Extended WPF toolkit DoubleUpDown IsEnabled trigger changing background not working

Question

I am using an extended WPF control, which is DoubleUpDown. For this control a have defined a style and within it a trigger for IsEnabled property.

<Style TargetType="{x:Type extToolkit:DoubleUpDown}">
    <Style.Triggers>
        <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Background" Value="Pink"/>
        </Trigger>
    </Style.Triggers>
</Style>

For IsEnabled property I am using a binding from the ViewModel.

The problem is that when the control IsEnabled property is False the background is not all filled with pink, the pink color appears only between Up and Down buttons (See image).

How can I resolv this in order to fill all the control with the new pink color? Thank you for your help.
