Datagrid like control for client side paging - any suggestions?

[undercups]

My requirement is to have a datagrid like control which will have
client side paging i.e. no post backs.

So in VB.net I would query the database, load the control and send
the page to the client. The client would then handle ALL the paging
and sorting. The control will be read only. Just to make it
interesting - the number of columns is determined at run time with the
header for each column and the data for each row being returned by a
store procedure. I have managed to get an asp:DataGrid loaded as
above and on to the client but any paging etc causes a postback.
Have you any suggestions as to which control I can use?

A second and related question :-

Will the suggested control handle league table type data e.g. a
football league? I would want to show the division's name as a
header and then the teams and their statistics. Again the number of
columns is determined at run time and I would need to page between
each division of the league.

I happy to pay a modest sum for a suitable control or controls if
necessary. I have seen some really good looking examples but at $200
and more this is far too much for a one off development.

I looked as XLST but the the amount of learning and development needed
is beyond what I want to do.

I use Visual Studio as my develoment tool and ASP.NET 3.5 installed.
The likely hoster currently supports ASP 3.5.

Thanks in anticipation
