It works the same with the TIBODatasets as it does with the VCL
datasets. It seems to me you haven't read up the Delphi help on how
to set up this control. It involves TWO datasources - one for the
dataset that wants to do the looking up (Datasource and Datafield
properties) and one for the dataset that is supplying the values for
the lookup (Listsource and Listfield properties).

Reading up the Delphi help should clarify for you whether
TDBLookupComboBox is really the component you want for this task...at
first sight of your description, I tend to think not.
