问题 I'm trying to create an "overlap" effect (for lack of a better term). There will be a splitter that when moved, exposes a different view of two similar images (e.g. between colored and grayscale). I plan on using CustomGridSplitter from WinRTXAMLToolkit (due to WinRT's lack of a splitter).

问题 I'm searching for a way to find out which style resources a control uses. I.e. I'm currently trying to change the Brushes of the back Button in my app. Confusingly these brushes are partly located under the ResourceKey s AppBarItemPointerOverForegroundThemeBrush (etc.) instead of BackButtonPointerOverForegroundThemeBrush (which doesn't seem to change anything - side question: what's this resource for?).
