Typescript - Angular: Pass data from Material Dialog to component, which didn't open the dialog

To pass data from a Material Dialog to a component that didn't open the dialog, you can achieve this by using a shared service. Here's how you can do it:

  1. Create a Shared Service: First, create a shared service that will be responsible for passing data between the dialog and the component.

    import { Injectable } from '@angular/core'; import { BehaviorSubject } from 'rxjs'; @Injectable({ providedIn: 'root' }) export class DialogService { private dataSubject = new BehaviorSubject<any>(null); data$ = this.dataSubject.asObservable(); setData(data: any) { this.dataSubject.next(data); } }

  2. Open the Material Dialog: In the component that opens the Material Dialog, inject the shared service and use it to pass data to the dialog.

    import { Component } from '@angular/core'; import { MatDialog } from '@angular/material/dialog'; import { DialogComponent } from './dialog/dialog.component'; import { DialogService } from './dialog.service'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor(private dialog: MatDialog, private dialogService: DialogService) {} openDialog(): void { const dialogRef = this.dialog.open(DialogComponent, { width: '250px' }); dialogRef.afterClosed().subscribe(result => { console.log('The dialog was closed'); }); this.dialogService.setData({ foo: 'bar' }); // Pass data to the dialog } }

  3. Receive Data in the Component: In the component that didn't open the dialog, inject the shared service and subscribe to the data observable to receive the data.

    import { Component, OnInit } from '@angular/core'; import { DialogService } from '../dialog.service'; @Component({ selector: 'app-other-component', templateUrl: './other-component.component.html', styleUrls: ['./other-component.component.css'] }) export class OtherComponentComponent implements OnInit { data: any; constructor(private dialogService: DialogService) {} ngOnInit(): void { this.dialogService.data$.subscribe(data => { this.data = data; console.log('Received data from dialog:', data); }); } }

  4. Access Data in the HTML: You can then access the data in the HTML template of the component using interpolation or other Angular techniques.

    <p>Data from dialog: {{ data | json }}</p>

By using a shared service, you can easily pass data between components, including from a Material Dialog to a component that didn't open the dialog.
