In my previous article, I have presented the AJAX Grid and a Generic Pager, which mimics the built-in GridView control on the client side. In this part, I will provide details about developing Ajax Controls with the ASP.NET AJAX Framework.Although the main goal of this article is to show you how to develop ASP.NET AJAX Controls with the ASP.NET AJAX Framework, it's really worth to read this, even if you are only interested in ASP.NET AJAX Framework instead of developing controls.

In the first part of this series, we started with an example of a simple web page that displays a Virtual Earth map on screen. The purpose of the code was to highlight some bad habits in writing markup and JavaScript code. We promised ourselves to rewrite the same page in order to take advantage of ASP.NET and the new AJAX framework. This is what we are going to do starting from part two of this series....

In the second part of this series, you saw how to create client Controls and Extenders using the Microsoft Ajax Library and the ASP.NET AJAX server framework. Now, you will learn how to make asynchronous calls to the server in order to process data without reloading a web page.The Web uses a stateless protocol (HTTP) to exchange data. As a consequence, a user interacts with a web page through multiple request-response transactions. Typically, an action performed by the user (such as submitting a...

Couple of weeks ago, I created a DHTML control, based on the DHTML posted on www.dynamicdrive.com. It was a data-bound control, and it was a nice experience. I had to go through all the details of amazing "Developing Microsoft ASP.NET Server Controls and Components", and I learnt a lot of new things. But, after I start reading about AjaxControlToolkit, and started analyzing the code, I realized that there is a lot easier way to achieve the same thing, in a lot more elegant way....

My website is a rich social network that offers users many web forms to fill. For example, users can post articles and edit lengthy profiles. Often they click on a link that takes them away from the page or press the wrong key (e.g. backspace that navigates to the previous page). In both cases their changes get lost. And it is always frustrating to have to re-enter the same text twice. Wouldn't it be nice to warn the user that he has unsaved data and give him an opportunity to cancel, then save ...

ASP.NET Atlas has a timer server control which periodically postbacks to the server. However, the TimerControl has a bug that prevents it to be stopped from server side code during partial rendering. Time and again, I encounter the question in Atlas forums which ask for a workaround to this bug. This article is based on my post in Atlas forums, and has detailed explanation on how to solve this problem. Hopefully, the issue will be resolved in a future version of Atlas....

Sometime back, I came across the Spell with flickr web page. You can enter some text in the web page and the text is spelled using images from the oneletter and onedigit group in flickr. This webpage uses PHP. I was experimenting with the concept of bridges in Atlas to develop a mash-up. In my actual mash-up application, I needed something similar to the Spell with flickr web site. The result is this extender which allows you to display the text inside an HTML element as random images, represent...

This is a custom webcontrol that shows the progress of long sequential tasks using AJAX to refresh the page.
I needed this for a web form where the user would click a button and the system would send e-mails for a group of people. To enhance the responsiveness of the system, I had the idea of showing the progress of each e-mail being sent. Then I realized this idea could be used in many other situations where tasks need to be synchronously executed....

The HTML file input control and the ASP.NET FileUpload control derived from it have important limitations including poor graphic design and security restrictions. Our objective is to provide a better file upload component. This function is fulfilled by a MultiUpload control which improves on Google mail’s file attachment experience. Our environment is ASP.NET 2.0 on Windows and IIS and our MultiUpload control uses ASP.NET Ajax Extensions 1.0 which you can download and install from http://www.asp...

My open source Ajax Web Portal www.dropthings.com has an ASP.NET Ajax Extender which provides multi-column drag & drop for widgets. You can see similar drag & drop behavior in commercial Ajax Start Pages like Pageflakes. The Extender allows reordering of content on the same column and drag & drop content between columns. It also supports client side notification so that you can call web service and store the position of the content behind the scene without producing (async) postback....
