Routed Events – Bubbling
Because I sometimes forget the syntax, a have here a quick bubbling routed event for WPF:
For you have to register the event. Then you have to create the poperty that adds and removed the handlers.
// Register the event
public static readonly RoutedEvent CloseEvent =
EventManager.RegisterRoutedEvent("Close", RoutingStrategy.Bubble, typeof(RoutedEventHandler),
typeof(CustomPopupControl));
// Provide CLR accessors for the event
public event RoutedEventHandler Close
{
add { AddHandler(CloseEvent, value); }
remove { RemoveHandler(CloseEvent, value); }
}
To manualy raise the event:
RoutedEventArgs args = new RoutedEventArgs(CloseEvent); RaiseEvent(args);
To listen for the event:
CustomPopupControl popup = new CustomerPopupControl(); popup.Close += new RoutedEventHandler(popup_Closed);
