I’m dynamically loading dhtml gantt to display my data when expand is clicked. After fetching the data i’m calling gantt.parse(data); gantt.render(); to display the loaded data. However after the data is rendered the scrollbar always moves to starting of gantt.
How we can maintain the scroll position ?
Also i have tried to do this using gantt.showTask() but it makes the screen look jumpy. It goes to the top and again comes back to the task which doesn’t look good. Is there any other approach ?
