Asp.net and .Net Framework ppt presentation
.NET is a framework developed by Microsoft that enables the creation of dynamic web applications using ASP.NET, which was first released in 2002. It features a compilation model allowing multiple versions of the framework to exist concurrently and supports various programming languages and web technologies. Key elements include web forms for dynamic content, validation mechanisms, and web services for data exchange.

- 17. ASP.NET • Asp.net isan 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
- 18. ASP Architecture IIS (asp.net_isapi.dll) (InternetInformation Server) Client Server Request: http://www.msn.com/default.aspx Response: <html>…</html> Network HTTP TCP/IP PC/Mac/Unix + Browser (IE, FireFox)
- 19. Web Forms • WebForms 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 .
- 20. Codebehind model • Microsoftrecommends 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.
- 21. Directives • A directiveis 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

- 23. VALIDATIONS Validations is aProcess of checking the user input forVarious checks before the form is submitted to the server. • CompareValidator • Required FieldValidator • RangeValidations • Validation Summary • Regular ExpressionValidator

- 25. WEB SERVICES • Webservices can be defined as a piece of code that runs on a web server and provides data to the requesting clients. 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. 6) Web services are normally in the form of classes and public methods. SOAP : SOAP means Simple Object Access Protocol which is used to invoke a web service hosted on the network
