Value	Description	Example
apNone	The Navigation pane is collapsed (that is, has no active page). It is displayed as a narrow vertical bar with page tab glyphs. The PDF Viewer control’s OptionsNavigationPane.ActivePageState property updates to wsMinimized in this mode. The OptionsNavigationPane.ActivePage property value changes to this value if the target Navigation pane’s page is empty.
apThumbnails	The Navigation pane shows the Thumbnails page in the normal state, that is, automatically assigns wsNormal to the control’s OptionsNavigationPane.ActivePageState property.
apBookmarks	The Navigator pane shows the Bookmarks page in the normal state, like in the apThumbnails mode. The control’s OptionsNavigationPane.ActivePage property value changes to apNone if there are no bookmarks in the loaded document.
apAttachments	The Navigator pane shows the Attachments page in the normal state, like in the apThumbnails and apBookmarks modes. The control’s OptionsNavigationPane.ActivePage property resets to apNone if the loaded document has no file attachments.
