Fixed duration in the Gantt chart

edited 12/09/19 in Archived 2016 Posts

Hi all,


I'm evaluating duration time of every tasks. In the sheet, I set a duration time, a start date and the end date is adjusted accordly. If I want to change the start date, the end date will be updated and vice-versa. It's fine.


However, in the Gantt chart, when I'm touch a gantt bar to change the task start, it's really easy that I will change the task duration in opposite of the task start/end time, that is what I want. It's a trouble, because the duration was calculated after a specification of the task and an evaluation of the proposed solution, so it should be fixed and not so easy to edit for a mistake.


Can I do something to fix the duration time in a way that if someone want to use the gantt chart to move the start time of the task, the duration will be mantained?

    Good question - there is not a way to prevent users from adjusting the duration by dragging the Gantt bars. I would recommend clicking in the body of the bar rather than the edges. The edges will change duration, while the body will change the start and end dates.

    The problem is that usually the gantt bar is really short, so it's impossible to click in the middle of the bar. A great option could be to choose the gantt behaviour on click at the edge bar: change duration or translate start/end time.


    Thank you Travis,
