Ajax-enabled components that use the Periodic Refresh pattern periodically poll the server for changes. This article develops an Ajax-enabled custom control named AjaxNotifier that will show you how to use the Periodic Refresh pattern to develop your own Ajax-enabled controls. AjaxNotifier is an Ajax-enabled control that periodically polls the server for the latest posted notification and displays the notification in a pop-up dialog, shown in Figure 1. As this figure shows, the pop-up dialog exp... |

When Microsoft added the ActiveX XMLHTTP object to Internet Explorer's implementation of JavaScript, the company planted the seed for the revolution in Web applications known as Asynchronous JavaScript and XML, or AJAX. Today, Firefox, Safari, Opera, and other browsers all support what is now known as XMLHttpRequest, making possible sites such as colr.org, backpackit.com, and maps.google.com. These and other sites feature applications that act and feel like other desktop applications—even though... |

Thankfully, most existing Web applications will work reasonably well on the iPhone with no modification necessary. However, if you want to create a first class iPhone application, you should study the iPhone development tips detailed here. When Apple’s first iPhone was originally released to the public, Steve Jobs announced that its development platform would be “Web 2.0.” The iPhone’s integrated Safari Web browser is clearly the most sophisticated Web browser ever built into a handheld device. ... |

It has been a while since I posted the InPlaceEditing sample which features an Atlas extender control and script behavior. The goal was to show how the Atlas platform makes it really possible to build and incorporate rich Web experiences. This post will focus on building the script behavior. Rather than covering things line-by-line, I'll touch upon the key points. I'll cover the extender control in the next post. One fundamental aspect of Atlas both in terms of the technology and in terms of pra... |

One of the most important challenges web application developers face is the requirement for a fast and responsive user interface. AJAX was primary designed and developed with the intent of providing a fast and responsive user interface to address these challenges. According to Enrich Peterson, "AJAX-enabled pages provide a slick, responsive user experience, making web-based applications function more like desktop-based ones".... |

When developing an ASP.NET web site that uses an AJAX functionality, sooner or later, you realise that the process of developing AJAX based web controls starts getting repetitive: you end up writing the same JavaScript for creating and handling the XmlHttpRequests on the client side as well as on the server side. At this point, you probably already have an external JavaScript file that is referenced in your master page, and then you realise it all begins to evolve into some blown up JavaScript m... |

AJAX (Asynchronous JavaScript and XML) has become so popular, thanks to Google Suggest. AJAX has opened the possibility to make more responsive and interactive web applications, bringing them closer to Windows form applications. Web developers are the bunch of guys who were happy at first. They have a new toy, which is composed of old toys they have neglected so far, and now they can make cool things with the toy. On the other hand, after getting their free account in GMail, end users demand mor... |

In this tutorial we’ll examine the concept of script controls, how they differ from extender controls and how we can build a base abstract class which implements client state and dynamic loading of embedded CSS files. In my previous article titled ASP.NET 3.5 AJAX Extender Controls we examined AJAX extender controls and how they can be used to extend the functionality of a standard ASP.NET control, however, there is another side to the coin, that is, custom controls with AJAX script functionalit... |

The goal of the blog entry is simple: I want to understand everything happening under the covers when you take advantage of ASP.NET AJAX inheritance. The JavaScript code in Listing 1 defines two objects named BaseControl and TreeViewControl. These objects might represent user interface controls that are displayed in a web page. The TreeViewControl inherits from the BaseControl object.... |

Microsoft's ASP.NET AJAX Control Toolkit is as open source as Microsoft gets, as Scott Guthrie noted in his blog entry announcing the toolkit. The ASP.NET AJAX group will set up a source control repository where developers can report bugs or contribute their own controls, said Guthrie, who leads that development group. There will also be regular binary drops. "This first release is just the beginning," Guthrie wrote. Microsoft's goal, he added, is to have the ASP.NET AJAX Control Toolkit contain... |

The majority of development experts advocate an incremental approach to implementing Ajax functionality in Web applications. Since the early days of building Visual Studio 2005, Microsoft has offered frequent versions of its key software tools, giving developers a chance to play around with the technology and send feedback to Redmond. These two concepts are coming together with Microsoft's Atlas Control Toolkit. Atlas, Microsoft's tool for incorporating Ajax into ASP.NET applications, debuted at... |

Visual Studio 2008 should be released around the time you read this article. Visual Studio 2008 includes the .NET Framework version 3.5, which includes ASP.NET version 3.5. ASP.NET 3.5 includes ASP.NET AJAX (codenamed Atlas), which was previously available as a separate downloadable add-on to the preceding version of ASP.NET (version 2.0.) If you’ve been using ASP.NET 2.0 AJAX, then you’re aware it required a significant number of additions to the web.config file. These web.config settings are n... |

When using ASP.NET AJAX Extensions to transition your site to an AJAX experience, there are two main programming models to choose from: partial rendering and script services. In last month's column, I discussed partial rendering from a primarily architectural perspective. Simply put, with partial rendering, you don't need to change the underlying architecture of an ASP.NET application—it's an easy route to implementing some of the best elements of AJAX, such as no-flicker updates to pages on you... |

The last installment of Facebook Developer tutorials explains how to reduce bandwidth by replacing FBML fb:dialog tags with AJAX-enabled FBJS Dialog objects. However, while the tutorial demonstrates how to reduce response lengths, the code did not account for one major issue. Because the dialog does not appear on-screen until the AJAX receives a response, and because the AJAX requesting the dialog’s contents could potentially have a slow or marginal response time, the end user is left wondering ... |

The toolkit is a shared-source community project consisting of samples and components that make it easier to work with AJAX-enabled controls and extenders. The ASP.NET AJAX Control Toolkit provides both ready-to-run samples and a powerful SDK to simplify creating custom ASP.NET AJAX controls and extenders. It uses ASP.NET AJAX Extensions, which must be installed to utilise the toolkit.... |

In part 1 we examined several extenders in the AJAX Control Toolkit that are useful for enhancing the standard ASP.NET Panel control. Our exploration of the AJAX Control Toolkit now continues as we examine several more extenders that can bring new life to the boring old ASP.NET Panel control; we continue the journey by examining the AlwaysVisibleControl and ResizableControl extenders and the Accordion control.... |
