	You could intercept the Delete command instead of showing confirmation dialog in the NodeDeleting handler: Code CommandManager.AddPreviewCanExecuteHandler(diagram, CanDelete); void CanDelete(object sender, CanExecuteRoutedEventArgs e) { if (e.Command == ApplicationCommands.Delete) { if (MessageBox.Show("you sure ...?", "...", MessageBoxButton.YesNo) == MessageBoxResult.No) { e.Handled = true; e.CanExecute = false; } } } I hope that helps, Stoyan
