Почему не работает DataContext WPf

Есть такая разметка окна

<Window x:Class="NET03._1.AddWindowSensor"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        <ComboBox x:Name="SensorTypeComboBox" Grid.Row="0" Grid.Column="1" Height="20" Width="120" DataContext="{Binding Path=SensorType}" SelectedIndex="0" />

                    <Binding.ValidationRules>

            </TextBox.Text>
        </TextBox>

    </Grid>
</Window>

И ее код

 public partial class AddWindowSensor : Window,IAddWindowSensorView
    {
        private int _measuringInterval = 3;
        public AddWindowSensor()
        {
            InitializeComponent();
            this.SensorTypeComboBox.ItemsSource = Enum.GetValues(typeof(SensorType));
            this.DataContext = _measuringInterval;
        
            
        }

        public SensorType SensorType { get; set; }

        public int MeasuringInterval
        {
            get => _measuringInterval;
            set
            {
                if (_measuringInterval == 0)
                {
                    throw new ArgumentOutOfRangeException("Can't be less or equal 0");
                }

                _measuringInterval = value;
            }
        }

        public void ShowMessageError(string message)
        {
            MessageBox.Show(message);
        }

        public event EventHandler<EventArgs> AddNewSensor;
    }

Я уже все перебробовал но ничего не работает ни к свойству ни к полю. Что я делаю не так?
