ASP.NET 2.0 - How to build a Monitoring Application

[Auto]

Hello to everybody,

I would like to know how to build an ASP.NET 2.0 Application that show me
some data from a SQL Server Table and refresh it every one or two seconds ?
With autorefresh ? May be it is not so elegant...
I heard somthing about "Client Callback Manager", could this be good for
that ? If yes, how ?
Has the DataGrid got the autorefresh feature also, after the "Client
Callback Manager" for the sorting columns?
Can some good guy help me ?
Examples are welcomed

Thanks.
God bless you.

Auto.
