自定义RoutedEvent作为EventTrigger

问题描述

我有自己的造型课

public sealed class MirrorTile : Shape

在这个课程中，我添加了事件

and in this class I added the event

public static readonly RoutedEvent SelectedEnterEvent = EventManager.RegisterRoutedEvent("SelectedEnter", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MirrorTile));

public event RoutedEventHandler SelectedEnter
{
    add
    {
        this.AddHandler(SelectedEnterEvent, value);
    }

    remove
    {
        this.RemoveHandler(SelectedEnterEvent, value);
    }
}

并希望以这种方式使用

<shapes:MirrorTile>
    <shapes:MirrorTile.Triggers>
        <EventTrigger RoutedEvent="SelectedEnter">
            <BeginStoryboard Storyboard="{StaticResource SelectShape}"/>
        </EventTrigger>
    </shapes:MirrorTile.Triggers>
</shapes:MirrorTile>

在启动后，我得到一个例外:{"RoutedEventConverter cannot convert from System.String."}

After starup I get the exception:{"RoutedEventConverter cannot convert from System.String."}

我在做什么错了，我该如何解决这个问题?

What I'm doing wrong and how can I fix this problem?

推荐答案

<EventTrigger RoutedEvent="shapes:MirrorTile.SelectedLeave">

名称空间也丢失了.
