ASP.Net Tutorial for Beginners with Examples using C#

This article gives you a basic introduction to asp.net framework. I will explain why people choose ASP.Net over classic ASP and what is the underlying technology behind ASP.Net.

Looking Back: Active Server Pages (Classic ASP) | Microsoft Active Server Pages (ASP) is a server-side scripting technology.

Problems with Classic ASP

  • Interpreted and Loosely-typed code
  • Mixes layout (HTML) and logic (scripting code)
  • Limited development & debugging tools
  • No real state management
  • Obscure Configuration Settings

Introducing ASP.NET

ASP.NET is a technology for building powerful, static and dynamic web applications or web content management system, ASP.NET is a compiled dot net based environment. It provides the easy way to build, deploy & run the web application on any browser.

Advantages of ASP Dot Net

  • It makes development simple and easy to maintain with event-driven and server-side programming model.
  • The asp.net source code is executed on the server. The source code is compiled the first time the page is requested. The server serves the compiled version of the page for use next time the page is requested.
  • Asp.Net provides validations controls and data controls.
  • Separation of Code from HTML
  • Support for compiled languages
  • Use services provided by the .NET Framework
  • Graphical Development Environment
  • State management
  • XML-Based Configuration Files

ASP.NET Overview

  • ASP.NET provides services to allow the creation, deployment, and execution of Web Applications and Web Services
  • Like ASP, ASP.NET is a server-side technology
  • Web Applications are built using Web Forms. ASP.NET comes with built-in Web Forms controls, which are responsible for generating the user interface. They mirror typical HTML widgets like text boxes or buttons. If these controls do not fit your needs, you are free to create your own user controls.
  • Web Forms are designed to make building web-based applications as easy as building Visual Basic applications

ASP.Net Page Life Cycle Events with Example

It includes initialization, instantiating controls, restoring and maintaining state, running event handler code, and rendering. Keep in mind word “SILVER” in your memory, which is defined as :

S = Start, I = Initialization, L = Load, V = Validate, E = Event Handlers, R = Render

  • Page Request
