'Declaration Public Property RelativeHorizontalPosition As AnchorRelativeHorizontalPosition
public AnchorRelativeHorizontalPosition RelativeHorizontalPosition {get; set;}
The RelativeHorizontalPosition property defines the area of the document to which the value of the HorizontalAlignment or HorizontalOffset property is relative. For example, if AnchorHorizontalAlignment is set to 'Left', and RelativeHorizontalPosition is set to 'LeftMarginArea', the anchor's left edge is aligned with the left edge of the document's left margin. If AnchorHorizontalAlignment is set to 'Right', and RelativeHorizontalPosition is set to 'Page', the anchor's right edge is aligned with the right edge of the page, overlapping with the area outside the margin.
