GanttView enables users to highlight a specific day of week by setting its back color. For instance, the weekends in a gantt view can be highlighted in a different color to distinguish them from workweek. This can be achieved in code by subscribing the PaintDay event and setting the BackColor property to color specific days.
The following image shows a GanttView with weekends highlighted by a different color.
