Dmitry,
It should work. However, I suggest you to, on a new empty form:
-Show data sources window (Data\Show Data Sources).
-Connect and add your tables there
-Drag&drop one of the tables on to form (creates grid by default and adds needed BindingSource etc)
-Right click on table and select details
-Drag&drop again and this time you also get fields in detail mode
You can run and later check what it writes. Especially note that BindingSource has both DataSource and DataMember set. In your case probably you were missing the datamember.
PS: Have you ever thought of using Linq instead. Future is in there (say - my personal opinion).
