    Hello,

    is it somehow possible to prevent that more than one root task can be created or only certain tasks can be deleted? My problem is that inside my gantt chart the root task represents some kind of project planning and all the child tasks are the different tasks of this project planning. So I want to prevent that the user can delete this root task or create other root tasks by drag and drop etc. This is a problem because I can only cancel e.g. the OnTaskDelete-event with some kind of data validation but the OnTaskUpdate events are fired before the OnTaskDelete-event. As a  consequence incorrect data is stored inside the updated tasks (e.g. the false OrderId), because the deletion of the root task is cancelled.

    I really hope you can help me. Thank you very much.

    Kind regards,

    Felix
