Code Examples: Delete All Tasks
The Gantt control always contains a root task, and an attempt to delete it causes an exception. The following code example iterates through all tasks and deletes all tasks except for the root:
while dxGanttControl1.DataModel.Tasks.Count > 1 do
dxGanttControl1.DataModel.Tasks.Delete(1);
Alternatively, you can call the data model’s Tasks.Reset procedure:
