    In This Topic
    Sets the required position of both the horizontal and the vertical scrollbars in one step, in other words, both scrollbars move to the newly specified coordinates. The coordinates are expressed in pixels and they are related to the actual document area of the currently displayed page of the document displayed in the GdViewer control.
    Syntax
    'Declaration

       ByVal NewHPos As Double, _

        NewHPos: Double;
        NewVPos: Double
    ); 
    public function SetScrollBarsPosition( 
       NewHPos : double,
       NewVPos : double
    );

       double NewVPos
    ) 
    public:
    void SetScrollBarsPosition( 
       double NewHPos,
       double NewVPos
    ) 

    Parameters

    NewHPos
    The new horizontal coordinate, in pixels, where the horizontal scrollbar is to be moved.
    NewVPos
    The new vertical coordinate, in pixels, where the vertical scrollbar is to be moved.
    Remarks
    Please note that if the newly specified values are out of the expected range, the toolkit sets the current values to the nearest one (means minimum or maximum ones) without reporting any error. Otherwise, you can regularly apply the GetStat method to determine if this method has been successful.

    Just to remind you, that all coordinates are 0-based with the origin being in the top left corner in the document pages area and they are related to the current page determined by the CurrentPage property.

    Example
    How to set the scrollbar to its maximum available position to allow to display the bottom right corner of the document.
    'We assume that the GdViewer1 control has been properly integrated
    'and your document has been properly displayed as well.
    If GdViewer1.HorizontalScrollBarVisible OrElse GdViewer1.VerticalScrollBarVisible Then
        GdViewer1.SetScrollBarsPosition(GdViewer1.GetHorizontalScrollBarMaxPosition(), GdViewer1.GetVerticalScrollBarMaxPosition())
    End If
    //We assume that the GdViewer1 control has been properly integrated
    //and your document has been properly displayed as well.
    if (GdViewer1.HorizontalScrollBarVisible || GdViewer1.VerticalScrollBarVisible)
        GdViewer1.SetScrollBarsPosition(GdViewer1.GetHorizontalScrollBarMaxPosition(), GdViewer1.GetVerticalScrollBarMaxPosition());
