Your XAML is incorrect, but i guess you want to see this:

        Style st = new Style();
        DataTrigger tg = new DataTrigger()
        {
            Binding = new Binding("CustomerId"),
            Value = 1
        };            
        tg.Setters.Add(new Setter()
        {
            Property = Control.BackgroundProperty,
            Value = ColorConverter.ConvertFromString("Red")
        });
        st.Triggers.Add(tg);
