I'm developing handheld application written in VB.NET, with .sdf database.
I have following problem: on one form I have combo box (which relates to the primary key) and several text boxes (other fields in the table). When I enter data in the database I can retrieve data from the database during one session, but during following session, my data are gone (I can't retrieve data from the database).
Data binding is performed via properties toolbox.

Any idea, anyone?

Sorry for the long text, but this really bugs me.
