    Hi Faris,

    In order to add a confirmation dialog before deleting a node, use the DialogService to dynamically create a dialog box during the delete event. For example:

    constructor( private dialogService: DialogService ) {}
    deleteEvent() {
      const dialog: DialogRef ={
        title: 'Please confirm',
        content: 'Are you sure you want to delete?',
        actions: [
          { text: 'No' },
          { text: 'Yes', primary: true }
        width: 450,
        height: 200,
        minWidth: 250
      dialog.result.subscribe((result) => {
        if (result instanceof DialogCloseResult) {
        } else {
          console.log('action', result);
        this.result = JSON.stringify(result);

    If the above solution does not work, could you please respond with your code or a StackBlitz example? I will further help you.

    Please give it a try and let me know if it helps.
