Hi,
It's happening because you're not passing an element, you're passing the instance which is not an element
So you'd need to pass the gantt element
Like this for example
useEffect(() => {
if (ganttRef.current) {
EventHelper.on({
element : ganttRef.current.instance.element,
delegate : '.b-grid-row',
click : () => {
console.log('click');
}
});
}
}, []);
This should be working for you.
Best of luck,
Tasnim
