Caldera,

A non serialized dataset is in fact nothing more then a wrapper that holds
in opbjects nothing more than references to datatables and datarelations.

DataTables holds references to datacolumns and datarows.

DataRows hold references to items, and items contains data.

If you want to check this, then it will be a loop in a loop etc. However
completely depending what is in the dataset.

In my opinion are you mixing up a dataset with a recordset, while you are
speaking of records. A dataset is completely different from a dataset, the
dataset is not even a resultset.

Caldera,

As I wrote already in a (for) loop.

You wrote that you want the compare the contents of objects, those are in
the DataRow Item Collection.
