Event Markers in React Gantt Component
27 Jun 202424 minutes to read
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';
function App (){
const taskFields = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
parentID: 'ParentID'
};
const eventMarkerDay = new Date('4/10/2019');
return <GanttComponent dataSource={data} taskFields={taskFields} height = '450px'>
<EventMarkersDirective>
<EventMarkerDirective day={eventMarkerDay} cssClass='e-custom-event-marker' label='Project approval and kick-off' ></EventMarkerDirective>
</EventMarkersDirective>
<Inject services={[DayMarkers]} />
</GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));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';
function App (){
const taskFields: any = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
parentID: 'ParentID'
};
const eventMarkerDay: Date = new Date('4/10/2019');
return <GanttComponent dataSource={data} taskFields={taskFields} height = '450px'>
<EventMarkersDirective>
<EventMarkerDirective day={eventMarkerDay} cssClass='e-custom-event-marker' label='Project approval and kick-off' ></EventMarkerDirective>
</EventMarkersDirective>
<Inject services={[DayMarkers]} />
</GanttComponent>

</html>Managing event marker overlapping in react gantt component
In the EJ2 Gantt control, it is possible to customize multiple eventMarkers for the same date. However, by default, in such scenarios, these markers may overlap each other, resulting in visual clutter. To manage this, the following sample code demonstrates how to utilize the Gantt dataBound function to obtain label and arrow classes. It performs a loop action to fulfill the current requirement and to avoid overlapping. For further clarification, the code snippet below illustrates the flow of its implementation.
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';
function App (){
const taskFields = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
parentID: 'ParentID'
};
function dataBound() {
let labeltop = 100;
let rightarrow = 110;
const eventMarkerLabels = document.getElementsByClassName("e-span-label");
const eventMarkerArrows = document.getElementsByClassName("e-gantt-right-arrow");
for (let i = 0; i < eventMarkerLabels.length; i++) {
const label = eventMarkerLabels[i];
const arrow = eventMarkerArrows[i];
if (label && arrow) {
label.style.top = labeltop + "px";
arrow.style.top = rightarrow + "px";
}
labeltop += 35;
rightarrow += 35;
}
};
const eventMarkerDay1 = new Date('4/10/2019');
const eventMarkerDay2 = new Date('4/10/2019');
return <GanttComponent dataSource={data} taskFields={taskFields} height = '450px' dataBound={dataBound}>
<EventMarkersDirective>
<EventMarkerDirective day={eventMarkerDay1} cssClass='e-custom-event-marker' label='Project approval and kick-off' ></EventMarkerDirective>
<EventMarkerDirective day={eventMarkerDay2} cssClass='e-custom-event-marker' label='Project approval and kick-off' ></EventMarkerDirective>
</EventMarkersDirective>
<Inject services={[DayMarkers]} />
</GanttComponent>

Label positions in react gantt control
The EJ2 Gantt chart offers powerful features for customizing various labels position within the chart, enabling users to present relevant project information clearly. In EJ2 Gantt chart, labelSettings feature provides three key options for label customization: rightLabel, taskLabel, and leftLabel. Label positions can be initialized by using the labelSettings property.
The following code example shows how to add label positions in the gantt control.

When eventMarkers are given in consecutive dates and zoomToFit is performed, they may overlap. To avoid this, you can update the position of the eventMarkers in the dataBound and actionComplete events so that they are not overlapped and are visible to read.
The following code example demonstrates how to display event markers in a stacked manner in the Gantt control.

};
const updateEventMarker = () => {
const eventMarkerLabels = document.getElementsByClassName('e-span-label');
const eventMarkerArrows = document.getElementsByClassName('e-gantt-right-arrow');
const label = eventMarkerLabels[1];
const arrow = eventMarkerArrows[1];
label.style.top = 90 + "px";
arrow.style.top = 100 + "px";
};

updateEventMarker();
