Changing the Foreground colour of a contentpresenter in a listbox

Question

I have created the following style for a listbox that will have an image displayed next to some text:

<Style x:Key="ImageListBoxStyle" TargetType="{x:Type ListBox}">
    <Setter Property="SnapsToDevicePixels" Value="true"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>
    <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>
    <Setter Property="ScrollViewer.CanContentScroll" Value="True"/>
    <Setter Property="ItemContainerStyle">
        <Setter.Value>
            <!-- Simple ListBoxItem - This is used for each Item in a ListBox. The item's content is placed in the ContentPresenter -->
            <Style TargetType="{x:Type ListBoxItem}">
                <Setter Property="SnapsToDevicePixels" Value="true"/>
                <Setter Property="OverridesDefaultStyle" Value="true"/>
                <Setter Property="VerticalContentAlignment" Value="Center"/>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type ListBoxItem}">
                            <Grid SnapsToDevicePixels="true">
                                <Border x:Name="Border">
                                    <Grid Height="40">
                                        <Grid.ColumnDefinitions>
                                            <ColumnDefinition Width="Auto"/>
                                            <ColumnDefinition Width="*"/>
                                        </Grid.ColumnDefinitions>
                                        <Image

                                            Width="30"

    </Setter>
</Style>

I have to use the contentpresenter as I am filtering what is displayed (text wise) using the DisplayMemberPath of the ListBox itself.

All I want to do is set the FontWeight to Bold and the Foreground to White when an item is selected in the ListBox.

Has anyone encountered a problem like this? I have looked at some related questions but people have been able to use a TextBlock to get around their issues I can't unfortunately.

Any info ppl can give will be appreciated.

Cheers

Answer 1

It's all ok, I have managed to answer this question myself, I was trying to modify the foreground/fontweight of the contentpresenter which doesn't contain a definition for foreground/fontweight all i simply needed to do was this:

<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Foreground" Value="White"/>

i.e. remove the:

TargetName="DisplayText"
