The C1ProgressBar control's track runs the length of the control. By default, the track appears in only one color (usually gray), indicating that no process has been started yet. If a process has been started, track will appear in two contrasting colors, one of which indicates the amount of the process that has completed and the other of which indicates the amount of the process that is left.

The size of the C1ProgressBar track is set using the Width and Height properties. The track can be vertical or horizontal in orientation.
