Volume Control

Volume : %.

This demo shows how other controls can be added around the gauge to provide a functional interface, not just a visualization of the data. In this case a RadSlider is positioned slightly on top of the gauge to mimic the Windows volume control. The positioning takes into account the dimensions of the gauge and compensates for the paddings the gauge has.
