C Sharp Scroll Bar
From Leo's Notes

The scroll bar in WPF has a property named {{code|ViewportSize which controls the size of the thumb. The {{code|ViewportSize is calculated using the formula below:
ViewportSize = range * percent / (1 - percent)
where
* {{code|range is the range of the scroll bar.
* {{code|percent is the percentage of content covered by the scroll bar between 0.0 and 0.99
You will need to ensure that the view port size is not infinity (from a division by zero).
