Remarks

Dependencies specify relationships between tasks. This allows a user to define when a task should begin or end in relation to another task.

A task that depends on another task’s completion is a successor task. A task that defines when dependent task should start or finish is a predecessor task. A single task can have one dependency or more.

TdxGanttControlTaskPredecessorLink members allow you to do the following:

Get the lag time format (IsElapsedLagFormat and IsPercentLagFormat)
Specify the task delay time and its measurement units (LinkLag and LagFormat)
Access the predecessor task by its identifier (PredecessorUID)
Obtain the successor task (Task)
Specify the dependency type (Type)

The Items property
The Append and GetItemByPredecessorUID functions
