If in your application you use controls oriented to displaying both tasks (GanttChartView or GanttChartTaskListView) and resources (ScheduleChartView or ScheduleChartResourceListView), and you want a way to synchronize the colors (appearance) of the task bars displayed within the two charts, you should set IsItemAppearanceApplied property to true for both controls, and IsTaskAppearanceApplied property also to true for the resource oriented control.
