raising a custom routed event

[r0k3t]

Hi there,

well, it appears there are many things I don't understand! Can you imagine that? At any rate I am creating a custom routed event (for practice not a work thing or anything) and don't really seem to grasp how to cause the thing to fire or get raised. Let me show you the code and explain what I mean.

Here is the XAML

<Window x:Class="RoutedEventTestTwo.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:RoutedEventTestTwo"
    Title="Window1" Height="300" Width="300">
    <Grid> 
      <local:MyButton Width="200" Height="30" x:Name="myButton" Content="My Button" />
    </Grid>
</Window>

Now - Here is the code for the window

namespace RoutedEventTestTwo
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
            //myButton.MyClick += new RoutedEventHandler(myButton_MyClick);       
        }

        private void myButton_MyClick(object sender, RoutedEventArgs e)
        {

        }
      
    }
}

And here is the code for my "MyButton" class

namespace RoutedEventTestTwo
{
    public class MyButton:  Button
    {
        public static readonly RoutedEvent myClickEvent;

        static MyButton()
        {
            myClickEvent = EventManager.RegisterRoutedEvent("MyClick", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyButton));
            
        }

        public event RoutedEventHandler MyClick
        {
            add { AddHandler(myClickEvent, value); }
            remove { RemoveHandler(myClickEvent, value); }
        }

        protected override void OnClick()
        {
            RaiseMyClickEvnet();
        }

        void RaiseMyClickEvnet()
        {
            RoutedEventArgs routedEventArgs = new RoutedEventArgs(MyButton.myClickEvent);
            RaiseEvent(routedEventArgs);
        }


    }
}

The only way I can raise the event is to use the onclick method - I am trying to figure out a way around that? What if I didn't have an onlick? How would I capture and raise the event?

I keep seeing these blog posts that show you how to create the routed event using EventManager.RegisterRoutedEvent, and they tell you about creating the handler and called AddHanddler() and RemoveHandler() - that is the straight forward part (at least where I am concerned) they always seem to leave out just how to raise the event, even where they talk about it - they seem to show you the few lines of code where they create a new RoutedEventArgs but mysteriously always leave it out of context.

You can see that I tried

myButton.MyClick += new RoutedEventHandler(myButton_MyClick);

but of course that didn't work cause what is listening for it?

OK - As you can see - I am clearly missing something here... Anyone got any poiters? That would be great.

Thanks!

Is there no one that has anything to comment on this? Am I missing something so obvious?

Thanks
