Remove Control Highlight From ListBoxItems but not children controls

Question

I am using a ListBox to display a list of items: PictureOrders. I have applied a DataTemplate for the ListBox's Items.

I would like to style the list box so that the items are not highlighted when the mouse is over any of the items in the list box and so that the selected item in the list box is not highlighted either.

So, I used the following in the ListBox's resources:

  <ListBox.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"  />
            <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
   </ListBox.Resources>

However, now the ComboBoxes within the ListBox no longer have highlight colors which poses a bit of a problem.

I have the following classes:

Public Class PictureOrder
   Public Property OrderName As String
   Public Property NumberOfPictures As Integer
   Public Property QualityOfPictures As Integer
   Public Property Comments As String
End Class

Public Class PictureOrders
   Public Property PictureOrders As ObjectModel.ObservableCollection(Of PictureOrder)

   Public Sub New()
    PictureOrders = New ObjectModel.ObservableCollection(Of PictureOrder)
    For i As Integer = 1 To 11 '
        Dim picOrder As New PictureOrder With {.OrderName = String.Format("Picture Order # {0}", i.ToString),
                                               .NumberOfPictures = 50,
                                               .QualityOfPictures = 10,
                                               .Comments = String.Format("Picture Order # {0} Comments", i.ToString)}
        PictureOrders.Add(picOrder)
    Next
   End Sub
End Class

Here is my current XAML:

You can set the SolidColorBrush resources in a style that only targets ListBoxItem.

Since ComboBoxItem inherits from ListBoxItem, the ComboBox will still be affected though, so it's also necessary to create a style for ComboBoxItem to apply the default colors.

<ListBox.Resources>
    <Style TargetType="ListBoxItem">
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
        </Style.Resources>
    </Style>

    <Style TargetType="ComboBoxItem">
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="{x:Static SystemColors.HighlightColor}"/>
             <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{x:Static SystemColors.ControlColor}"/>
        </Style.Resources>
    </Style>
</ListBox.Resources>
