Cell customization in EJ2 JavaScript Scheduler control

3 Mar 202524 minutes to read

The cells of the Scheduler can be easily customized either using the cellTemplate or renderCell event.

Customizing cells in all the views

It is possible to customize the appearance of the cells using both template options and renderCell event on all the views.

Using template

The cellTemplate option accepts the template string and is used to customize the cell background with specific images or appropriate text on the given date values.

window.getMonthCellText = function (date) {
  if (date.getMonth() === 10 && date.getDate() === 23) {
    return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/birthday.svg" />';
  } else if (date.getMonth() === 11 && date.getDate() === 9) {
    return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/get-together.svg" />';
  } else if (date.getMonth() === 11 && date.getDate() === 13) {
    return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/birthday.svg" />';
  } else if (date.getMonth() === 11 && date.getDate() === 22) {
    return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/thanksgiving-day.svg" />';
  } else if (date.getMonth() === 11 && date.getDate() === 24) {
    return '<img src="https://ej2.syncfusion.com/demos/src/schedule/images/christmas-eve.svg" />';
  } else if (date.getMonth() === 11 && date.getDate() === 25) {
    return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/christmas.svg" />';
  } else if (date.getMonth() === 0 && date.getDate() === 1) {
    return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/newyear.svg" />';
  } else if (date.getMonth() === 0 && date.getDate() === 14) {
    return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/birthday.svg" />';
  }
  return '';
};

window.getWorkCellText = function (date) {
  var weekEnds = [0, 6];
  if (weekEnds.indexOf(date.getDay()) >= 0) {
    return "<img src='https://ej2.syncfusion.com/demos/src/schedule/images/newyear.svg' />";
  }
  return '';
};

var scheduleObj = new ej.schedule.Schedule({
  width: '100%',
  height: '550px',
  views: ['Day', 'Week', 'TimelineWeek', 'Month'],
  cssClass: 'schedule-cell-template',
  cellTemplate: '${if(type === "workCells")}<div class="templatewrap">${getWorkCellText(data.date)}</div>${/if}${if(type === "monthCells")}<div class="templatewrap">${getMonthCellText(data.date)}</div>${/if}',
  selectedDate: new Date(2017, 11, 16)
});
scheduleObj.appendTo('#Schedule');

Using renderCell event

An alternative to cellTemplate is the renderCell event, which can also be used to customize the cells with appropriate images or formatted text values.

var scheduleObj= new ej.schedule.Schedule({
    height: '550px',
    selectedDate: new Date(2018, 1, 14),
    currentView: 'Month',
    views: ['Day','Week', 'Month'],
    renderCell: function(args) {
        if (args.elementType == 'workCells' || args.elementType == 'monthCells') {
            var weekEnds = [0, 6];
            if (weekEnds.indexOf((args.date).getDay()) >= 0) {
                var ele = ej.base.createElement('div', {
                    innerHTML: "<img src='https://ej2.syncfusion.com/demos/src/schedule/images/newyear.svg' />",
                    className: 'templatewrap'
                });
                (args.element).appendChild(ele);
            }
        }
    },
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

You can customize cells such as work cells, month cells, all-day cells, header cells, resource header cells using renderCell event by checking the elementType option within the event. You can check elementType with any of the following.

Element type Description
dateHeader triggers on header cell rendering.
monthDay triggers on header cell in month view rendering.
resourceHeader triggers on resource header cell rendering.
alldayCells triggers on all day cell rendering.
emptyCells triggers on empty cell rendering on header bar.
resourceGroupCells triggers on rendering of work cells for parent resource.
workCells triggers on work cell rendering.
monthCells triggers on month cell rendering.
majorSlot triggers on major time slot cell rendering.
minorSlot triggers on minor time slot cell rendering.
weekNumberCell triggers on cell displaying week number.

Setting cell dimensions in all views

Customize the height and width of Scheduler cells to increase or reduce their size using the cssClass property, which overrides the default CSS applied on cells.

var scheduleObj = new ej.schedule.Schedule({
    width: '100%', height: '550px',
    views: ['Day', 'Week', 'WorkWeek', 'Month'],
    selectedDate: new Date(2018, 1, 15),
    cssClass: 'schedule-cell-dimension',
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

Check for cell availability

You can check whether the given time range slots are available for event creation or already occupied by other events using the isSlotAvailable method. In the following code example, if a specific time slot already contains an appointment, then no more appointments can be added to that cell.

Note: The isSlotAvailable is centered around verifying appointments within the present view’s date range. Yet, it does not encompass an evaluation of availability for recurrence occurrences that fall beyond this particular date range.

Customizing cell header in month view

The month header of each date cell in the month view can be customized using the cellHeaderTemplate option which accepts the string or HTMLElement. The corresponding date can be accessed with the template.

let instance = new ej.base.Internationalization();
window.getDate = date => {
  return instance.formatDate(date, { skeleton: "Ed" });
};
let scheduleObj = new ej.schedule.Schedule({
  width: "100%",
  height: "550px",
  views: ["Month"],
  cssClass: "schedule-cell-header-template",
  cellHeaderTemplate:
    '<div class="cell-header-wrap">${getDate(data.date)}</div>'
});
scheduleObj.appendTo("#Schedule");

Customizing the minimum and maximum date values

Providing the minDate and maxDate property with some date values, allows the Scheduler to set the minimum and maximum date range. The Scheduler date that lies beyond this minimum and maximum date range will be in a disabled state so that the date navigation will be blocked beyond the specified date range.

let scheduleObj = new ej.schedule.Schedule({
  width: "100%",
  height: "550px",
  views: ["Day", "Week", "Month", "Agenda", "Year"],
  selectedDate: new Date(2018, 1, 17),
  minDate: new Date(2017, 4, 17),
  maxDate: new Date(2018, 5, 17)
});
scheduleObj.appendTo("#Schedule");

By default, the minDate property value is set to new Date(1900, 0, 1) and maxDate property value is set to new Date(2099, 11, 31). The user can also set the customized minDate and maxDate property values.

Customizing the weekend cells background color

You can customize the background color of weekend cells by utilizing the renderCell event and checking the elementType option within the event.

renderCell: function (args) {
    if (args.elementType == "workCells") {
        // To change the color of weekend columns in week view
        if (args.date) {
            if (args.date.getDay() === 6) {
                (args.element).style.background = '#ffdea2';
            }
            if (args.date.getDay() === 0) {
                (args.element).style.background = '#ffdea2';
            }
        }
    }
}

And, the background color for weekend cells in the Month view through the cssClass property, which overrides the default CSS applied on cells.

.schedule-cell-customization.e-schedule .e-month-view .e-work-cells:not(.e-work-days) {
    background-color: #f08080;
}
var scheduleObj = new ej.schedule.Schedule({
    height: '550px',
    selectedDate: new Date(2018, 1, 14),
    currentView: 'Month',
    views: ['Day', 'Week', 'Month'],
    cssClass: 'schedule-cell-customization',
    renderCell: function (args) {
        if (args.elementType == "workCells") {
            // To change the color of weekend columns in week view
            if (args.date) {
                if (args.date.getDay() === 6) {
                    (args.element).style.background = '#ffdea2';
                }
                if (args.date.getDay() === 0) {
                    (args.element).style.background = '#ffdea2';
                }
            }
        }
    }
});
scheduleObj.appendTo('#Schedule');
