How to update data from a DataSet?

My problem is that I can not update the data in my registry, when I modify a data and I give it to save, it generates the following error:

  

System.InvalidOperationException: 'Update requires UpdateCommand to be valid when the DataRow collection is passed with modified rows.'

Modify Data Window Code

private TElectronicaDataSet electronicaDataSet;
    private TElectronicaDataSetTableAdapters.ProductosTableAdapter 
     electronicaDataSetTableAdapter;
    private CollectionViewSource viewSource;
    public Modificar()
    {
        InitializeComponent();
    }

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        electronicaDataSet = ((VentaElectronica.TElectronicaDataSet)(this.FindResource("tElectronicaDataSet")));
        // Cargar datos en la tabla Productos. Puede modificar este código según sea necesario.
        electronicaDataSetTableAdapter = new VentaElectronica.TElectronicaDataSetTableAdapters.ProductosTableAdapter();
        electronicaDataSetTableAdapter.Fill(electronicaDataSet.Productos);
        viewSource = ((System.Windows.Data.CollectionViewSource)(this.FindResource("productosViewSource")));
        viewSource.View.MoveCurrentToFirst();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {

            electronicaDataSetTableAdapter.Update(electronicaDataSet);
            MessageBox.Show("Guardado");
