This class should be used only if you want to assign topics to UI elements in custom controls. If you need to handle UI elements inside custom controls, you have to create your own UIElementResolver object and override its virtual methods. Namely, when you override the UIElementResolver.GetUIElementInfo method, you need to create a UIElementInfo object and set its Name and Parent properties.
