Override listviewitem background

Hi,

I'm trying to overwrite the listviewitem background color based on a property. It works but only when the item is not selected or mouse hovered. How can I fix it so the background color is always blue in my case when IsMarked property is true?

<ListView.ItemContainerStyle>
    <Style BasedOn="{StaticResource {x:Static themes:SharedResourceKeys.ListViewItemStyleKey}}" TargetType="{x:Type ListViewItem}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding Path=IsMarked}" Value="True">
                <Setter Property="Background" Value="{DynamicResource BlueBrush}" />
            </DataTrigger>
        </Style.Triggers>
    </Style>
</ListView.ItemContainerStyle>
