The corresponding bubbling event is GotKeyboardFocus.
Override OnPreviewGotKeyboardFocus to implement class handling for this event in derived classes.
Because this event uses tunneling routing, the element that has focus might be a child element instead of the element where the event handler is actually attached. Check the Source in the event data to determine the actual element that has focus.
This event creates an alias for the Keyboard::PreviewGotKeyboardFocus attached event for this class, so that PreviewGotKeyboardFocus is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the PreviewGotKeyboardFocus event are attached to the underlying Keyboard::PreviewGotKeyboardFocus attached event and receive the same event data instance.
