By default, the state of all Gantt chart groups is set to "expanded". You can keep the children collapsed by setting Expanded = false when loading tasks.

Tell me pls, can the task remember its position? If users opened it, so that it remains open and does not collapse?

The tree state is synchronized with the server during CallBacks and PostBacks - you can read the current Expanded state of each task (Tasks property).
