There has to be a way in the form it's on to say "Set the combo boxes to use TimerPickerComboStyle" ...

public static readonly DependencyProperty ComboBoxStyleProperty = DependencyProperty.Register(

public Style ComboBoxStyle

public override void OnApplyTemplate()

    var comboBox = GetTemplateChild("PART_FirstCombo") as ComboBox;
    if (comboBox != null)
    {
        comboBox.SetBinding(FrameworkElement.StyleProperty, 
            GetTimePickerBinding(ComboBoxStyleProperty));

<uc1:TimePicker
    ComboBoxStyle="{StaticResource TimePickerComboStyle}"
/>

<Style TargetType="{x:Type uc1:TimePicker}">
