    DisplayLastPage Method (GdViewer)
    In This Topic
    Displays the last page of the document currently loaded in the GdViewer control. You can use the CurrentPage property to determine the currently displayed page.

    The PageDisplayed and the PageChanged events are raised after the page has been successfully displayed and changed.

    Be aware that the SaveAnnotationsToPage method is called internally before each page change.

    Public Function DisplayLastPage() As GdPictureStatus
    public GdPictureStatus DisplayLastPage()
    public function DisplayLastPage(): GdPictureStatus; 
    public function DisplayLastPage() : GdPictureStatus;
    public: GdPictureStatus DisplayLastPage(); 
    GdPictureStatus DisplayLastPage(); 

    Return Value

    A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK. We strongly recommend always checking this status first.
    Please note that if the last page is already displayed, this method does nothing and returns GdPictureStatus.Aborted.

    Just to remind you that both the PageDisplayed and the PageChanged events are raised using this method.
