Async dataset populating.....

I have some search screens in my app which can, with certain search params,
bring back thousands of rows, and can take ages to populate. So I am trying
to find a better way of them operating. One idea is to batch the results up.
So I could go and get the 1st 50 rows and populate the datagrid with those,
then when they scroll to the last of these 50 it goes and gets the next 50.

That got me thinking asynchronous. Would it be possible to fire off a
process that went to get all 10000 rows for example, but return them every 50
or so when it had them. So the process would fire off, and return the first
50, the user is free to peruse those while the process is busy in the
background getting the rest of the records, spitting them into the datagrid
every 50.

Is any of this possible? How?

Cheers

Steve,

The method you ask for is in my idea "Paging". It is not assynchronous. For
ASPNet it is a part of the datagrid methods. For windowsforms we have some
samples on our website, but the name of that website is VB-Tips, so I assume
that you understand that there are no C# samples.
