This probably worked fine with Delphi 5.
What is the equivalent for Delphi 6 ?
Thanks.

the class of the columns editor form is public and you can use in order it
to build your own property editor for columns. Here's how you should manage
it:
1. Add Dbcolned and colnedit units to the uses clause of the unit with
future property editor.
2. Add dsnide50.dcp and dcldb50.dcp to the requires clause of the package.
3. Write new property editor. Here's the code:
_____________________________________________
TNewDBGridColumnsProperty = class(TCollectionProperty)
public
function GetEditorClass: TCollectionEditorClass; override;
end;
function TNewDBGridColumnsProperty.GetEditorClass: TCollectionEditorClass;
begin
Result:=Dbcolned.TDBGridColumnsEditor;
end;
____________________________________________
4. Register it in this way:
RegisterPropertyEditor(TypeInfo(TDBGridColumns), TYourComponent,
'Columns', TNewDBGridColumnsProperty);
