How to: Cancel item selection

In this example, the NavBarViewBase.ItemSelecting event is handled, to invoke a confirmation dialog allowing the selection of a specific item ('Private') to be canceled.

private void navBar_ItemSelecting(object sender, NavBarItemSelectingEventArgs e){
    if (e.NewItem.Content.ToString() == "Private"){
        MessageBoxResult result = MessageBox.Show("Are you sure to select the 'Private' item?", "Confirm Dialog", MessageBoxButton.YesNo);
        e.Cancel = (result == MessageBoxResult.No);
    }
}
