Property Value
Type: System.Double
The y-coordinate of the top of the scrollbar track as it is rendered in the display (excluding the scroll buttons at the top and bottom).
Remarks
When mapping from scrollbar coordinates to positions in the scrollbar's track, the correct mapping is:
pixel position = (scrollbar coordinate * TrackSpanHeight / (Map.Maximum + Map.ViewportSize)) + TrackSpanTopscrollbar coordinate = (pixel position - TrackSpanTop) * (Map.Maximum + Map.ViewportSize) / TrackSpanHeight.
