推荐答案

事件添加到您的用户控件像下面的代码，它会看起来像正常事件

Add event to your UserControl like code below and it will appears like normal event

    public partial class UserControl1 : UserControl
    {
       public delegate void ValueChangedEventHandler(object sender, EventArgs e);

       public event ValueChangedEventHandler ValueChanged;

       public UserControl1()
       {
           // Required to initialize variables
           InitializeComponent();
       }

       private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
       {
          if (ValueChanged != null)
          {
              ValueChanged(this, EventArgs.Empty);
          }
       }
   }

然后，只需订阅它

   private void UserControl1_ValueChanged(object sender, System.EventArgs e)
    {
        // TODO: Add event handler implementation here.
    }
