Remarks
We recommend using the UIElement focus routed events instead of FocusManager events whenever possible.
FocusNavigationDirection.Previous and FocusNavigationDirection.Next cannot be used with FindNextElementOptions. Only FocusNavigationDirection.Up, FocusNavigationDirection.Down, FocusNavigationDirection.Left, or FocusNavigationDirection.Right are valid.
UIElement focus events bubble up to the FocusManager in the following order:
- UIElement.LosingFocus/FocusManager.LosingFocus
- UIElement.GettingFocus/FocusManager.GettingFocus
- UIElement.LostFocus routed event is raised by the element that lost focus and the event bubbles up
- FocusManager.LostFocus is raised (even if the routed event is marked handled)
- UIElement.GotFocus routed event is raised by the element that received focus and the event bubbles up
- FocusManager.GotFocus is raised (even if the routed event is marked handled)
