Occurs when this element loses logical focus.
public:
event System::Windows::RoutedEventHandler ^ LostFocus;public event System.Windows.RoutedEventHandler LostFocus;member this.LostFocus : System.Windows.RoutedEventHandler Public Custom Event LostFocus As RoutedEventHandler Event Type
Remarks
Logical focus differs from keyboard focus if focus is deliberately forced away by using a method call but the previous keyboard focus exists in a different scope. In this scenario, keyboard focus remains where it is, and the element where a Focus method is called still gets logical focus.
A more precise interpretation of this event is that it is raised when the value of the IsFocused property of an element in the route changes from true to false.
Because this event uses bubbling routing, the element that loses 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 gained focus.
