E:Windows.UI.Xaml.UIElement.LosingFocus |
winrt event |
Occurs before a UIElement loses focus. This event is raised synchronously to ensure focus isn't moved while the event is bubbling.
<uiElement LosingFocus="eventhandler"/>
We recommend using the UIElement focus routed events instead of FocusManager events whenever possible.
Only a single UI element at a time can have focus.
A control can lose focus when another control gets focus, the application view changes, the user switches applications, or the user interacts with the system such that the application is no longer in the foreground.
When programmatically navigating between elements, FocusNavigationDirection.Previous and FocusNavigationDirection.Next cannot be used with FindNextElementOptions. Only FocusNavigationDirection.Up, FocusNavigationDirection.Down, FocusNavigationDirection.Left, or FocusNavigationDirection.Right are valid.
LosingFocus is a routed event. For more info on the routed event concept, see Events and routed events overview.
