Activate an automatic clicking action in the ng-datepicker

Currently, I am facing a challenge while working on an Angular 2 project using Typescript. The calendar I have created is only displayed after a click event, but I would like it to appear on the page as soon as it loads without requiring any user interaction. As I am still learning Typescript, I am unable to achieve this functionality.

Below is the code snippet:

<ng-datepicker [ngModel]="startDatePicker"></ng-datepicker>

In my TypeScript file, I have the following code:

startDatePicker: Date = moment().subtract(1, 'day').toDate();

If you need additional context, please refer to the following screenshots:

HTML

<ng-datepicker #reference [ngModel]="startDatePicker"></ng-datepicker>

Typescript

import { ViewChild } from '@angular/core';
/*some Different Code*/
ngOnInit() {
@ViewChild('reference')
private datepicker: ElementRef;

this.datepicker.nativeElement.click();
}

To access the component from the template, assign it an id and invoke the toggle method on it.

Here's a basic illustration:

The main component:

@Component({
  selector: 'my-app',
  template: `
    <div>
      <h2>Hello {{name}}</h2>
      <toggle-comp #toggleComp></toggle-comp>
    </div>
  `,
})
export class App implements AfterViewInit {
  name:string;

  @ViewChild('toggleComp') public testComp: TestComp;

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

  ngAfterViewInit() {
    setInterval(() => {
      this.testComp.toggleState();

    }, 1000);
  }
}

The child component (in this case, the datepicker).

@Component({
  selector: 'toggle-comp',
  template `<div>{{toggle}}</div>`
})
export class TestComp {
 public toggle= false;

  constructor() {}

  public toggleState() {
    this.toggle = !this.toggle;
  }
}

In the scenario of dealing with a datepicker, you would assign the # id to the ng-datepicker element.

<ng-datepicker #datePicker [ngModel]="startDatePicker"></ng-datepicker>

Then reference it in the component using @ViewChild('datePicker').
