Description Rolf Bjarne Kvinge [MSFT] 2013-02-27 07:26:59 UTC
It is currently not possible to style a custom subclass differently than the bound base class.

This is because the Appearance method is static, and the base class cannot know if the Appearance property was called on from a derived class or not.

One possibility is to introduce a method allowing you to specify the subclass:

public static UISlider.UISliderAppearance GetAppearanceForSubclass (Type subclass)
{
}

See this for context (and an ugly workaround): http://forums.xamarin.com/discussion/1552/uiappearance-on-a-subclass-affects-the-base-class

Note that the final solution is to do this:

UICustomClass.GetAppearance<UICustomClass>.Property = ...
