You can use OnActivePageChanging for this by setting the "ToPage" parameter to the ActivePage if you don't want to allow the page to be changed.

void Tform1::JvWizardActivePageChanging (TObject *Sender, TJvWizardCustomPage *ToPage)
    if (JvWizard->ActivePage == Page2 && !Gloga.IsEmpty())
        ToPage = JvWizard->ActivePage;
