TableAdapter不保存对SQL的更改表

Question

美好的一天！

我是C＃的新手。

我有数据集在Windows窗体中，我已经添加了一个记录数据集。然后我调用TableAdapter.Update（MyTable）（RowState处于增加模式）。进行了更改，我可以在绑定到SQL MyTable的DataGridView中看到它们。我可以关闭我的应用程序并重新开始，我会看到添加的记录。

private void button1_Click(object sender, EventArgs e) 
    { 
     DimaeSQLDS dsAddToDima = new DimaeSQLDS(); 

     using (DimaeSQLDSTableAdapters.OrganizationsTableAdapter orgAdapter = new DimaeSQLDSTableAdapters.OrganizationsTableAdapter()) 
     { 
      orgAdapter.Fill(dsAddToDima.Organizations); 
      DimaeSQLDS.OrganizationsRow organizationsRow = dsAddToDima.Organizations.NewOrganizationsRow(); 
      organizationsRow.Address = tbINN.Text; 
      organizationsRow.OrgName = tbOrgName.Text; 
      organizationsRow.UrFiz = 0; 
      dsAddToDima.Organizations.Rows.Add(organizationsRow); //adds row to DataSet  
      this.Validate(); 
      orgAdapter.Update(dsAddToDima.Organizations); 
     } 

     this.Close(); 
    } 

现在是我的问题：

我去服务器资源管理器 - > MyTable的（在这里我添加的记录） - >右键点击“显示表数据”，我看没有记录添加到桌子。然后我再次启动我的应用程序......在我查看MyTable之后，我新添加的记录被删除。

我无法理解这种魔法！请帮帮我！

!!!! UPDATE !!!!!

这是我的第一个形式。父窗体

namespace DimaeApplication 
{ 
    public partial class fOrganizations: Form 
    { 

     #region variables 
     fAddOrganization addOrganization; 
     fContainer container; 
     #endregion 

     public fOrganizations() 
     { 
      InitializeComponent(); 
     } 

     private void fOrganizations_Load(object sender, EventArgs e) 
     {    
      // TODO: This line of code loads data into the 'dimaeSQLDS.Organizations' table. You can move, or remove it, as needed. 
      this.organizationsTableAdapter.Fill(this.dimaeSQLDS.Organizations); 
     } 

     public void ReloadBindigs(object sender) 
     { 

      if (this.tbSearchOrganization.Text == string.Empty) 
       this.organizationsTableAdapter.Fill(this.dimaeSQLDS.Organizations); 
      else 
       try 
       { 
        string searchParam = "%" + this.tbSearchOrganization.Text + "%"; 
        this.organizationsTableAdapter.FillBy(this.dimaeSQLDS.Organizations, searchParam); 
       } 
       catch (System.Exception ex) 
       { 
        System.Windows.Forms.MessageBox.Show(ex.Message); 
       } 

     } 



     private void tsbCreateOrg_Click(object sender, EventArgs e) 
     { 
      if (addOrganization == null || addOrganization.IsDisposed) 
      { 

       addOrganization = new fAddOrganization(); 
       addOrganization.MdiParent = container ; 
       addOrganization.Show(); 
      } 
     } 

    } 
} 

我的第二形态。儿童。我在这里添加记录

namespace DimaeApplication 
{ 
    public partial class fAddOrganization : Form 
    { 
     public fAddOrganization() 
     { 
      InitializeComponent(); 
     } 

     private void button1_Click(object sender, EventArgs e) 
     { 
      DimaeSQLDS dsAddToDima = new DimaeSQLDS(); 

     using (DimaeSQLDSTableAdapters.OrganizationsTableAdapter orgAdapter = new DimaeSQLDSTableAdapters.OrganizationsTableAdapter()) 
     { 
      orgAdapter.Fill(dsAddToDima.Organizations); 
      DimaeSQLDS.OrganizationsRow organizationsRow = dsAddToDima.Organizations.NewOrganizationsRow(); 
      organizationsRow.Address = tbINN.Text; 
      organizationsRow.OrgName = tbOrgName.Text; 
      organizationsRow.UrFiz = 0; 
      dsAddToDima.Organizations.Rows.Add(organizationsRow); //adds row to DataSet  
      this.Validate(); 
      orgAdapter.Update(dsAddToDima.Organizations); 
     } 



      this.Close(); 
     } 

     private void fAddOrganization_FormClosed(object sender, FormClosedEventArgs e) 
     { 
      fOrganizations org = new fOrganizations();   
      org.ReloadBindigs(org); 
     }  
    } 
} 

如果您需要为每个表单生成代码，请告诉我。

谢谢你！

实际上，当您创建使用SQL CE数据库的项目时，它会在mydocuments和驱动器c上的项目文件夹中创建两个SQL CE数据库副本。

更改您的连接字符串与SQL CE数据库的确切位置。

例子：

Data Source=C:\\DimaeSQL.sdf;Persist Security Info=False;

看来你使用的是断开连接的数据集。请尝试以下操作：

Organizations table = new DimaeSQLDS.Organizations(); 
using(OrganizationsTableAdapter orgAdapter = new DimaeApplication.DimaeSQLDSTableAdapters.OrganizationsTableAdapter()) 
{ 
    orgAdapter.Fill(table); 
    DimaeSQLDS.OrganizationsRow organizationsRow = table.NewOrganizationsRow(); 
    organizationsRow.Address = tbINN.Text;    
    organizationsRow.OrgName = tbOrgName.Text;   
    dsAddToDima.Organizations.Rows.Add(organizationsRow); //adds row to DataSet 
    orgAdapter.Update(dsAddToDima.Organizations); 
} 

填充（表）是重要组成部分。即使表格为空，它也会启动对数据库的更改跟踪。
