BEGINNING ASP NET 4 IN C

❑ Body tag’s onload() event — The onload() event may not properly fire. To create this same type of functionality, the command <application load=”yourFunction”/> can be added to the XML/script section of your page.
❑ Timing issues — There will most likely be other timing related problems,[r]

Handling the Result of Asynchronous Server-Side Call on the Client
Now that the asynchronous call has been executed, the server-side processing has been performed, and the results have been sent back to the client browser, you must have a way of receiving and processing those results. This repres[r]

SAX processing is based on asynchronous events. In this model, as the XML document is read and parsed, events are fired as set up by the program. This is believed to result in faster XML processing than the DOM, because of a much smaller memory footprint compared to using a fully loade[r]

HTTP Handlers
A more typical approach to handling these requests is to use an HTTP handler. A handler has the ability to
respond to requests with more direct control over the response data. Essentially, an HTTP handler exists very early in the ASP.NET processing pipeline and[r]

Here you can see that the exception message has been displayed, in addition to the result of the
GetCallbackResult method. Both of the messages have been aggregated together, but separated by a pipe ( | ) character. What is happening is that the asynchronous client script framework is sti[r]

Digging into response.value
In the first example, you received a string in the response.value property. This was the string name of the image LeftArrow or RightArrow that you used to set the image source to change the image from right to left. Strings can be very helpful and ar[r]

property collection is specific to Internet Explorer 4 and above.
❑ DOM Level 2 — This level combines both DOM Levels 0 and 1, provides methods to access and manipulate style sheet elements, and provides further access to page elements relating to XML. There are other features that contribu[r]

In the preceding example, the prototype contains two properties ( isSecret and isActive , which are assigned initial values), a function named checkIfActive() , and a parameterized constructor. Contrast this to the previous example where a generic object is initially constructed, and then p[r]

JavaScript and the Document Object Model go hand in hand when dealing with dynamic web applica- tions. JavaScript provides the engine, while the DOM provides the vehicle. Many web application developers exist without knowing why something works in one particular browser and often reso[r]

Just a reminder of what was stressed in Chapter 2 — typically, for the sake of consistency and clarity, most developers will terminate each line with a semicolon regardless of whether there are multiple state- ments per line or not. This is the recommended approach for all JavaScript develo[r]

Language Enhancements
JavaScript has been around as a language since the early betas of the Netscape Navigator 2.0 web browser appeared in late 1995 to early 1996. Since then, there have been numerous enhancements to the JavaScript language. The latest version of the language is version 1.6[r]

This example demonstrates how you can use Anthem.NET to call sever-side code without requiring the use of a panel or custom controls. Anthem.NET implements this feature in a similar fashion to the Ajax.NET framework, but instead of creating a proxy object for each page th[r]

Summar y
You have had an opportunity to review three client-side Ajax frameworks and work with three server- side Ajax frameworks that approach problems in development in different ways.
On the client side, Sarissa, HTMLHttpRequest, and MochiKit provide a lightweight way of abstra[r]

Like many other Ajax-style libraries and frameworks, this library provides a layer of abstraction around the XMLHttpRequest object and shields the developer from having to know any intricate details about coding against that specific object. The purpose of this library is somewhat different and m[r]

05.</system.web>
This Web.Config modification tells ASP.NET that all requests that come in for the AjaxPro directory with ASHX file extensions should be processed by the Ajax.NET Pro library. What this allows you to do is have a page request, with a page name, th[r]

Architectural Distinctions
Every software architect tries to solve the same problems using a different approach. An Ajax-enabled page will not only use the XmlHttpRequest object but will also need to alter the rendered page to update the user interface. Each library highlighted in this sec[r]

For this chapter, we have created a new Visual Studio project called SportsStore using the ASP.NET Empty Web Application template once again. We’ll start off by setting up a data model and a database and then adding in the other features we require.

object implement a security policy called the “same origin” policy. This means that a request issued using an XMLHttpRequest object must be to a server of the same origin from which it was loaded.
For example, if a web page were loaded from www.yourserver.com/somepage .aspx , then all requests i[r]
