WPF的DataTrigger绑定自身属性

<DataTrigger Binding="{Binding RelativeSource={RelativeSource self},Path=IfVertical}" Value="true">
	<Setter TargetName="PART_Stack" Property="Orientation" Value="Vertical"/>
</DataTrigger>

Binding="{Binding RelativeSource={RelativeSource self},Path=IfVertical}"

RelativeSource={RelativeSource self} 这句话就是绑定当前自身的属性,Path可以指定要绑定的属性名称
