Is it possible to add multiple predecessors for a GanttTaskInfo? If I do the following,
parentTask63.PredecessorTask = parentTask20;
parentTask63.PredecessorTask = parentTask21;
the last predecessor task overrides the previous one. What I would like is for the parentTask63 to have parentTask20 and parentTask21 as predecessors. Is this possible? If so please let me know how.
