如何在枚举属性中使用DataTrigger？

<Window x:Class="WpfApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:WpfApp"
        Title="MainWindow" Height="450" Width="800">
    <Window.Resources>
        <local:EnumToBooleanConverter x:Key="EnumToBooleanConverter" />
    </Window.Resources>
    <Grid>
        <ComboBox x:Name="comboBox" SelectedItem="{Binding SelectedItem}">
            <ComboBox.ItemsSource>
                <x:Array Type="{x:Type local:EnumType}">
                    <local:EnumType.Value1 />
                    <local:EnumType.Value2 />
                    <local:EnumType.Value3 />
                </x:Array>
            </ComboBox.ItemsSource>
        </ComboBox>
        <TextBlock Text="Selected Value:">
            <TextBlock.Style>
                <Style TargetType="TextBlock">
                    <Setter Property="Foreground" Value="Black" />
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding SelectedItem, ElementName=comboBox, Converter={StaticResource EnumToBooleanConverter}, ConverterParameter={x:Type local:EnumType}}"
                                     Value="True">
                            <Setter Property="Foreground" Value="Red" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </TextBlock.Style>
        </TextBlock>
    </Grid>
</Window>
