What is ASP.NET?

Successor of ASP (Active Server Pages)

ASP.NET is not a scripting language or a programming language

“Programming framework built on the common language runtime that can be used on a server to build powerful web applications” - Microsoft


What do we need?

Web Server IIS 5 / IIS 6 (Internet Information

Services) Apache (using mod_mono from MONO

project) XSP standalone web server, also from

MONO

.NET Framework Text editor or IDE


Pros and Cons

Better performance – Compiled code

.NET Framework class library Multi language support Simplicity Separation of logic and

presentation


What’s new in ASP.NET 2.0 New Server Controls Master Pages Themes and Skins 64-bit Support Caching Improvements Admin and Management Tools …


ASP.NET Architecture

Web clients (browsers) communicate with IIS

IIS communicates with ASP.NET engine

The ASP.NET engine communicates with the .NET Framework


ASP.NET Page Processing Browser makes a HTTP request The web server (IIS) receives the request IIS examines the request and routes it to

the appropriate engine ASP.NET engine generates output and

sends it back to the browser


IIS Installation and Configuration Demo


Recap

What is ASP.NET What do we need to start Pros and Cons What’s new in ASP.NET 2.0 Architecture Syntax Server Controls Code-behind Validation Controls

Basic Syntax

ASP-like: <% … %><% for (int i=3; i<7; i++) { %>

">Welcome to ASP.NET 

<% } %>

Welcome to ASP.NET


Basic Syntax Demo

Code-behind

Not present in old ASP Separates logic from

presentation<%@ page language="C#" CodeFile="CodeBehind_cs.aspx.cs" Inherits="CodeBehind_cs_aspx" %>

using System;

public class CodeBehind_cs_aspx : System.Web.UI.Page {

protected void Button1_Click(object sender, EventArgs e)

{

Label1.Text = "Hello " + TextBox1.Text;

}

}


Code-behind Demo


Server Controls

Look just like HTML form controls Retain their values after

postback Control’s Attributes can be

Accessed on the Server Available to use from the .NET

class library Need two attributes:

ID=“name_of_control” runat=“server”


Server Controls Demo


Validation Controls

New in ASP.NET Perform form input validation Several types:

Required Field Validator Range Validator Compare Validator Regular Expression Validator Custom Validator Validation Summary


Validation Controls Demo
