Understand generic. XAML and themes

The name "Generic. XAML" is not accidental.
As described above, you may be impulsive to generic. the style code in XAML is cut out, pasted to any place that can be found by our control, and then generic. XAML deletes or changes it to a more elegant name. If you are lucky, this is feasible, because the control will look up the style from the bottom up (page, app, theme, but now you have made a potential mistake: You have not provided the default style for the control. the default style here is actually "the style used when the default topic is found for the control or not ". this involves theme related topics in WPF. If you are interested, refer to the msdn SDK.
