Introduction

You have already been using MSN Messenger to chat with friends, relatives, businesses, and much more. When someone signs in, a small popup window shows up on the right-bottom side of the screen, informing you that your friend X has just signed in. It is a nice way for MSN messenger to notify you about changes in the contacts online.

What about using the same technique on an ASP.NET page? In other words, suppose that you are monitoring a database table, where users place their orders online and you would like to be notified whenever a new request comes in to the database table.

In this article we will show you how to implement a messenger-like popup window whenever a new record is added to a database table. The popup will show on the bottom-right side of the screen on top of an ASP.NET page notifying you that a new record has been added. We will use ASP.NET 2.0 AJAX 1.0 Extensions and mainly the client library accompanies by the AJAX extensions.

Hey you...

Forget all about this... Open your mind... Enhance your World...

Using the JQuery and Ext JS will give you more facility in JavaScript coding.

And more... it's open source... do you need to know how incredible things have been done with...

http://jquery.com and http://extjs.com/

This will change your way to see de JavaScript and the Client-Side Programming.

Good Code for all.

IT is new feature but it would be much great if there is no web service implementation in the useage of this feature.

Using settimeout is not a good choice.

If you executing something on server and the StartChecking run, the server will execute twice the previously server process.

Hi Bilal,

Great article as usual. I have one question though. Is there any special reason that you used the UpdateProgress control?

Thanks,
