Property Value

Type	Default
TdxPDFViewerNavigationPaneActivePage	apNone

Remarks

Use this property to expand or collapse the Navigation pane and to switch between its available pages. The ActivePage property value changes to apNone if an assigned page is empty. For instance, if the loaded PDF document has no file attachments, the Attachments page is empty. In this case, if you assign apAttachments to the ActivePage property, its value changes to apNone, and the Navigation page collapses. Refer to the TdxPDFViewerNavigationPaneActivePage type description for detailed information on all available options.

Users can click Navigation pane’s visible page tabs to switch between all available pages.

The default ActivePage property value is apNone.
