The ASPxClientTrackBar object is the client-side equivalent of the ASPxTrackBar control. This object exposes the control’s comprehensive client-side API.

ASPxClientTrackBar implements functionality that allows you to execute the following track bar related actions on the client.

• Manipulate drag handle positions
• Respond to end-user changes in drag handle position
• Obtain track bar item information

In addition, ASPxClientTrackBar exposes the common client API, which it inherits from its direct ansestor - ASPxClientEdit.
