ASP.NET Page-Scroll Following Div

I would like to implement a site wide alarm/notification system as in stackoverflow, where there is a horizontal div telling you when there is somebody answering your question ( the one on the top, yellow background notification ). The problem is, is there anything like that in the .NET control?

How could I开发者_开发知识库 achieve so? I succeeded building one, but it is a simple div, without following page scroll. I want a notification that follows page scroll so that it captures user attention.

Thanks in advance.

For the notification bar itself you can use a jQuery plugin called jbar: http://tympanus.net/codrops/2009/10/29/jbar-a-jquery-notification-plugin/

The other piece is you are going to have to use Comet to know when something has happened server side in the client. For that I reccomend using Long Polling with SignalR:
