Just to add to what has been said already...

Take a look at the LookupCombo sample application that comes with IBO.
There you will see an example of using the CustomPopup property of
TIB_LookupCombo.

It has a separate TIB_LookupList control dropped onto the form that
will be used as the popup for TIB_LookupCombo (instead of the default
internal popup).

This allows you to get direct access to pretty much all of the
properties and events of the grid to be displayed, including the
OnDrawCell event handler and the DefDrawBefore property that Helen
spoke of.
