You seem confused. Are you talking about TIBOQuery or TIB_Query?

If TIB_Query, you are asking the impossible.

TIBOQuery is a TDataset descendant that allows you to use the Delphi
datalinks so that you can use controls and 3-P stuff that depend on
those. The native IBO stuff conveys the datalinks info to its own
datasource and thence to its controls, under an entirely different
system. The native IBO data access objects don't even touch the native
Delphi TDataset so there is nothing in the architecture that can make the
datalinks to the Delphi TDatasource. The IBO datasource has a whole world
of server-centric stuff in it that is not addressed at all by the
TDataset/TDatasource architecture.

If you look at the Help file, you can track the inheritance trees of the
components by clicking on the Hierarchy link. If you compare the native
IBO hierarchy with the native Delphi hierarchy, you'll see the
"barriers". And that's without even starting to think about DBExpress
that's coming along in Delphi 6 to replace the BDE for C/S database
