nbnext - E2003 Undeclared identifier: 'nbnext'

[SergioFeitoza]

I have a  unidbnavigator and I am trying this code here  on event before action

procedure TMainForm.UniDBNavigator3BeforeAction(Sender: TObject;
  Button: TNavigateBtn);
begin
   if button = nbnext then pr_emfoco := uniMainModule.cdsselected.FieldValues['codigo'] + 1;
   if button = nbprior then pr_emfoco := uniMainModule.cdsselected.FieldValues['codigo']- 1;

end;

When I compile  I get the error Undeclared identifier: 'nbnext'

Two questions:

a) My uses clause is below. Is it missing any thing ?

b)  What is the code to do  a button of unidbnavigator visible/false in runtime ?

My USES clause

  Controls, Forms, Dialogs, uniGUITypes, uniGUIAbstractClasses,
