Holidays in EJ2 JavaScript Gantt control

2 May 20234 minutes to read

Non-working days in a project can be displayed in the Gantt control using the holidays property. Each holiday can be defined with the following properties:

  • from: Defines start date of the holiday(s).
  • to: Defines end date of the holiday(s).
  • label: Defines the description or label for the holiday.
  • cssClass: Formats the holidays label in the Gantt chart.

To highlight the holidays, inject the DayMarkers module into the Gantt control.

The following code example shows how to display the non-working days in the Gantt control.

ej.gantt.Gantt.Inject(ej.gantt.DayMarkers);

var ganttChart = new ej.gantt.Gantt({
        dataSource: GanttData,
		height:'450px',
	    taskFields: {
            id: 'TaskID',
            name: 'TaskName',
            startDate: 'StartDate',
            duration: 'Duration',
            progress: 'Progress',
            parentID: 'ParentID'
        },
		 holidays: [{
            from: "04/04/2019",
			to:"04/05/2019",
            label: " Public holidays",
			cssClass:"e-custom-holiday"
            
        },
		{
            from: "04/12/2019",
			to:"04/12/2019",
            label: " Public holiday",
			cssClass:"e-custom-holiday"
            
        }]
});
ganttChart.appendTo('#Gantt');
