Open PrimeNG calendar programmatically

Question

I'm using the PrimeNG components w/Angular 4 but I'm running into an issue - that is how do I display the calendar when my button is clicked?

See Plunker

@Component({
selector: 'my-app',
  template: `
    <div>
      <h2>Hello {{name}}</h2>
      <button pButton type="button" (click)="openCalendar($event)" label="Open Calendar"></button>
      <br/><br/>
      <p-calendar #calendar [(ngModel)]="value"></p-calendar>
    </div>
  `,
})
export class App {
  name: string;
  value: Date;

  @ViewChild('calendar')
  calendar: any;

  constructor() {
    this.name = `Angular! v${VERSION.full}`
  }

  openCalendar(event: any) {
    console.log(event);
  }
}

I have tried getting the template element reference using @ViewChild('calendar'). I have also tried applying focus using @ViewChild('calendar#inputfield') but that doesn't work.

Any idea how to click a button to programmatically open the calendar?

Answer 1

You can use showOverlay method on primeng calendar

openCalendar(event: any) {
  this.calendar.showOverlay(this.calendar.inputfieldViewChild.nativeElement);
  event.stopPropagation();
}
