John,

This sounds like a multi-part question. How are you getting the data? How do you save the data to the database? Stored Procs? Once you merge the data back to your DataTables, they'll be considered changed rows and you should be able to update the database the same way you have been. How are you merging the data back to the DataTables? Without some idea of how you're going about these tasks, there's no simple answer.
