How to UpdateCommand works on DataSets C++.Net 1.1

Question

Hello, Im looking for similar functionality on C# 2.0 (people works with typed datasets and foreign keys) as referenced in these posts : Post 1 or Post 2

My question is How to update changes on db where a row in Table "A" displayed on DataGrid "X" is modified (user change database value showed).

(*) Table "A" is joined with "N" Tables
(*) Consider that ForEach Estatement is not available yet on Net Fx 1.1

Thanks in Advances.
