public ValueList NextTasks {get;}
Remarks
The NextTask property is a TList component that holds the Gantt bar index each Gantt bar is connected to.
When a Gantt bar is added to TGanttSeries, it's NextTask value is assigned to -1 by default. That means the Gantt bar is NOT connected to any other Gantt Bar.
You need to set a valid bar index to NextTask.
Example
[C#]
You can use the following code to connect two gannt bars with line:
Gantt1.FillSampleValues(6)
Gantt1.NextTasks(1) = 5 'Connect 2nd bar to 6th bar
