Geolocator.StatusChanged Geolocator.StatusChanged Geolocator.StatusChanged Geolocator.StatusChanged Geolocator.StatusChanged Event


Raised when the ability of the Geolocator to provide updated location changes.

public : event TypedEventHandler<Geolocator, StatusChangedEventArgs> StatusChanged
// Register
event_token StatusChanged(TypedEventHandler<Geolocator, StatusChangedEventArgs> const& handler) const;

// Revoke with event_token
void StatusChanged(event_token const& cookie) const;

// Revoke with event_revoker
StatusChanged_revoker StatusChanged(auto_revoke_t, TypedEventHandler<Geolocator, StatusChangedEventArgs> const& handler) const;
public event TypedEventHandler<Geolocator, StatusChangedEventArgs> StatusChanged
Public Event StatusChanged As TypedEventHandler (Of Geolocator, StatusChangedEventArgs)
function onStatusChanged(eventArgs){/* Your code */}

geolocator.addEventListener("statuschanged", onStatusChanged);
geolocator.removeEventListener("statuschanged", onStatusChanged);


This code example demonstrates how the StatusChanged event is handled. The Geolocator object triggers the StatusChanged event to indicate that the user's location settings changed. That event passes the corresponding status via the argument's Status property (of type PositionStatus ). Note that this method is not called from the UI thread and the Dispatcher object invokes the UI changes. For more info, see Get current location.

using Windows.UI.Core;
async private void OnStatusChanged(Geolocator sender, StatusChangedEventArgs e)
    await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        // Show the location setting message only if status is disabled.
        LocationDisabledMessage.Visibility = Visibility.Collapsed;

        switch (e.Status)
            case PositionStatus.Ready:
                // Location platform is providing valid data.
                // notify user: Location platform is ready

            case PositionStatus.Initializing:
                // Location platform is attempting to acquire a fix. 
                // notify user: Location platform is attempting to obtain a position

            case PositionStatus.NoData:
                // Location platform could not obtain location data.
                // notify user: Not able to determine the location

            case PositionStatus.Disabled:
                // The permission to access location data is denied by the user or other policies.
                // notify user: Access to location is denied

                // Clear cached location data if any

            case PositionStatus.NotInitialized:
                // The location platform is not initialized. This indicates that the application 
                // has not made a request for location data.

                // notify user: No request for location is made yet

            case PositionStatus.NotAvailable:
                // The location platform is not available on this version of the OS.

                // notify user: Location is not available on this version of the OS

                // unknown result


You can access information about the event with the StatusChangedEventArgs object that is passed to your event handler.

When using a geofence, use the GeofenceMonitor 's StatusChanged event to monitor changes in location permissions instead of this event from the Geolocator class. A GeofenceMonitorStatus of Disabled is equivalent to a **Disabled **PositionStatus - both indicate that the app does not have permission to access location.
