I had some trouble today getting the actual control that hosts data in a WPF listbox.  The magic class is ListBox.ItemContainerGenerator used like this:

MyStateObject current = this.myListBox.SelectedItem as MyStateObject;
ListBoxItem lbi = this.myListBox.ItemContainerGenerator.ContainerFromItem(current) as ListBoxItem;
lbi.Margin = new Thickness(10);
