Hello Ash,
We will introduce new editing modes for the Gantt in our 3.1 version release which is due in early March. It will be possible to set the edit mode of the Gantt TreeList to none, thus, disable editing.
Additionally, we will add new events including the OnEdit event for Gantt. The OnEdit event will give developers the ability to cancel edit based on a condition.
I hope you find the above information useful and the release date fits your time frame.
Regards,
Apostolos

Hey Ash,
as you might seen in the news, Editable is possible now :)
You can add the "Editable" for each Column now.
Happy coding!
