リストコレクションを作成し、それをデータグリッドに正常にバインドしたアプリケーションを作成しています。私が抱えている問題は、ユーザーがデータグリッドに変更を加えた後に [保存] ボタンをクリックしたときに、データグリッドからデータを取得し、それを使用して同じリスト コレクションの要素を形成することです。前もって感謝します。
XAML を以下に示します。
<Grid Background="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" AlternatingRowBackground="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"/>
</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>
以下はコードビハインドです。

InitializeComponent();
gridBeveragesAndJuices.ItemsSource = Source8;
