How can I know which VisualState of control already defined in XAML?
For example, WPF Button control has 2 VisualStateGroups by default. They are "CommonStates" and "FocusStates". The "CommonStates" contains 4 VisualState: "Normal", "MouseOver", "Pressed", "Disabled". These states already have default handlers so when the mouse over or pressed, Button's VisualState changes corresponding. Thank you for reading!
