You are either going to have to supply a default value for the new
record's ProvinceState field that is in the dropdown, or (my preference) add an
entry to the dropdown to indicate a blank value. Typically it has the caption
"-select-" or something like that. Then in your business logic validation you
simply check for that placeholder value, and disallow the save if they haven't
made a selection.
Dropdowns are wonderful UI elements for selecting from a small list of
choices, but they come with them the limitation that all bound values must be
present in the dropdown's choices, or else it cannot display anything.
