Olá!
Você já tentou o evento CurrentChanged do ListBox.Items?
Segue um exemplo:
public Window4()
{
InitializeComponent();
this.lstBox.Items.CurrentChanged += new EventHandler(Items_CurrentChanged);
List<Person> personList = new List<Person>();
personList.Add(new Person() { Name = "Anderson" });this.lstBox.ItemsSource = personList;
}
void Items_CurrentChanged(object sender, EventArgs e)
{
// aqui vc implementa o codigo q será executado quando alterar
}Anderson
