Disable click outside of angular material dialog area to close the dialog (With Angular Version 4.0+)

How to Disable Clicking Outside the Angular Material Dialog in Angular Version 4.0+

Are you tired of users accidentally closing your Angular Material dialogs by clicking outside the dialog area? It can be frustrating, especially when you have important information or forms inside the dialog. But fear not! In this guide, I'll show you a simple way to disable the click outside feature and keep your dialogs open until you're ready to close them.

The Problem

As mentioned by our fellow developer, By default, Angular Material dialogs close automatically when the user clicks outside of the dialog area. While this behavior is helpful in some cases, there are situations where we want more control over the dialog's close action. In our password reset page, for example, we want to ensure that the user doesn't accidentally close the dialog while in the middle of resetting their password.

The Solution 🛠️

To disable the click outside feature of an Angular Material dialog, you need to make use of the disableClose property provided by the MatDialogConfig object. Here's how you can implement it:

1. Import the MatDialogConfig from @angular/material/dialog at the top of your component file, where you're using the dialog.

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

1. When opening the dialog, create an instance of MatDialogConfig and set the disableClose property to true.

const dialogConfig = new MatDialogConfig();
dialogConfig.disableClose = true;

// Then, open the dialog using the config
this.dialog.open(YourDialogComponent, dialogConfig);

By setting disableClose to true, you're effectively disabling the click outside feature of the dialog, meaning it won't close when the user clicks outside.

Example Usage

Let's see this solution in action with a simple example. Imagine we have a button that opens a dialog to display a message. We want to prevent the user from closing the dialog by clicking outside.

import { Component } from '@angular/core';
import { MatDialog, MatDialogConfig } from '@angular/material/dialog';

@Component({
  selector: 'app-dialog-button',
  template: `
    <button mat-raised-button color="primary" (click)="openDialog()">Open Dialog</button>
  `
})
export class DialogButtonComponent {
  constructor(private dialog: MatDialog) {}

  openDialog(): void {
    const dialogConfig = new MatDialogConfig();
    dialogConfig.disableClose = true;

    this.dialog.open(DialogComponent, dialogConfig);
  }
}

In the example above, we have a component with a button that triggers the opening of a dialog. The disableClose property is set to true, which prevents the dialog from closing when the user clicks outside of it.

You're in Control! 🚀

By following this simple solution, you're now in full control of when your Angular Material dialogs close. No more accidental closures!

Now go ahead and implement this solution in your Angular 4+ project to create unclosable dialogs that keep your users focused and engaged.
