Examples

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
                break;

            case PositionStatus.Initializing:
                // Location platform is attempting to acquire a fix. 

                // notify user: Location platform is attempting to obtain a position
                break;

            case PositionStatus.NoData:
                // Location platform could not obtain location data.

                // notify user: Not able to determine the location
                break;

            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
                break;

            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
                break;

            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
                break;

            default:
                // unknown case
                break;
        }
    });
}
