示例1: GetRoutedEvent
private RoutedEvent GetRoutedEvent(UIElement element, out UIElement targetObject)
{
if (string.IsNullOrEmpty(TargetName))
{
targetObject = element;
}
else
{
// Search the element in "normal" name scope and in the dynamic structure via the FindElement method
// I think this is more than WPF does. It makes it possible to find elements instantiated
// by a template, for example.
targetObject = (element.FindElementInNamescope(TargetName) ??
element.FindElement(new NameMatcher(TargetName))) as UIElement;
if (targetObject == null)
return null;
}
var routedEvent = _routedEvent;
if (routedEvent == null)
{
// the routed event is not set already, so we try to get it from the targetObject
return EventManager.GetRoutedEventForOwner(targetObject.GetType(), Event, true);
}
return routedEvent;
}示例2: FindPropertyDescriptor
protected bool FindPropertyDescriptor(UIElement element,
out IDataDescriptor propertyDescriptor, out DependencyObject targetObject)

// I think this is more than WPF does. It makes it possible to find elements instantiated
// by a template, for example.
targetObject = element.FindElementInNamescope(targetName) ??
element.FindElement(new NameMatcher(targetName));
if (targetObject == null)
return false;
