Gantt
#1

Hello, I would like to disable the selection with Ctrl and Shift in my Gantt chart and use a checkbox column for selection instead. I have added the checkbox column, but I can’t manage to disable Ctrl and Shift. Can anyone help me? Thank you.

Hello Enrico,
I suppose the easiest way to do that is to use the onTaskClick event handler:

You can use the unselectTask method if you didn’t click on the checkbox:

Here is an example of how it can be implemented:
