windows - WPF ComboBox: background color when disabled

Question

I currently use this style for my ComboBox in WPF:

    <Style TargetType="ComboBox">
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Background" Value="#303030"/>
        <Setter Property="BorderBrush" Value="#000000"/>
    </Style>

How can I change it to specify the background color when the ComboBox is disabled?

<Style TargetType="ComboBox">

    <Setter Property="Background" Value="#303030"/>
    <Setter Property="BorderBrush" Value="#000000"/>
    <Style.Triggers>
        <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Background" Value="#101010"/>
        </Trigger>
    </Style.Triggers>
</Style>
