WEB DEVELOPMENT WITH ASP.NET

Web Development with ASP.NET

Web pages can be developed with ASP.NET technologies. It enables the development of web applications and services. The increasing use of the internet is one of the most important motivating factor for the development of ASP.NET platform. Today it is the fastest web development environment.

Programming in ASP.NET

Asp.net uses object oriented programming. The programming environment supports more than 25 .NET languages with built in support for VB.NET,C#,Jscript .NET. the .NET framework offers over 4500 software classes.

Development

Like all web pages Asp.Net web pages also reside in Web-accessible directories on the web server. A request from the browser retrieve the page for delivery to the client. The standard web pages simply transmitted back to the browser ,and it displayed immediately. ASP.NET pages first intercepted by the server, then ASP.NET processor scan the page for scripts, then this script run at the server then this newly generated information is added to the page appearing among the XHTML code and hard-coded text composing the original page. That is actually ASP.NET processor builds a new web page which combines the actual XHTML code with script generated information. Then this page is returned to the requested browser for display. So this web page is ready to display all the latest information available from the browser.

ASP.NET pages are composed of two sections, that is Script section and XHTML section. Script section is normally coded on the top of the page and it contains the server code to process input data and produces output information. The other section that is XHTML section displays the visual results of server processing in the browser.

As shown in above figure there is a direct interaction between two sections of the page. The XHTML page make a call to the script section of the page often supplies data for processing. Then the script section processes this and then generates the output. Then this output is placed in the XHTML section of the page and this output can be viewed when the page is returned to the user.
