VB.Net - DataGrid Scroll and Show Detail

Good Day Experts!

I have a DataGrid with "higher" level data in the rows.  I want to be able to show the "detail" level data related to each row in another DataGrid while automatically iterating through the DataGrid with a button click to start the process.  

I don't think I can hit the database each time I get to a new row of the "higher" level data.  It "feels" like I need to have all the potential detail local in a DataTable.  There will be about 300 records of "higher" level data and probably like 900 records of "detail" level data at the most.

Can anyone think of a way I could achieve this? Please ask questions as my explanation may not be clear.
