How to tell which WPF UserControl was clicked?

I have a bunch of user controls with buttons on them stored in a listbox. Right now they all pass their button events to a main script and that prints "A button was clicked", it would be better though if it printed "Button D was clicked" as I need to store exactly which buttons were clicked in an array.

The sender parameter in the event call refers to the sending button.

private void btn1_Click(object sender, RoutedEventArgs e)
{
   Button button = (Button)sender;
}

This might work if the first one does not:

private void btn1_Click(object sender, RoutedEventArgs e)
{
  Button button = (Button)e.OriginalSource;
}

here's a more generic approach if you only want the listboxitem

private void btn1_Click(object sender, RoutedEventArgs e)
{
    object context = (e.OriginalSource as FrameworkElement).DataContext;
    var lbi = lb.ItemContainerGenerator.ContainerFromItem(context) as ListBoxItem;
}

Couldn't you use the CommandParameter of the button and reference that.
