### How to show a notification message for bad permission

You can show a notification error when the user doesn't have the right permission to perform
the action. The component emits a `permissionEvent` when the user does not have delete permission.
You can subscribe to this event from your component and use the 
[Notification service](../core/notification.service.md) to show a message.

```html
<adf-upload-button
    [rootFolderId]="currentFolderId"
    (permissionEvent)="onUploadPermissionFailed($event)">
</adf-upload-button>
```

```ts
export class MyComponent {

    onUploadPermissionFailed(event: any) {
        this.notificationService.openSnackMessage(
            `you don't have the ${event.permission} permission to ${event.action} the ${event.type} `, 4000
        );
    }

}
```
