In my case, dataset represents all the database, but I'm downloading data only when master row expanding. Ofcourse, highest level of the datagrid - result of the query runned by the user. Besides I don't know what it would be. So I have one table in dataset representing top level of the datagrid. Some fields are obligatory (foreign keys) but they are not represented in datagrid.

Interesting. I use my own master-detail using some DataGrids with one table inside and row filters in positions (DataGrid with some tables and master-detail inside isn't readable for our clients).
What are the advantages of using typed datasets in DataGrid with master-detail?

I need it to represent data in GridControl using master/detail...

Typed datasets are very huge. I use them only to CristalReports.

I'm using typed DataSet. Each time I need any data from DB I'm reading it in instance of this class. I have just 2 objects for now. Project is great

I use one dataset for a menu position (form) in my application. All extra information I set into extended properties of dataset or datatables. Generally it is clear to use as a parameter. If Your algorithms need to use few datasets it's proper too.
