Occurs each time the inclinometer reports a new sensor reading.

Public Custom Event ReadingChanged As TypedEventHandler(Of Inclinometer, InclinometerReadingChangedEventArgs)

Event Type

TypedEventHandler<Inclinometer,InclinometerReadingChangedEventArgs>

Examples

The following example demonstrates how a UWP app built with C# and XAML registered its ReadingChanged event handler.

private void ScenarioEnable(object sender, RoutedEventArgs e)
{
    if (_inclinometer != null)
    {
        // Establish the report interval
        _inclinometer.ReportInterval = _desiredReportInterval;

        Window.Current.VisibilityChanged += new WindowVisibilityChangedEventHandler(VisibilityChanged);
        _inclinometer.ReadingChanged += new TypedEventHandler<Inclinometer, InclinometerReadingChangedEventArgs>(ReadingChanged);

        ScenarioEnableButton.IsEnabled = false;
        ScenarioDisableButton.IsEnabled = true;
    }
    else
    {
        rootPage.NotifyUser("No inclinometer found", NotifyType.StatusMessage);
    }
}

The following example shows the ReadingChanged event handler.

async private void ReadingChanged(object sender, InclinometerReadingChangedEventArgs e)
{
    await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
    {
        InclinometerReading reading = e.Reading;
        ScenarioOutput_X.Text = String.Format("{0,5:0.00}", reading.PitchDegrees);
        ScenarioOutput_Y.Text = String.Format("{0,5:0.00}", reading.RollDegrees);
        ScenarioOutput_Z.Text = String.Format("{0,5:0.00}", reading.YawDegrees);
    });
}

Remarks

Applications can set the frequency of this event by setting the ReportInterval property.
