C1RangeSlider is a simple control that enables you to select a range of numeric data with lower value thumb and upper value thumb. These thumbs define start and end values of the range. When you drag the thumb towards the left (or down) on Range Bar you reduce its value, and you increase the value when drag it towards the right (or up). The control has minimum and maximum bounds for thumb values. Thumb value cannot be less than the minimum bound and more than the maximum bound. Moreover, lower value cannot be greater than the upper value, and otherwise.

The control can be oriented horizontally or vertically.
