Windows runtime caliburn winrt usercontrol和捕获自定义事件

我制作了自己的滑块作为用户控件，带有一些自定义属性和一个自定义事件。一切正常，但最近我开始使用Caliburn Micro，我不知道如何捕获自定义事件

我以前用过：

<my:RadialSlider x:Name="slider" WedgeAngle="270" ..... AngleChanged="slider_AngleChanged" />

现在，在Caliburn项目中，我尝试：

<my:RadialSlider x:Name="slider" WedgeAngle="270" ..... cal:Message.Attach="[Event AngleChanged] = [Action slider_AngleChanged($eventArgs)]" />

但是，这不起作用

那么，如何捕捉这一事件呢

滑块UC代码隐藏：

public delegate void AngleChangedEventHandler(object sender, ValueChangedEventArgs e);

    public sealed partial class RadialSlider : UserControl
    {
public event AngleChangedEventHandler AngleChanged;

        private void OnAngleChanged(ValueChangedEventArgs e)
        {
            if (AngleChanged != null)
                AngleChanged(this, e);
        }

public static readonly DependencyProperty WedgeAngleProperty = DependencyProperty.Register("WedgeAngle", typeof(double), typeof(RadialSlider), new PropertyMetadata((double)270, new PropertyChangedCallback(OnPropertyWedgeAngleChanged)));
        public double WedgeAngle
        {
            get { return (double)this.GetValue(WedgeAngleProperty); }
            set { this.SetValue(WedgeAngleProperty, value); }
        }

private static void OnPropertyWedgeAngleChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
        {
            (sender as RadialSlider).UpdateControls();
            if (e.NewValue != e.OldValue)
            {
                (sender as RadialSlider).OnAngleChanged(new ValueChangedEventArgs((double)e.OldValue, (double)e.NewValue));
            }
        }

}您需要使用路由事件。这与事件如何在视觉树上冒泡以及Caliburn.Micro如何将自身连接到它们有关。任何技术中的控件或UI小部件都应该避免使用标准事件，使用Xaml作为一些非常时髦的功能（气泡上升/下降）。

正常，我将用示例更新帖子您的事件是RoutedEvent还是普通.NET事件？试着使用RoutedEvent或RoutedEvent，看看它是否有效，这可能是因为触发器假定事件是路由的。

public void slider_AngleChanged(object sender, ValueChangedEventArgs e)
    {
    .... something ....
    }

public delegate void AngleChangedEventHandler(object sender, ValueChangedEventArgs e);

    public sealed partial class RadialSlider : UserControl
    {
public event AngleChangedEventHandler AngleChanged;

        private void OnAngleChanged(ValueChangedEventArgs e)
        {
            if (AngleChanged != null)
                AngleChanged(this, e);
        }

public static readonly DependencyProperty WedgeAngleProperty = DependencyProperty.Register("WedgeAngle", typeof(double), typeof(RadialSlider), new PropertyMetadata((double)270, new PropertyChangedCallback(OnPropertyWedgeAngleChanged)));
        public double WedgeAngle
        {
            get { return (double)this.GetValue(WedgeAngleProperty); }
            set { this.SetValue(WedgeAngleProperty, value); }
        }

private static void OnPropertyWedgeAngleChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
        {
            (sender as RadialSlider).UpdateControls();
            if (e.NewValue != e.OldValue)
            {
                (sender as RadialSlider).OnAngleChanged(new ValueChangedEventArgs((double)e.OldValue, (double)e.NewValue));
            }
        }
