Hi schinnasamy1,

For now The ‘XamDataTree’ doesn’t have ‘DeleteNode Event’. But in your case you can use ‘ObservableCollection’ and receive its event ‘CollectionChanged’ which occurs when an item is added, removed, changed, moved, or the entire list is refreshed.

 I.e:

    var data = new ObservableCollection<TreeNode>();

    data.CollectionChanged += ContentCollectionChanged;

    public void ContentCollectionChanged(object sender, NotifyCollectionChangedEventArgs e) { //...}
