### 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/services/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
|
|
);
|
|
}
|
|
|
|
}
|
|
```
