like Master Pages, this improves the maintainability of your site and avoid unnecessary duplication of code for shared styles. protected void Page_PreInit( object sender, EventArgs e) { Page.Theme = Session[ "Theme" ] as string ?? "Theme1" ; } protected void Page_Load( object sender, EventArgs e) { } protected void Button1_Click( object sender, EventArgs e) { if (Session[ "Theme" ] != null ) { if (Session[ "Theme" ].ToString() == "Theme1" ) Session[ "Theme" ] = "Theme2" ; else Session[ "Theme" ] = "Theme1...

Abstract Class and An Interface

Differences between a Structure and Class

-
1. Clas s is Reference types and Structure is Value type.   2. Clas s supports an Inheritance where as Structure not.   3. Classes are usually used for large amounts of data, whereas Structure are usually used for smaller amount of data.   4. When we instantiate a class, memory will be allocated on the heap and when Structure gets initiated it gets memory on the stack. 5. Classes can have explicit parameter less constructors. But Structure doesn't have this. 6. Classes can be garbage collector because garbage collector works on heap memory . structures can not be garbage collector so no memory management.
