Сразу оговорюсь, я в этом деле далеко не профи.

Создал новый проект.
все делалось через GUI.
1. Добавил sqlconnection, все указал как надо.
2. Добавил sqldataadapter, аналогично.
3. В адаптере сгенерил dataset. Preview показал все то что надо.
4. Влепил dataGrid Control. В параметре Data Source указал datasetname.tablename (короче как они предлагали)
Как я понимаю после запуска все должно пахать.
Запускаю - банан.
Появляется пустой датагрид, с названиями колонок. Абсолютно без данных. Можно только добавлять и прыгать с бубном вокруг.
Может я чего то не догоняю? Неужто надо дополнительно прописывать вставку самих данных??

Заранее благодарен.
