The event markers in the Gantt component is used to highlight the important events in a project. Event markers can be initialized by using the eventMarkers property, and you can define date and label for the event markers using the day and label properties. You can also customize it using the cssClass properties. The following code example shows how to add event markers in the Gantt component.
To highlight the days, inject the DayMarkers module into the Gantt component.
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent, Inject, DayMarkers, EventMarkersDirective, EventMarkerDirective } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
class App extends React.Component {
constructor() {
super(...arguments);
this.taskFields = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
child: 'subtasks'
};
this.eventMarkerDay = new Date('4/10/2019');
}
render() {
return <GanttComponent dataSource={data} taskFields={this.taskFields} height='450px'>
<EventMarkersDirective>
<EventMarkerDirective day={this.eventMarkerDay} cssClass='e-custom-event-marker' label='Project approval and kick-off'></EventMarkerDirective>
</EventMarkersDirective>
<Inject services={[DayMarkers]}/>
</GanttComponent>;
}
}
;
ReactDOM.render(<App />, document.getElementById('root'));<!DOCTYPE html>
