JavaScript/jQuery Scheduler - Customize Appointment Tooltip
jQuery
When a user clicks an appointment, the Scheduler shows a tooltip that can be customized. Combine HTML markup for tooltips with DOM methods. To apply this markup, use the appointmentTooltipTemplate callback function as shown in the following code:
JavaScript
$(() => {
const scheduler = $('#schedulerContainer').dxScheduler({
appointmentTooltipTemplate(data, cell) {
const tooltip = $('<div class="dx-tooltip-appointment-item">');
// NOTE: You can use data.appointmentData.resouceId to obtain resource color
const markerColor = '#337ab7';
const markerBody = $('<div class="dx-tooltip-appointment-item-marker-body">').css('background', markerColor);
const marker = $('<div class="dx-tooltip-appointment-item-marker">').append(markerBody);
const content = $('<div class="dx-tooltip-appointment-item-content">')
.append($('<div class="dx-tooltip-appointment-item-content-subject">').text(data.appointmentData.text))
.append($('<div class="dx-tooltip-appointment-item-content-date">').text(data.appointmentData.startDate));
tooltip.append(marker);
tooltip.append(content);
const isAppointmentDisabled = data.appointmentData.disabled;
const isDeleteAllowed = (scheduler.option('editing') && scheduler.option('editing.allowDeleting') === true)
|| scheduler.option('editing') === true;
if (!isAppointmentDisabled && isDeleteAllowed) {
const buttonContainer = $('<div class="dx-tooltip-appointment-item-delete-button-container">');
const button = $('<div class="dx-tooltip-appointment-item-delete-button">').dxButton({
icon: 'trash',
stylingMode: 'text',
onClick(e) {
scheduler.deleteAppointment(data.appointmentData);
e.event.stopPropagation();
scheduler.hideAppointmentTooltip();
}
});
buttonContainer.append(button);
tooltip.append(buttonContainer);
}
return tooltip;
},
}).dxScheduler('instance');
});Angular
When a user clicks an appointment, the Scheduler shows a tooltip that can be customized. The following code shows how to use dxTemplate to define templates for tooltips:
app.component.html
app.components.ts
tooltip.component.html
tooltip.components.ts
<dx-scheduler
#targetScheduler
appointmentTooltipTemplate="appointmentTooltipTemplate"
>
<ng-container *dxTemplate="let data of 'appointmentTooltipTemplate'">
<!-- NOTE: You can use data.appointmentData.resouceId to obtain resource color -->
<Tooltip
[appointmentData]="data.appointmentData"
[isDeleteButtonExist]="isDeleteButtonExist(data)"
[markerColor]="#337ab7"
(onDeleteButtonClick)="onDeleteButtonClick($event, data.appointmentData)"
></Tooltip>
</ng-container>
</dx-scheduler>
export class AppComponent {
@ViewChild('targetScheduler', { static: true })
scheduler: DxSchedulerComponent;
constructor(private service: Service) {}
onDeleteButtonClick(e: ClickEvent, appointmentData: dxSchedulerAppointment): void {
this.scheduler.instance.deleteAppointment(appointmentData);
e.event.stopPropagation();
this.scheduler.instance.hideAppointmentTooltip();
}
isDeleteButtonExist({ appointmentData }: { appointmentData: dxSchedulerAppointment}): boolean {
const schedulerInstance = this.scheduler.instance;
const isAppointmentDisabled = appointmentData.disabled;
const isDeleteAllowed = (schedulerInstance.option('editing') && schedulerInstance.option('editing.allowDeleting') === true)
|| schedulerInstance.option('editing') === true;
return !isAppointmentDisabled && isDeleteAllowed;
}
}

When a user clicks an appointment, the Scheduler shows a tooltip that can be customized. The following code shows how to define a rendering function for tooltips:
App.js
