C# EventTrigger RouteEvent未使用自定义事件触发

我试图在触发自定义路由事件（由我定义）时触发故事板播放。该事件称为CustomTest，在MyControl中定义

虽然正在触发事件，但触发器未播放情节提要

XAML:

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:gear="clr-namespace:GearWPF"
    x:Class="GearWPF.MyControl"
    x:Name="UserControl">

...

    <Grid x:Name="LayoutRoot" Background="#00000000">
        <Grid.Triggers>
            <EventTrigger RoutedEvent="gear:MyControl.CustomTest"> <!-- My custom event. -->
                <BeginStoryboard Storyboard="{StaticResource MyStoryBoard}"/>
            </EventTrigger>
        </Grid.Triggers>
    </Grid>

namespace GearWPF
{
    /// <summary>
    /// Interaction logic for MyControl.xaml
    /// </summary>
    public partial class MyControl: UserControl
    {

        // Create a custom routed event by first registering a RoutedEventID 
        // This event uses the bubbling routing strategy 
        public static readonly RoutedEvent CustomTestEvent = EventManager.RegisterRoutedEvent("CustomTest", RoutingStrategy.Bubbling, typeof(RoutedEventHandler), typeof(MyControl));

        // Provide CLR accessors for the event 
        public event RoutedEventHandler CustomTest
        {
            add { AddHandler(CustomTestEvent, value); }
            remove { RemoveHandler(CustomTestEvent, value); }
        }

        public MyControl()
        {
            this.InitializeComponent();
        }

        public void RaiseMyEvent()
        {
            RoutedEventArgs newEventArgs = new RoutedEventArgs(CustomTestEvent);
            RaiseEvent(newEventArgs);
        }
    }
}

...

C#：

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:gear="clr-namespace:GearWPF"
    x:Class="GearWPF.MyControl"
    x:Name="UserControl">

...

    <Grid x:Name="LayoutRoot" Background="#00000000">
        <Grid.Triggers>
            <EventTrigger RoutedEvent="gear:MyControl.CustomTest"> <!-- My custom event. -->
                <BeginStoryboard Storyboard="{StaticResource MyStoryBoard}"/>
            </EventTrigger>
        </Grid.Triggers>
    </Grid>

namespace GearWPF
{
    /// <summary>
    /// Interaction logic for MyControl.xaml
    /// </summary>
    public partial class MyControl: UserControl
    {

        // Create a custom routed event by first registering a RoutedEventID 
        // This event uses the bubbling routing strategy 
        public static readonly RoutedEvent CustomTestEvent = EventManager.RegisterRoutedEvent("CustomTest", RoutingStrategy.Bubbling, typeof(RoutedEventHandler), typeof(MyControl));

        // Provide CLR accessors for the event 
        public event RoutedEventHandler CustomTest
        {
            add { AddHandler(CustomTestEvent, value); }
            remove { RemoveHandler(CustomTestEvent, value); }
        }

        public MyControl()
        {
            this.InitializeComponent();
        }

        public void RaiseMyEvent()
        {
            RoutedEventArgs newEventArgs = new RoutedEventArgs(CustomTestEvent);
            RaiseEvent(newEventArgs);
        }
    }
}

wpf
{
/// 
///MyControl.xaml的交互逻辑
/// 
公共部分类MyControl:UserControl
{
//通过首先注册RoutedEventID创建自定义路由事件
//此事件使用冒泡路由策略
公共静态只读RoutedEvent CustomTestEvent=EventManager.RegisterRoutedEvent（“CustomTest”，RoutingStrategy.Bubbling，typeof（RoutedEventHandler），typeof（MyControl））；
//为事件提供CLR访问器
公共事件路由EventHandler自定义测试
{
添加{AddHandler（CustomTestEvent，value）；}
删除{RemoveHandler（CustomTestEvent，value）；}
}
公共MyControl（）
{
this.InitializeComponent（）；
}
公共无效的RaiseMyEvent（）
{
RoutedEventTargets newEventArgs=新RoutedEventTargets（CustomTestEvent）；
RaiseEvent（newEventArgs）；
}
}
}

我已经验证了RaiseMyEvent在我期望的时候被调用。使用Snoop，我可以看到事件一直在我的控制之下（处理为“False”）。但是，触发器实际上并没有启动故事板

我还将触发器更改为使用现有事件，当我这样做时，故事板将被触发。这让我相信这是我的路由事件CustomTest特有的东西

    <Grid x:Name="LayoutRoot" Background="#00000000">
        <Grid.Triggers>
            <EventTrigger RoutedEvent="Mouse.MouseEnter"> <!-- This works! -->
                <BeginStoryboard Storyboard="{StaticResource MyStoryBoard}"/>
            </EventTrigger>
        </Grid.Triggers>
    </Grid>

问题在于事件的级别太高。我将它发送到我的CustomControl，但我真正想做的是将它发送到CustomControl中的网格（因为事件只在根和源之间进行）

我在main window.xaml.cs中有自己的RouteEvent，并且我的EventTrigger没有启动。你的回答帮助了我，因为我把它放在了我的格子里，太低了，无法参加比赛！
