DataGrid

I am creating an application in which I created a list collection and successfully binded bound it to a DataGrid. The problem I am having is to pull data back from the datagrid and use it to form the elements of the same list collection when a user clicks the SAVE button after making changes to the DataGrid.

Thanks in advance.

THS IS THE XAML This is the Xaml:

<grid removed="CornflowerBlue">
    <datagrid autogeneratecolumns="False" height="530" horizontalalignment="Left" margin="12,12,0,0" name="gridBeveragesAndJuices" verticalalignment="Top" width="573">
              HorizontalGridLinesBrush="Cyan" RowBackground="#FF12AD12" VerticalGridLinesBrush="Cyan" Foreground="Cyan" EnableColumnVirtualization="False" 
              EnableRowVirtualization="False" CanUserDeleteRows="True" CanUserAddRows="True" CanUserReorderColumns="False" CanUserResizeColumns="False" CanUserResizeRows="False" CanUserSortColumns="False" AlternatingRowremoved="DodgerBlue" FontSize="13">
        <datagrid.resources>
            <Style TargetType="{x:Type DataGridColumnHeader}">
                <setter property="Foreground" value="DodgerBlue" />
                <setter property="BorderBrush" value="Yellow" />
            </Style>
        </datagrid.resources>
        <datagrid.columns>
            <datagridtextcolumn width="287" header="                        ITEMS">
                       Binding="{Binding Path=ITEMS8, Mode=TwoWay, NotifyOnTargetUpdated=True}" x:Name="ItemsColumn" />
            <datagridtextcolumn width="286" header="                        PRICE">
                       Binding="{Binding Path=PRICE8, Mode=TwoWay, NotifyOnTargetUpdated=True}" x:Name="PriceColumn"/>
        </datagridtextcolumn></datagridtextcolumn></datagrid.columns>
    </datagrid>
    <Button Content="Cancel" Height="23" HorizontalAlignment="Left" Margin="67,578,0,0" Name="btnCancel" VerticalAlignment="Top" Width="75" />
    <Button Content="Save" Height="23" HorizontalAlignment="Left" Margin="256,578,0,0" Name="btnSave" VerticalAlignment="Top" Width="75" Click="btnSave_Click" />
    <Button Content="Exit" Height="23" HorizontalAlignment="Left" Margin="444,578,0,0" Name="btnExit" VerticalAlignment="Top" Width="75" />


</grid>

This is the code behind:

public partial class BeveragesAndJuices : Window
{
    public BeveragesAndJuices()
    {
        InitializeComponent();
        gridBeveragesAndJuices.ItemsSource = Source8;
    }

    public class Values8 
    {
        public string ITEMS8 { get; set; }
        public decimal PRICE8 { get; set; }
    }


    public List<values8> Source8 = new List<values8> 
    {
        new Values8(){ITEMS8 = "Lacasera ", PRICE8 = 290}, new Values8(){ITEMS8 = "Cran-Orange Chiller ", PRICE8 = 290}, new Values8(){ITEMS8 = "Festive Fruity Flavored Milk  ", PRICE8 = 290}, 
        new Values8(){ITEMS8 = "Homemade Iced Coffee ", PRICE8 = 290}, new Values8(){ITEMS8 ="Lemon Cucumber Seltzer " , PRICE8 = 290}, new Values8(){ITEMS8 = "Fizzy Water ", PRICE8 = 290},

        new Values8(){ITEMS8 ="anned Milo " , PRICE8 = 290}, new Values8(){ITEMS8 ="Viju Milk " , PRICE8 = 290}, new Values8(){ITEMS8 = "5 Alive ", PRICE8 = 290}, 
        new Values8(){ITEMS8 ="Cherry Vanilla Smoothie  " , PRICE8 = 290}, new Values8(){ITEMS8 = "Boysenberry-Banana Blast ", PRICE8 = 290}, new Values8(){ITEMS8 = "Vanilla Iced Mochaccino  ", PRICE8 = 290}, 
        new Values8(){ITEMS8 ="Choco-Nana Milk Mixer " , PRICE8 = 290}, new Values8(){ITEMS8 = "Fresh Fruit Pudding Milk Mixer ", PRICE8 = 290}, new Values8(){ITEMS8 ="Luscious Licuado  " , PRICE8 = 290}, 
        new Values8(){ITEMS8 = "Frosty Pine-Orange Yogurt Smoothie ", PRICE8 = 290}, new Values8(){ITEMS8 = "Mocha-ccino Freeze ", PRICE8 = 290}, new Values8(){ITEMS8 ="Lite Iced Mocha " , PRICE8 = 290},

    };

    private void btnSave_Click(object sender, RoutedEventArgs e)
    {
        //clear the elements of the source  
        Source8.Clear();

        //get the items on the datagrid and use them to form new elements of the 
        //Source8

        foreach(DataGridRow Row in gridBeveragesAndJuices)
        {
            //this where am stuck, foreach flags an error
            //that DataGridRow does not have a definition for GetEnumerator
        }
    }
