Question

I have declared an event in my UserControl class Main:

public static readonly RoutedEvent CloseEvent = EventManager.RegisterRoutedEvent(
    "CloseClick", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(Main));
public event RoutedEventHandler CloseClick
{
    add { AddHandler(CloseEvent, value); }
    remove { RemoveHandler(CloseEvent, value); }
}

This code should be valid since I’ve used in other classes. The problem is when Im trying to listen to the event in another class.

UserControl content;
if (value == "main")
{
    content = new Main();
    content.CloseClick += new RoutedEventHandler(closeClick);
} else {
    ...
    ...
}
MasterPage.addContent(content);

I want “content” to be of any type derived from UserControl.
If I declare “content” as type “Main” the event is found but If its declared as the BaseClass “UserControl” everything but the event works. Am I missing something?

Thats how it should work right. I mean Main is the correct type for the source of that event and not UserControl (which can be anything).

If you want an event that is raised for any userControl then create a Attached Routed Events. They can be raised from any DependencyObject (i.e. Main or base UserControl or both).
