        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="20" />
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>
        <GroupBox Grid.Column="1" Header="A 1" HorizontalAlignment="Left" VerticalAlignment="Top">
            <StackPanel Orientation="Vertical">
                //GroupBox A
                //GroupBox B
                <StackPanel Orientation="Horizontal">
                    <GroupBox Header="C" Margin="0, 10, 0, 0" Width="600">
                        <Grid Margin="5, 0, 5, 0">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="120" />
                                <ColumnDefinition Width="105" />
                                <ColumnDefinition Width="35" />
                                <ColumnDefinition Width="*" />
                                <ColumnDefinition Width="120" />
                                <ColumnDefinition Width="105" />
                                <ColumnDefinition Width="35" />
                            </Grid.ColumnDefinitions>

                            <Grid.RowDefinitions>

                            </Grid.RowDefinitions>
