Pivot datatable for GridView and Update

Hello, I have seen several articles on Pivoting data in a datatable to bind to a data grid.  Im using the one referenced in this link:

http://geekswithblogs.net/dotNETvinz/archive/2009/05/10/pivot-data-in-gridview---a-generic-pivot-method-with.aspx

I have the 2 datatables as in the example.

The original normalized version 'dt' with a sqldataadapter.
and the pivoted version 'pivotedTable' as the datasource for the gridview.

I would like to save the data modified in the gridview back to the database in its normalize form.  Possibly using the 'dt' datatable and dataadapter.  

My thoughts are:
use 'getchanges' from pivotedTable:

        Dim changedRecords As System.Data.DataTable
        changedRecords = dt.GetChanges

Then use 'changedrecords' datatable to update the original dt, and da.update to update the database.

My question is: is this a reasonable approach?, is there a better way?.  Does someone have an example.

Im using winforms and vb.net but c++ is ok also.

thanks very much.

I think that is a reason able approach. Given that data in PivotedTable can not be saved back to the DB using adapter then you have two options

1) Getchanges and apply to dt then save dt using adapter
2) Getchanges, loop and save changes to db manually.
