Open/Close sidenav from another component

I used @Input() inputSideNav: MatSideNav in parent\ another component to pass the sideNav object as target property from child component. It works as expected. By the way, I liked the service implementation by @Eldho :)

1. It is simple to plugin in your current implementation
2. It is scalable to as many sideNav or other UI controls passed as reference into the component definition
3. No cluttering in code and plain as it looks.
4. Vote up if you get what we mean :)

Child.component.html

<app-layout-header [inputSideNav]="sideNav"></app-layout-header>
<mat-sidenav-container>
  <mat-sidenav #sideNav (click)="sideNav.toggle()" mode="side">
    <a routerLink="/">List Products</a>
  </mat-sidenav>
  <mat-sidenav-content>
    <router-outlet></router-outlet>
  </mat-sidenav-content>
</mat-sidenav-container>

layout-header.component.html

<section>
  <mat-toolbar>
    <span (click)="inputSideNav.toggle()">Menu</span>
  </mat-toolbar>
</section>

layout-header.component.ts

import { Component, OnInit, Input } from '@angular/core';
import { MatSidenav } from '@angular/material';

@Component({
  selector: 'app-layout-header',
  templateUrl: './layout-header.component.html',
  styleUrls: ['./layout-header.component.css']
})
export class LayoutHeaderComponent implements OnInit {
  @Input() inputSideNav: MatSidenav;

  constructor() { }

  ngOnInit() {
  }
}

I had the same problem using. I resolved it like this.

SidenavService

import { Injectable } from '@angular/core';
import { MatSidenav } from '@angular/material';

@Injectable()
export class SidenavService {
    private sidenav: MatSidenav;


    public setSidenav(sidenav: MatSidenav) {
        this.sidenav = sidenav;
    }

    public open() {
        return this.sidenav.open();
    }


    public close() {
        return this.sidenav.close();
    }

    public toggle(): void {
    this.sidenav.toggle();
   }

Your Component

constructor(
private sidenav: SidenavService) { }

toggleRightSidenav() {
   this.sidenav.toggle();
}

Bind your html toggle() based on your requirement.

App component.

@ViewChild('sidenav') public sidenav: MatSidenav;

constructor(private sidenavService: SidenavService) {
}

ngAfterViewInit(): void {
  this.sidenavService.setSidenav(this.sidenav);
}

App Module

providers: [YourServices , SidenavService],

Angular 9+ Update

Per this answer on SO, "Components can no longer be imported through @angular/material. Use the individual secondary entry-points, such as @angular/material/button." As such, make sure to import MatSidenav like so:

import { MatSidenav } from '@angular/material/sidenav';
