ASP.NET
• Asp.net is an open-source server-sideWeb application framework designed for Web
development to produce dynamic Web pages. It was developed by Microsoft to allow
programmers to build dynamic web sites, web applications and web services.
• first released in January 2002 with version 1.0 of the .NET Framework.
• 1)Web forms
2)MVC

Web Forms
• Web Forms are pages that users request using their browser.These pages can be written using a
combination of HTML, client-script, server controls, and server code. An ASP.NET Web Forms
page presents information to the user in any browser or client device.
• The ASP.NET Web Form is separated into two logical areas:
• The template (designing code).
• A collection of code behind the Web Form .

Codebehind model
• Microsoft recommends dealing with dynamic program code by using the codebehind model, which places
this code in a separate file or in a specially designated script tag.
• Codebehind files typically have names like MyPage.aspx.cs while the page file is MyPage.aspx.

Directives
• A directive is a special instruction on how ASP.NET should process the page.
• The Most Common directive is <%@ Page %> which can specify many attributes used by the A
SP.NET page parser and compiler.
• Example:
<%@ Page Language="C#" AutoEventWireup=“True" CodeFile="Default.aspx.cs"
Inherits="Default" %>
• When AutoEventWireup is true, ASP.NET automatically treats a method of name Page_eventName as
an event handler

WEB SERVER CONTROLS
• TextBox
• Button
• Radio Button/Radio Button List
• CheckBox/ CheckBox List
• HyperLink/Link Button
• Fileupload Control

VALIDATIONS

the form is submitted to the server.
• CompareValidator
• Required FieldValidator
• RangeValidations
• Validation Summary

WEB SERVICES

Characteristic's ofWeb Services :
1) It’s a logic and does not contain UI.
2) Web services are hosted on webserver.
3) Web services transfer data in the form of XML/JSON
4) They are Platform Independent
5) Web services interact with the Database.
