Привязка WPF в XAML к C# в определении столбца сетки

Итак, я написал код Xaml, чтобы создать сетку данных с сеткой над ней, чтобы иметь несколько заголовков. Теперь я хочу динамически сгенерировать сетку, но я использовал привязки в свойствах WidthColumnDefenition ... И я понятия не имею, как преобразовать это в C#

Это то, что у меня есть в Xaml:

<StackPanel Grid.Row = "2" Margin = "0,30" x:Name = "print_content">

    <TextBlock x:Name = "txt_selected_class" Text = "KLASSE HIER" />

    <!--Here will the result come-->
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width = "{Binding ElementName=pos, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=Nr, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=pilot, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=pilot_club, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=pilot_license, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=navigator, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=navigator_club, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=navigator_license, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_1_tot_gtk, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_1_tot_timecontrol, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_1_tot_control, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_1_distance, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_2_tot_gtk, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_2_tot_timecontrol, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_2_tot_control, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=part_2_distance, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=end_tot_gtk, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=end_tot_dist, Path=ActualWidth, Mode=OneWay}"/>
            <ColumnDefinition Width = "{Binding ElementName=end_tot_points, Path=ActualWidth, Mode=OneWay}"/>
        </Grid.ColumnDefinitions>

Теперь это работает так, как должно, но в моем C# у меня есть следующее;

private void LayoutPartOne(string klasse)
{
    // Add the class name to the document
    TextBlock txt_selected_class = new TextBlock()
    {
        Text = klasse + "(" + inp_tour_part.Text + ")"
    };

    // Initiate the new grid
    Grid grid = new Grid();

    // Add al the column defenitions
    ColumnDefinition pos = new ColumnDefinition();
    pos.Width = 

}

pos.Width = дальше не заполняется, так как я совершенно не знаю, как добавить {Binding ElementName=pos, Path=ActualWidth, Mode=OneWay} из Xaml ... Есть идеи? Или решения для этого?
