GanttChartItemSource Class Reference
GanttChartItemSource
public class GanttChartItemSource : GanttChartItemManagerGantt Chart item manager that hosts items and dependencies within exhaustive arrays. May be used instead of an object inheriting from GanttChartItemManager when the data set is small and the runtime performance is not a concern.
