State persistence in Angular Schedule component

11 Jul 20242 minutes to read

State persistence allowed Scheduler to retain the currentView, selectedDate and Scroll position values in the localStorage for state maintenance even if the browser is refreshed or if you move to the next page within the browser. This action is handled through the enablePersistence property which is set to false by default. When it is set to true, currentView, selectedDate and Scroll position values of the scheduler component will be retained even after refreshing the page.

Note: Scheduler id is essential to set state persistence.

The following sample demonstrates how to set state persistence of the Scheduler component.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ScheduleModule } from '@syncfusion/ej2-angular-schedule'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { DayService, WeekService, WorkWeekService, MonthService, AgendaService, MonthAgendaService} from '@syncfusion/ej2-angular-schedule'



import { Component } from '@angular/core';
import { EventSettingsModel, TimeScaleModel } from '@syncfusion/ej2-angular-schedule';
import { scheduleData } from './datasource';

@Component({
imports: [
        
        ScheduleModule,
        ButtonModule
    ],

providers: [DayService, 
                WeekService, 
                WorkWeekService, 
                MonthService,
                AgendaService,
                MonthAgendaService],
standalone: true,
  selector: 'app-root',
  // specifies the template string for the Schedule component
  template: `<ejs-schedule id="schedule" width='100%' height='550px' [selectedDate]="selectedDate" [eventSettings]="eventSettings" [enablePersistence]="enablePersistence"> </ejs-schedule>`
})
export class AppComponent {
    public selectedDate: Date = new Date(2018, 1, 15);
    public eventSettings: EventSettingsModel = { dataSource: scheduleData };
    public enablePersistence: Boolean = true;
 }

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
