Question

I have an application that’s been running happily on windows 7 and below targeting the .net 4 framework.
If the application is now installed in windows 8 (Running .net 4.5 but still targeting .net 4) it shows a blue background for a selected item in a listbox or combobox and a white background for a focused item. Is there anyway to remove this?
I’m using the following in my XAML to set the style in question which seemed to resolve the issue before windows 8.

<ListBox.ItemContainerStyle>
                <Style TargetType="{x:Type ListBoxItem}">
                    <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
                    <Style.Resources>
                        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
                        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent"/>
                    </Style.Resources>
                </Style>
            </ListBox.ItemContainerStyle>

I forgot to come back with how I solved this…. Turns out that all you need to do it create a blank Item Container Style and assign it to your listbox/combobox etc…. You can use this as well as keeping the current style you may be using such as ListBox Style=”{StaticResource CurrentStyle}” ItemContainerStyle=”{StaticResource BlankListBoxContainerStyle}” /> Where BlankListBoxContainerStyle would be something like…..

<Style x:Key="BlankListBoxContainerStyle" TargetType="{x:Type ListBoxItem}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListBoxItem}">
                <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="FocusVisualStyle"
            Value="{x:Null}"/>
</Style>
