Drag Handles are draggable elements that can be moved by end-users along the track to change ASPxTrackBar's current value (value range).
When the TrackBarProperties.AllowRangeSelection is set to true, an ASPxTrackBar displays two drag handles (main and secondary) to support the value range selection. The main drag handle specifies a range start position. The secondary drag handle specifies a range end position.
The table below lists the main members that affect element appearance and functionality.
