events in custom control in wpf

Question

I've made this user control and it works well, I'm trying to covert it to a Custom Control, but I can't hook up my handler to those 3 events.
any help will be appreciated.

<Canvas x:Class="SMFU.UserControls.Public.MovableChildCanvas"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
        xmlns:local="clr-namespace:SMFU.UserControls.Public"
        mc:Ignorable="d" 

        Height="auto" Width="auto"

        Background="Transparent"
        MouseLeftButtonDown="canvas_MouseLeftButtonDown"
        MouseLeftButtonUp="canvas_MouseLeftButtonUp"
        MouseMove="canvas_MouseMove"  >
</Canvas>

You can declare and register routing events in your custom control, and override the event method:

class MyButton : Button
    {
        public static readonly RoutedEvent MyEventRoutedEvent =
        EventManager.RegisterRoutedEvent("MyEvent", RoutingStrategy.Bubble, typeof(EventHandler<MyEventRoutedEventArgs>), typeof(MyButton));
        //CLR
        public event RoutedEventHandler MyEvent
        {
            add { this.AddHandler(MyEventRoutedEvent, value); }
            remove { this.RemoveHandler(MyEventRoutedEvent, value); }
        }

        protected override void OnClick()
        {
            base.OnClick();

            MyEventRoutedEventArgs args = new MyEventRoutedEventArgs(MyEventRoutedEvent, this);
            args.ClickTime = DateTime.Now;
            this.RaiseEvent(args);
        }
    }

Declare the MyEventRoutedEventArgs:

 class MyEventRoutedEventArgs : RoutedEventArgs
    {
        public MyEventRoutedEventArgs(RoutedEvent routedEvent, object source) : base(routedEvent, source) { }

        public DateTime ClickTime { get; set; }
    }

Then you can use it in the control like local:MyEventRoutedEvent.MyEvent="Event_MyEvent"
