c＃Datagridview bindingsource

Question

這是我的程序的當前剪輯，因爲它是，datagridview斷開連接到數據表，如果我更改dataviewgrid上的任何東西，它不會反映在數據表中...我怎樣才能使它這樣datagridview上的任何編輯都可以反映到至少數據表中？

 OpenFileDialog OFD = new OpenFileDialog(); 
     OFD.Title = "CSV File"; 
     OFD.Filter = "Spreadsheet | *.csv"; 
     OFD.ShowDialog(); 

     FileHelperEngine engine = new FileHelperEngine(typeof(csv_SeatingPlan)); 
     try 
     { 
      csv_SeatingPlan[] container = engine.ReadFile(OFD.FileName) as csv_SeatingPlan[]; 
      CSV_Seating_Plan = new List<csv_SeatingPlan>(container); 

      DataTable DT_student_Records = new DataTable(); 
      DT_student_Records.Columns.Add("Exam_Period", typeof(string)); 
      DT_student_Records.Columns.Add("Exam_Code", typeof(string)); 
      DT_student_Records.Columns.Add("Student_ID", typeof(string)); 
      DT_student_Records.Columns.Add("Student_Name", typeof(string)); 
      DT_student_Records.Columns.Add("Candidate_Number", typeof(string)); 


      foreach (csv_SeatingPlan row in CSV_Seating_Plan) 
      { 
       DT_student_Records.Rows.Add(row.examperiod, row.exam_Code, row.id_Student, row.name_Student, row.candidatenum_Student); 
      } 

      DT_student_Records.DefaultView.Sort = "Candidate_Number ASC"; 
      this.dataGridView1.DefaultCellStyle.Font = new Font("Tahoma", 11); 
      //bindingCSVSP.DataSource = DT_student_Records; 
      this.dataGridView1.DataSource = DT_student_Records;

爲了傳播更改到基礎數據源（你的情況表），你應該使用BindingSource對象。如何做到這一點的一個例子是在鏈接頁面的底部。
