get child notes without dataset. dataset designer

Question

I used the dataset designer to access the database.
And I do not understand why I'm getting no data.

Please tell me how to fix that

usersTableAdapter usersTA = new usersTableAdapter();
var usersTable = new users.usersDataTable();
usersTA.Fill(usersTable);

partnersTableAdapter partnersTA = new partnersTableAdapter();
var partnersTable = new users.partnersDataTable();
partnersTA.Fill(partnersTable);

VK_BDayParser.users.usersRow row = usersTable.FindByid(currentItem.id);
var partners = row.GetpartnersRows();

partners is always zero-lenghted array, but in the database table partners has many rows
