Prevent_default_scroll doesn't work

Gantt
#1

If you check the code, it’s not used anywhere. (v7.1.12).

Are there any alternative methods for this functionality?

#2

Hello,

Thanks for noticing the issue. The prevent_default_scroll config is deprecated since version 5.0. It seems that we didn’t update the documentation’s article. We will fix it ASAP.

Is there a current option that will prevent outer scrolling?
For example, check here: DHTMLX Snippet Tool

What happens:
When I’m scrolling using the mouse wheel inside the chart, after I reach the end of the chart, the outer container will scroll too.

What I would like to happen:
When I’m scrolling using the mouse wheel inside the chart, the outer container should never scroll.

Workaround:
I’ve found that if I disable “onwheel” on the gantt container, it achieves what I want, but maybe this should be an option in the gantt chart as well. Example here: DHTMLX Snippet Tool
Only difference is this:
document.getElementById(‘gantt_here’).onwheel = function(){ return false; }

Hello,

Currently, there is no built-in way to prevent scrolling the container that contains Gantt.

Workaround: DHTMLX Snippet Tool ;

Thanks for your workaround. I will tell the dev team to add this feature,
but I can’t guarantee that it will be implemented in the future.
