Header rows in EJ2 JavaScript Schedule control

27 Apr 202319 minutes to read

The Timeline views can have additional header rows other than its default date and time header rows. It is possible to show individual header rows for displaying year, month and week separately using the headerRows property. This property is applicable only on the timeline views. The possible rows which can be added using headerRows property are as follows.

  • Year
  • Month
  • Week
  • Date
  • Hour

The Hour row is not applicable for Timeline month view.

The following example shows the Scheduler displaying all the available header rows on timeline views.

var scheduleObj = new ej.schedule.Schedule({
    width: '100%', height: '550px',
    selectedDate: new Date(2018, 11, 31),
    startHour: '09:00',
    endHour: '13:00',
    headerRows: [
        { option: 'Year' },
        { option: 'Month' },
        { option: 'Week' },
        { option: 'Date' },
        { option: 'Hour' }
    ],
    views: ['TimelineWeek'],
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

Display year and month rows in timeline views

To display the timeline Scheduler simply with year and month names alone, define the option Year and Month within the headerRows property.

var scheduleObj = new ej.schedule.Schedule({
    width: '100%',
    height: '550px',
    selectedDate: new Date(2018, 11, 31),
    headerRows: [{ option: 'Year' }, { option: 'Month' }],
    currentView: 'TimelineMonth',
    views: [{ option: 'TimelineMonth', interval: 24 }],
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

Timeline view displaying dates of a complete year

It is possible to display a complete year in a timeline view by setting interval value as 12 and defining TimelineMonth view option within the views property of Scheduler.

var scheduleObj = new ej.schedule.Schedule({
    width: '100%',
    height: '550px',
    selectedDate: new Date(2018, 0, 1),
    headerRows: [
        { option: 'Month' },
        { option: 'Date' }
    ],
    views: [{ option: 'TimelineMonth', interval: 12 }],

Customizing the header rows using template

You can customize the text of the header rows and display any images or formatted text on each individual header rows using the built-in template option available within the headerRows property.

var instance = new ej.base.Internationalization();
window.getDateHeaderText = function (value) {
    return instance.formatDate(value, { skeleton: 'Ed' });
};
window.getYearDetails = function (value) {
    return 'Year: ' + instance.formatDate(value.date, { skeleton: 'y' });
};
window.getMonthDetails = function (value) {
    return 'Month: ' + instance.formatDate(value.date, { skeleton: 'M' });
};
window.getWeekDetails = function (value) {
    return 'Week ' + ej.schedule.getWeekNumber(value.date);
};

var scheduleObj = new ej.schedule.Schedule({
    width: '100%',
    height: '550px',
    selectedDate: new Date(2018, 0, 1),
    headerRows: [
        { option: 'Year', template: '#year-template' },
        { option: 'Month', template: '#month-template' },
        { option: 'Week', template: '#week-template' },
        { option: 'Date' }
    ],
    views: [{ option: 'TimelineMonth' }],
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');
