In the Gantt control, you can set the vertical scroller position dynamically by clicking the custom button using the setScrollTop
method.
import { Gantt, Edit, Selection } from '@syncfusion/ej2-gantt';
import { Button } from '@syncfusion/ej2-buttons';
import { data } from 'datasource.ts';
Gantt.Inject(Edit, Selection);
let gantt: Gantt = new Gantt({
dataSource: data,
height: '450px',
taskFields: {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
child: 'subtasks'
},
splitterSettings: {
position: "50%"
}
});
gantt.appendTo('#Gantt');
let scrollBtn: Button = new Button();
scrollBtn.appendTo('#scrollTop');
document.getElementById('scrollTop').addEventListener('click', () => {
gantt.ganttChartModule.scrollObject.setScrollTop(300);
});
