RadTrackBar
Represents a track bar. The trackbar class is essentially a simple wrapper for the RadTrackBarElement. All UI and logic functionality is implemented in the RadTrackBarElement class. The RadTrackBar acts to transfer the events to and from its corresponding RadTrackBarElement instance. The RadTrackBarElement may be nested in other telerik controls.
