How to Create a DB component with FIELD selector

Hi, I want to create a DB component where I select the Datasource. That works correctly, but when I want to select the FIELD (TFIELD) I get a list of ALL fields. I only want to have the fields from the source I've selected in the object inspector.

Anyone knows How?

Yes the property is declared like that, I want to have a combobox with the fields from the table in the property editor.

I don't have a DBREG anything :(

Please show me the exact declaration and get/set methods and the internal field declaration.

I have it in <delphidir>\Source\Property Editors\dbreg.pas
(Delphi 5 Enterprise)

Thanx, this method :

RegisterPropertyEditor(TypeInfo(string), TComponent, 'DataField', TDataFieldProperty);

Is all I needed :)

It's strange that you needed it.

Anyway... You don't seem to be interested in a complete solution. Good luck.

I don't have Delphi 5, just Delphi 4.
Delphi 4 has no examples about the subject.
Complete solutions take the fun of programming away ;)

But my component works fine now :)
Thanks!
