I'm using unbound generated data to fill listview or datagridview. My question is can I fill the rows of these objects with each iteration of a loop?

As of now the grids fully populate at the termination of the loop. I would like to again: Get data from instruments - see first row(1) cells fill with data - next loop - get data - see row(2) fill with data ect...

Or is drawing text to the form the best way to list generated data in the above manner?

Thanks
