The ASP.Net Page Life Cycle and View State Illustrated

Wed, 09 Jul 2008 21:11:00 GMT

The ASP.NET Page Life Cycle

Each time a request arrives at a Web server for an ASP.NET Web page, the first thing the Web server does is hand off the request to the ASP.NET engine. The ASP.NET engine then takes the request through a pipeline composed of numerous stages, which includes verifying file access rights for the ASP.NET Web page, resurrecting the user's session state, and so on. At the end of the pipeline, a class corresponding to the requested ASP.NET Web page is instantiated and the ProcessRequest() method is invoked (see Figure 1).

Figure 1. ASP.NET Page Handling

This life cycle of the ASP.NET page starts with a call to the ProcessRequest() method. This method begins by initializing the page's control hierarchy. Next, the page and its server controls proceed lock-step through various phases that are essential to executing an ASP.NET Web page. These steps include managing view state, handling postback events, and rendering the page's HTML markup. Figure 2 provides a graphical representation of the ASP.NET page life cycle. The life cycle ends by handing off the Web page's HTML markup to the Web server, which sends it back to the client that requested the page.

Note A detailed discussion of the steps leading up to the ASP.NET page life cycle is beyond the scope of this article. For more information read Michele Leroux-Bustamante's Inside IIS & ASP.NET. For a more detailed look at HTTP handlers, which are the endpoints of the ASP.NET pipeline, check out my previous article on HTTP Handlers.

What is important to realize is that each and every time an ASP.NET Web page is requested it goes through these same life cycle stages (shown in Figure 2).

Figure 2. Events in the Page Life Cycle

Figure 4 illustrates the sequence of events that transpire, highlighting why the change to the Label's Text property needs to be stored in the view state.

What is Windows Communication Foundation? Windows Communication Foundation is Microsoft's unified programming model for building service-oriented applications with managed code. It extends the .NET Framework to enable developers to build secure and reliable transacted Web services that integrate across platforms and interoperate with existing investments. Windows Communication Foundation combines and extends the capabilities of existing Microsoft distributed systems technologies, including Enterprise Services, System.Messaging, Microsoft .NET Remoting, ASMX, and WSE to deliver a unified development experience across multiple axes, including distance (cross-process, cross-machine, cross-subnet, cross-intranet, cross-Internet), topologies (farms, fire-walled, content-routed, dynamic), hosts (ASP.NET, EXE, Windows Presentation Foundation, Windows Forms, NT Service, COM+), protocols (TCP, HTTP, cross-process, custom), and security models (SAML, Kerberos, X509, username/password, custom).

Team Foundation Server includes a set of Web services and databases. These services and databases are installed and configured separately on the Team Foundation application tier, data tier, and client tier.

How Can I disable Theme for a Control in ASP.Net?

Thu, 14 Feb 2008 00:08:00 GMT

You can configure a page or control to ignore themes. Themes override local settings for page and control appearance by default. Disabling this behavior is useful when a control or page already has a predefined look that you do not want the theme to override.

Using JavaScript in ASP.NET

Mon, 11 Feb 2008 23:21:00 GMT

Web developers have been working around the limitations of the browser for a long time by using a combination of server-side processing and client-side processing. Working logic and application processes on the client-side allows browser based applications to seem more responsive and to have more "snappiness" to them. For client-side development in the past, most developers turned to JavaScript and intermingled this programming language into their classic Microsoft® Active Server Pages along with their server-side Microsoft Visual Basic® Scripting Edition or Microsoft JScript® code. Now with Microsoft ASP.NET and the new models that it provides, Web developers often wonder how to properly work with their JavaScript functions in their ASP.NET pages. This article will take a look at some of the ways past JavaScript functions can now be used. There is more than one way to accomplish this task and this article will take a look at many different possibilities. This article will also take a look at some of the m
