UIElement.GettingFocus Event

Definition

Occurs before a UIElement receives focus. This event is raised synchronously to ensure focus isn't moved while the event is bubbling.

Equivalent WinUI event: Microsoft.UI.Xaml.UIElement.GettingFocus.

// Register
event_token GettingFocus(TypedEventHandler<UIElement, GettingFocusEventArgs const &> const& handler) const;

// Revoke with event_token
void GettingFocus(event_token const* cookie) const;

// Revoke with event_revoker
GettingFocus_revoker GettingFocus(auto_revoke_t, TypedEventHandler<UIElement, GettingFocusEventArgs const &> const& handler) const;
public event TypedEventHandler<UIElement,GettingFocusEventArgs> GettingFocus;
function onGettingFocus(eventArgs) { /* Your code */ }
uIElement.addEventListener("gettingfocus", onGettingFocus);
uIElement.removeEventListener("gettingfocus", onGettingFocus);
- or -
uIElement.ongettingfocus = onGettingFocus;

Remarks

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 get focus when another control loses 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.

GettingFocus is a routed event. For more info on the routed event concept, see Events and routed events overview.
