Display multiple colors in single event in Angular Schedule component

19 Sep 20245 minutes to read

In Scheduler we can display the multiple colors within a single event. This can be achieved by using the template option available within the eventSettings property. Here, we’ve used SubCount as an additional field. The SubCount field contains the background color and height values. Based on these values, events will be divided into different colors.

app.component.ts

import { Component, ViewEncapsulation } from '@angular/core';

import { EventSettingsModel, DayService, WeekService, WorkWeekService, MonthService, AgendaService, ResizeService, DragAndDropService, ScheduleModule } from '@syncfusion/ej2-angular-schedule';
@Component({
  imports: [ScheduleModule, CommonModule ],

  styleUrls: ['./index.css'],

              <div class='template-wrap'>
                <ng-template ngFor let-item [ngForOf]="data.SubCount">
