Angular Scheduler Methods
addAppointment(appointment)
The appointment; should have the same structure as objects in the dataSource.
beginUpdate()
Prevents the UI component from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

defaultOptions(rule)
defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the Scheduler UI component in an application executed on the desktop.
- import Scheduler, { Properties } from "devextreme/ui/scheduler";
- // ...
- export class AppComponent {
- constructor () {
- Scheduler.defaultOptions<Properties>({
- device: { deviceType: "desktop" },
- options: {
- // Here go the Scheduler properties
- }
- });
- }
- }
deleteAppointment(appointment)
An appointment object from the dataSource.
If you delete a recurring appointment from the data source, all its occurrences are also deleted from the timetable:
- <dx-button
- text="Delete"
- (onClick)="deleteAppointment()">
- </dx-button>
- <dx-scheduler
- [(dataSource)]="appointments"
- [currentDate]="currentDate">
- </dx-scheduler>
- import { Component, ViewChild } from "@angular/core";
- import { Appointment, Service } from './app.service';
- import { DxSchedulerComponent } from "devextreme-angular";
- @Component({
- selector: 'app-root',
- templateUrl: './app.component.html',
- styleUrls: ['./app.component.css']
- })
- export class AppComponent {
- @ViewChild(DxSchedulerComponent, { static: false }) scheduler: DxSchedulerComponent;
- // Prior to Angular 8
- // @ViewChild(DxSchedulerComponent) scheduler: DxSchedulerComponent;
- currentDate: Date = new Date(2018, 4, 25);
- appointments: Appointment[];
- constructor(service: Service) {
- this.appointments = service.getAppointments();
- }
- deleteAppointment() {
- this.scheduler.instance.deleteAppointment(this.appointments[0]);
- }
- }
- import { Injectable } from "@angular/core";
- export class Appointment {
- text: string;
- startDate: Date;
- endDate: Date;
- recurrenceRule?: string;
- }
- let appointments: Appointment[] = [{
- text: "Website Re-Design Plan",
- startDate: new Date(2018, 4, 25, 9, 0),
- endDate: new Date(2018, 4, 25, 9, 30),
- recurrenceRule: "FREQ=DAILY;COUNT=10"
- },
- // ...
- ];
- @Injectable()
- export class Service {
- getAppointments(): Appointment[] {
- return appointments;
- }
- }
- import { BrowserModule } from '@angular/platform-browser';
- import { NgModule } from '@angular/core';
- import { AppComponent } from './app.component';
- import {
- DxButtonModule,
- DxSchedulerModule
- } from "devextreme-angular";
- import { Service } from './app.service';
- @NgModule({
- declarations: [
- AppComponent
- ],
- imports: [
- BrowserModule,
- DxButtonModule,
- DxSchedulerModule
- ],
- providers: [
- Service
- ],
- bootstrap: [AppComponent]
- })
- export class AppModule { }

getInstance(element)
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the Scheduler instance found in an element with the myScheduler
ID:
- // Modular approach
- import Scheduler from "devextreme/ui/scheduler";
- ...
- let element = document.getElementById("myScheduler");
- let instance = Scheduler.getInstance(element) as Scheduler;
- // Non-modular approach
- let element = document.getElementById("myScheduler");
- let instance = DevExpress.ui.dxScheduler.getInstance(element);

on(eventName, eventHandler)
Use this method to subscribe to one of the events listed in the Events section.
See Also

scrollTo(date, group, allDay)
Scrolls the current view to a specified position. Available for all views except "agenda". You should specify the height property to use this method.
If appointments are grouped by resources, specifies a group ID (optional).
If true, scrolls the view to the all-day panel of the specified group. Applies only if the all-day panel is visible.
The following example shows how to use this method:
- // Scroll to January 14, 2021
- scrollTo(new Date(2021, 0, 14));
- // Scroll to the second group at 5:30 p.m. on January 14, 2021
- scrollTo(new Date(2021, 0, 14, 17, 30), {groupId: 2})
- // Scroll to the all-day panel of the second group
- scrollTo(new Date(2021, 0, 14, 17, 30), {groupId: 2}, true);
See Also
scrollToTime(hours, minutes, date)
Use the scrollTo(dategroupallDay) method instead.
If the specified date is outside the current date range, the method scrolls the view to the specified time.
