Vue Scheduler - Delete Appointments

User Interaction

After a user clicks an appointment, the Scheduler displays a tooltip with two buttons. To delete an appointment, a user clicks the button with a bucket icon. Note that the appointment will be deleted from the data source.

If a user deletes a recurring appointment, the Scheduler displays a dialog where users can choose between deleting the current appointment and deleting the entire series of recurring appointments. If you do not want this dialog to appear, choose the edit mode beforehand using the recurrenceEditMode property.

HTML
TypeScript
  • <dx-scheduler ...
  • recurrenceEditMode="occurrence"> <!-- or 'series' | 'dialog' -->
  • </dx-scheduler>
  • import { DxSchedulerModule } from "devextreme-angular";
  • // ...
  • export class AppComponent {
  • // ...
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxSchedulerModule
  • ],
  • // ...
  • })

To prevent a user from deleting an appointment, set the editing.allowDeleting property to false.

HTML
TypeScript
  • <dx-scheduler ... >
  • <dxo-editing [allowDeleting]="false"></dxo-editing>
  • </dx-scheduler>
  • import { DxSchedulerModule } from "devextreme-angular";
  • // ...
  • export class AppComponent {
  • // ...
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxSchedulerModule
  • ],
  • // ...
  • })

API

To delete an appointment, call the deleteAppointment(appointment) method. This method deletes an appointment defined by the parameter from the data source.

HTML
TypeScript
  • <dx-scheduler
  • [(dataSource)]="appointments"
  • [currentDate]="currentDate">
  • </dx-scheduler>
  •  
  • <dx-button
  • text="Delete"
  • (onClick)="deleteAppointment()">
  • </dx-button>
  • import { ..., ViewChild } from "@angular/core";
  • import { DxButtonModule, DxSchedulerModule, DxSchedulerComponent } from "devextreme-angular";
  • // ...
  • export class AppComponent {
  • @ViewChild(DxSchedulerComponent, { static: false }) scheduler: DxSchedulerComponent;
  • // Prior to Angular 8
  • // @ViewChild(DxSchedulerComponent) scheduler: DxSchedulerComponent;
  • appointments = [{
  • text: "Website Re-Design Plan",
  • startDate: new Date("2016-04-25T09:00:00.000Z"),
  • endDate: new Date("2016-04-25T09:30:00.000Z")
  • },
  • // ...
  • ];
  • currentDate = new Date(2016, 4, 25);
  •  
  • deleteAppointment() {
  • this.scheduler.instance.deleteAppointment(this.appointments[0]);
  • }
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxSchedulerModule,
  • DxButtonModule
  • ],
  • // ...
  • })

Events

To execute certain commands before or after an appointment was deleted, handle the appointmentDeleting or appointmentDeleted event. If the event handling function is not going to be changed during the lifetime of the UI component, assign it to the corresponding onEventName property when you configure the UI component.

HTML
TypeScript
  • <dx-scheduler ...
  • (onAppointmentDeleting)="onAppointmentDeleting($event)"
  • (onAppointmentDeleted)="onAppointmentDeleted($event)">
  • </dx-scheduler>
  • import { DxSchedulerModule } from "devextreme-angular";
  • // ...
  • export class AppComponent {
  • onAppointmentDeleting (e) {
  • // Handler of the "appointmentDeleting" event
  • }
  •  
  • onAppointmentDeleted (e) {
  • // Handler of the "appointmentDeleted" event
  • }
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxSchedulerModule
  • ],
  • // ...
  • })
