One key problem that AJAX addresses is improving Web application user interfaces. By reducing the need to constantly refresh the entire Web page, Atlas helps ensure that your Web application is always responsive to user actions. For example, suppose you're filling in a Web form to register for a free email account, or a free magazine and you are asked to select the country you are from. After you select the appropriate country, the entire page refreshes so that the application can now ask you sp...

If you are new to Ajax and would like to learn more, this article was written for you! Use it as a starting point to learn the basics of sending requests, receiving xml responses and using DHTML to update inputs on an HTML page. It's actually pretty easy, we'll show you how. This example contains only 4 files and will work on web servers that support asp or php. A recent version of either IE or Firefox is required to run the client-side HTML and Ajax JavaScript....

This morning, I had the chance to play around with another ASP.NET AJAX control: the CascadingDropDown control. Like the name implies, it's a nifty little AJAX-enabled control that dynamically enables and populates a DropDownList based on the value selected in a previous list. Kinda like the coding version of those old skool "Choose Your Own Adventure" books.You've seen this kind of thing in action plenty of times, I'm sure. Remember the last time you filled out a registration form that had ...

While browsing for answers through various ASP.NET blogs and forums I often come across certain topics which often repeat in one way or another.
This article is an exercise which answers some common GridView questions. Here I deal with:
1. Database connectivity
2. MS AjaxControlToolkit's Rating extender, which is put on every row alowing user rate each row in real time. In other words, as soon as the user rates the row, an asynchronous (AJAX) call to the server is made and the database ...

I started Ajaxion to learn Ajax and I finished by using it to enhance a web page in an old web application, under maintenance. Many thanks to my good colleague, Marius Francu, that supported the first "real world" usage of Ajaxion. The idea here is simple: there is an Ajaxion Javascript layer between the hosting page in the browser and the web server. The Ajaxion Javascript layer defines Ajaxion events enclosing Ajax calls to the web server. The web server runs some C# code (Java coming soon) to...

we've accomplished asynchronous updates, and we could stop there and feel pretty good about Atlas, but let's take a peek at control extenders. You get quite a few with the Atlas Toolkit (and more are on the way all the time). One I really like already is the AlwaysVisible extender. This allows you to take any control and say, "I want this to stay visible on my page as the user scrolls through it." Not only is this impressive as all get-out, it is actually quite useful. It gives you the power of ...

The Toolkit in action: Hooking up the CasdcadingDropDown

One of the things people regularly want to do is to create a "cascading" set of DropDownLists, where the value of each populates the values below. The "Atlas" Control Toolkit contains a great extender to make this super easy to set up. It does all of the population of the lists using an async call to a web service, which allows you to filter and cache the data on the server side and easily integrate it into your page. Go here to download and install the toolkit, and the Atlas April CTP if you ...
