XAML的DataGrid更新不更新數據庫

我想對RowEditEnding事件 DB名更新從XAML DataGrid的數據庫記錄：ManageOrders 表：客戶：ID（GUID），姓名（VARCHAR），地址（VARCHAR）數據庫設置爲：複製，如果新的數據集設置爲：不復制XAML的DataGrid更新不更新數據庫

如果我硬代碼中使用UPDATE和的ExecuteNonQuery我得到的結果，但是當我試圖使用的數據集/ dataTableAdapter.Update它不會更新我的查詢。請幫忙。注意我對WPF和C＃編程非常新穎。我花了一個星期的時間研究這個問題，找不到答案或者自己解決。

這裏是我的代碼

public partial class MainWindow : Window 
{ 
    public MainWindow() 
    { 
     InitializeComponent(); 
    } 


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

    private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 

     manageOrdersDataSet = ((SimpleData.ManageOrdersDataSet)(this.FindResource("manageOrdersDataSet"))); 
     // Load data into the table Customer. You can modify this code as needed. 
     manageOrdersDataSetCustomerTableAdapter = new SimpleData.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)   
{ 
    this.manageOrdersDataSetCustomerTableAdapter.Update(this.manageOrdersDataSet.Customer); 
     manageOrdersDataSet.AcceptChanges(); 

} 
}

這裏是我的XAML

我找到了答案，我的問題。當我創建我的數據庫我忘了設置PRIMARY KEY。我的意思是我沒有去的屬性和選擇的領域 - 主鍵（在MSSQL經理，表格的設計）沒有設置，Visual Studio中無法建立UPDATE命令正確

來驗證我去（右鍵點擊ON）表適配器 - >配置 - >提前選項，並檢查刷新數據表是否打開。

希望這將有助於某人某一天。
