How does datagridview handle "Master / Detail"?

In .net objects like DataTable when you have two grids(Master and Detail) and add a row to the second one(Detail), The new row will have the Foreign-Key Values automatically.

How 开发者_C百科can i do it(I don't use DataTables because they suck)?

Here are some articles/papers on how Master-Detail relationship can be implememted with business objects(classes):
