C# wpf 使用DataTrigger Binding到enum的Storyboard 多段动画,显示出现错误

Question

我希望可以根据一个enum：DoorState 属性的改变来改变界面上的动画,

    public enum DoorState 
    {
        Unknow,
        Close,
        Half_Open,
        Open,
    }

当doorState=open时，door会自当前位置平滑移动到上方;half_open时,door会自当前位置平滑移动到中间;close时，door 会自当前位置平滑移动到下方

但是我在使用以下代码实现功能时，发现有些状态变化会导致Rectange对象恢复到最原始的位置再移动到目标位置，如：从half_open 到close，并且三个DataTrigger 的上下位置改变会导致错误现象发生条件的改变，如：close到open。
想请问怎么才能仅依靠xaml文件实现这样的动画？
如果需要借助cs文件，又该怎么实现？

<Rectangle x:Name="door" Height="100"  Width="20" Stroke="Black" Fill="LightGray"  VerticalAlignment="Top" HorizontalAlignment="Left">
            <Rectangle.Style>
                <Style TargetType="Rectangle">
                    <Setter Property="Margin" Value="315,150,0,0"></Setter>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Path=DataContext.DoorState,RelativeSource={RelativeSource Self}}" 
                                     Value="{x:Static DataClass:DoorState.Close}">
                            <DataTrigger.EnterActions>
                                
                                <BeginStoryboard x:Name="CloseDoor">
                                    <Storyboard FillBehavior="HoldEnd">
                                        <ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="Margin">

                                        </ThicknessAnimationUsingKeyFrames>
