M:Microsoft.UI.Xaml.Input.LosingFocusEventArgs.TryCancel |
winrt method |
Attempts to cancel the ongoing focus action.
true
if the focus action is canceled; otherwise, false
.
You should call this method instead of setting the Cancel property.
The GotFocus routed event is raised on an element after it receives focus, while the LostFocus routed event is raised on an element after it loses focus.
The GettingFocus and LosingFocus routed events occur before the focus change takes place, which enables your application to modify or cancel the focus change behavior.
GettingFocus and LosingFocus are raised synchronously, while GotFocus and LostFocus are raised asynchronously. For example, if your app calls the Focus method of a control, GettingFocus
is raised during the call, but GotFocus
is raised after the call completes.
If focus is moved while these events are still bubbling, an exception is thrown.
