How to disable TextBlock?

This would be the proper way to do it with a TextBlock i think:

<TextBlock Text="Lorem ipsum dolor sit">
    <TextBlock.Style>
        <Style TargetType="{x:Type TextBlock}">
            <Style.Triggers>
                <Trigger Property="IsEnabled" Value="False">
                    <Setter Property="Foreground"
                            Value="{StaticResource {x:Static SystemColors.GrayTextBrushKey}}"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </TextBlock.Style>
</TextBlock>
