Now that's like good question. (Keep it up)

The answer is:
For the scenario you are looking for, you need to implement Observer Pattern[^] so that whenever chat history database updated you can send updates to respected user.

Find following links useful...

Implementing Observer Pattern in ASP.NET[^]
Applying Observer Pattern in .NET Remoting[^]

I have also found some articles with source code for developing chat application using ASP.NET however I am not sure whether they are using "Observer Pattern" or not.

Simple Chat Application in ASP.NET[^]
http://www.junnark.com/Articles/Build-a-Web-Chat-Application-Using-ASP-Net-LINQ-and-AJAX-CS.aspx[^]
http://aspalliance.com/1217[^]


Now, you can derive resolution of your problem from above links.
