<Border Width="130" Height="70">
    <Border.Triggers>
        <DataTrigger Binding="{Binding Path=CurrentStatus}" Value="0">
            <Setter Property="Style" Value="{StaticResource ResourceKey=ListBoxItemBorder}"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding Path=CurrentStatus}" Value="200">
            <Setter Property="Style" Value="{StaticResource ResourceKey=ListBoxItemBorderInactive}"/>
        </DataTrigger>
    </Border.Triggers>
</Border>

Error at object '4_T' in markup file

<Style TargetType="Border" x:Key="BorderStyle">
    <!-- These setters are the same as your normal style when none of your triggers are true -->
    <Setter Property="BorderBrush" Value="Black" />
    <Style.Triggers>
        <DataTrigger Binding="{Binding Path=CurrentStatus}" Value="0">
            <!-- These setters are the same as your ListBoxItemBorder style -->
            <Setter Property="BorderBrush" Value="Green" />
