Wpf用户控件的多个实例都使用相同的路由事件

public static readonly RoutedEvent MyCustomEvent = EventManager.RegisterRoutedEvent(
    "MyCustom", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyUserControl));

public event RoutedEventHandler MyCustom
{
    add { AddHandler(MyCustomEvent, value); }
    remove { RemoveHandler(MyCustomEvent, value); }
}

<UserControl x:Class="MyNamespace.MyUserControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:MyNamespace">
    <Grid>
        <!-- 用户控件的其他内容 -->
        
        <Button Content="Click Me" Click="Button_Click"/>
    </Grid>
    <UserControl.Triggers>
        <EventTrigger RoutedEvent="local:MyUserControl.MyCustom">
            <BeginStoryboard>
                <!-- 添加触发事件时的动画或其他操作 -->
            </BeginStoryboard>
        </EventTrigger>
    </UserControl.Triggers>
</UserControl>

private void Button_Click(object sender, RoutedEventArgs e)
{
    RoutedEventArgs args = new RoutedEventArgs(MyUserControl.MyCustomEvent);
    RaiseEvent(args);
}
