perhaps I missed a point about that component, but I always get an empty drop down list when connecting to a dataset. Do I have to populate it manually?
Sorry, mistaken it with some kind of lookupdropdown. Unfortunately this doesn't exist.
TDBAdvMultiColumnDropDown is a DB-aware edit control (like a TDBEdit) with the difference that a value can be picked from the dropdown. The dropdown is not filled by a dataset. It is filled via TDBAdvMultiColumnDropDown.Items.
