C# 行编辑结束和数据网格更新

我有WPF数据网格；当我使用RowEditEnding事件更新数据库时，它无法正常工作。 1.我在分配ID的代码中输入新的值，当我返回网格时，我看不到我的ID，只看到我键入的值。（如果关闭应用程序，数据将丢失） 2.当我再次双击datagrid并保留行中的所有内容时，数据将更新并保存在DB中

我用的方法对吗

以下是代码：

    <Window.Resources>
        <local:ManageOrdersDataSet x:Key="manageOrdersDataSet"/>
        <CollectionViewSource x:Key="customerViewSource" Source="{Binding Customer, Source={StaticResource manageOrdersDataSet}}"/>
    </Window.Resources>

<Grid DataContext="{StaticResource customerViewSource}">

                    <DataGrid x:Name="customerDataGrid" RowDetailsVisibilityMode="VisibleWhenSelected" Margin="0,0,-0.2,0.4" ItemsSource="{Binding}" EnableRowVirtualization="True" AutoGenerateColumns="False" RowEditEnding="customerDataGrid_RowEditEnding">
                        <DataGrid.Columns>
                            <DataGridTextColumn x:Name="iDColumn" Width="10" Header="ID" Binding="{Binding ID,  Mode=TwoWay, NotifyOnTargetUpdated=True, NotifyOnSourceUpdated=True, UpdateSourceTrigger=PropertyChanged}"/>
                            <DataGridTextColumn x:Name="nameColumn" Width="*" Header="Name" Binding="{Binding Name, Mode=TwoWay, NotifyOnTargetUpdated=True, NotifyOnSourceUpdated=True, UpdateSourceTrigger=PropertyChanged}"/>
                            <DataGridTextColumn x:Name="addressColumn" Width="*" Header="Address" Binding="{Binding Address,  Mode=TwoWay, NotifyOnTargetUpdated=True, NotifyOnSourceUpdated=True, UpdateSourceTrigger=PropertyChanged}"/>
                        </DataGrid.Columns>
                    </DataGrid>
                </Grid>

我找到了解决办法。 我无法很好地解释它，但显然，当eventRowEditEnding新数据行被认为没有值或没有更改时。 所以我决定调用事件处理程序

以下是步骤

将事件处理程序添加到已加载的Windows\u

manageOrdersDataSet.Customer.RowChanged+=新的DataRowChangeEventHandler（行\u已更改）； manageOrdersDataSet.Customer.RowDeleted+=新的DataRowChangeEventHandler（行\u已更改）

实现事件处理程序

公共无效行\u已更改（对象发送方、DataRowChangeEventArgs e） {

}

OrderManager.ManageOrdersDataSet manageOrdersDataSet;
        OrderManager.ManageOrdersDataSetTableAdapters.CustomerTableAdapter manageOrdersDataSetCustomerTableAdapter;
        System.Windows.Data.CollectionViewSource customerViewSource;

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {

            manageOrdersDataSet = ((OrderManager.ManageOrdersDataSet)(this.FindResource("manageOrdersDataSet")));
            // Load data into the table Customer. You can modify this code as needed.
             manageOrdersDataSetCustomerTableAdapter = new OrderManager.ManageOrdersDataSetTableAdapters.CustomerTableAdapter();
            manageOrdersDataSetCustomerTableAdapter.Fill(manageOrdersDataSet.Customer);
            customerViewSource = ((System.Windows.Data.CollectionViewSource)(this.FindResource("customerViewSource")));
            customerViewSource.View.MoveCurrentToFirst();

        }
 private void customerDataGrid_RowEditEnding(object sender, DataGridRowEditEndingEventArgs e)
        {
 if (rowView != null)
            {

                ManageOrdersDataSet.CustomerRow row = rowView.Row as ManageOrdersDataSet.CustomerRow;

                if (row.IsNull("Name"))
                {
                    row["Name"] = "Defailt";
                }
                if (row.IsNull("Address"))
                {
                    row["Address"] = "Address Def";
                }
                if (row.IsNull("ID"))
                {
                    row["ID"] = Guid.NewGuid();
                }
   this.manageOrdersDataSetCustomerTableAdapter.Update(row);
            }
           }

    try
    {
        this.manageOrdersDataSetCustomerTableAdapter.Update(manageOrdersDataSet.Customer);
    }
    catch
    {
        // do something
    }
