Description
The Value-based position of the thumb in the scrollable control.
The RelativeValue property is calculated relatively to Value, according to the following expression:
RelativeValue = (Value-Min)/(Max-Min-ViewportSize)
It can be in the range from 0 through 1. It can be used for positioning a thumb in a scrollable control, whose parameters are defined by the ValueRange properties (Value, Min, Max, ViewportSize, and Frequency).
