Close md-dialog inside it's component.ts

I have a md-dialog component - DialogComponent - which i open from sibling component - SiblingComponent - and i want to close it in dialog.component.ts after some actions.

DialogComponent basically is a form with submit button, submitting form takes me to dialog.component.ts function where i'm doing some validation and sending data to service.

After validation passes and data is sent i want to make some timeout and then automatically close dial window, but i dont know how to run something like md-dialog-close in dialog.component.ts

You can inject an MdDialogRef into the dialog component class, and use that to close it. Example:

export class DialogComponent {

    constructor(private dialogRef: MdDialogRef<DialogComponent >) { }
   
    someAction() {
        // do your thing here
        this.dialogRef.close(); // <- this closes the dialog. 
        // You can also wrap it in setTimeout() if you want
    }
}

Edit 2025

import { MatDialogRef } from '@angular/material/dialog';

export class DialogComponent {
  constructor(private dialogRef: MatDialogRef<DialogComponent>) {}

  someAction() {
    this.dialogRef.close();
  }
}
