Control.FocusEngaged Event

Definition

Namespace:

Microsoft.UI.Xaml.Controls

Occurs as focus is constrained to the control when the user presses the A/Select button on a game controller.

// Register
event_token FocusEngaged(TypedEventHandler<Control, FocusEngagedEventArgs const&> const& handler) const;

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

// Revoke with event_revoker
Control::FocusEngaged_revoker FocusEngaged(auto_revoke_t, TypedEventHandler<Control, FocusEngagedEventArgs const&> const& handler) const;

public event TypedEventHandler<Control,FocusEngagedEventArgs> FocusEngaged;

function onFocusEngaged(eventArgs) { /* Your code */ }
control.addEventListener("focusengaged", onFocusEngaged);
control.removeEventListener("focusengaged", onFocusEngaged);
- or -
control.onfocusengaged = onFocusEngaged;

Public Custom Event FocusEngaged As TypedEventHandler(Of Control, FocusEngagedEventArgs) 

<control FocusEngaged="eventhandler"/>

Event Type

TypedEventHandler<Control,FocusEngagedEventArgs>

Remarks

When the IsFocusEngagementEnabled property is set to true, it marks the control as requiring focus engagement. This means that the user must press the A/Select button to "engage" the control and interact with it. When they are finished, they can press the B/Back button to disengage the control and navigate away from it.

Focus engagement makes it easier to use a game controller to interact with an app. Setting focus engagement does not affect keyboard or other input devices. For more info, see Focus engagement.
