如何在c编辑datagridview后更新我的数据库＃

Question

我正在尝试使用单击DataGridView2的单元格，然后获取单击单元格的值以编辑DataGridView1的选定单元格。但是，adder.update无法将编辑的数据更新到数据库。

此代码用于获取DataGridView2单击的单元格值，以编辑DataGridView1的选定单元格值。

private void DataView2_CellClick(object sender, DataGridViewCellEventArgs e) 
      { 
       int TempCellIndex; 
       int TempRowIndex; 
       TempCellIndex = DataView1.CurrentCell.ColumnIndex; 
       TempRowIndex = DataView1.CurrentCell.RowIndex; 
       CellChangeContext = DataView1.CurrentCell.Value.ToString(); 
       try 
       { 
        if (((btnFlag != 2) && (btnFlag != 3)) || (TempCellIndex < 2)) 
         return; 
        DataView1.Rows[TempRowIndex].Cells[TempCellIndex++].Value = DataView2.Rows[e.RowIndex].Cells[0].Value; 
        MessageBox.Show(DataView1.Rows[TempRowIndex].Cells[TempCellIndex-1].Value.ToString()); 
        if (DataView1.CurrentCell.Value.ToString().Equals(CellChangeContext)) 
         return; 
        else 
         DataView1.CurrentCell.Style.ForeColor = System.Drawing.Color.Red; 
        if (CellIndex == 22) 
         DataView1.Rows[TempRowIndex].Cells[TempCellIndex - 1].Selected = false; 
        else 
        { 
         DataView1.Rows[TempRowIndex].Cells[TempCellIndex].Selected = true; 
         DataView1.CurrentCell = DataView1.Rows[TempRowIndex].Cells[TempCellIndex]; 
        } 

       } 
       catch (Exception ex) 
       { 
        MessageBox.Show(ex.Message); 
       }; 
      } 

此代码是通过单击按钮实现数据库的更新。

private void btnSAVE_Click(object sender, EventArgs e) 
     { 
      if ((btnFlag == 2)||(btnFlag == 3)) 
      { 
       DataView1.ReadOnly = true; 
       EnableBtn(); 
       this.mST_RECIPETableAdapter.Update(this.processRecipe.MST_RECIPE); 
       this.mST_RECIPETableAdapter.Fill(this.processRecipe.MST_RECIPE); 
       this.DataView1.ClearSelection(); 
      } 
      if (btnFlag == 4) 
      { 
       DataView2.Columns["pRNCDataGridViewTextBoxColumn"].ReadOnly = true; 
       EnableBtn(); 
       this.mST_PROCTableAdapter.Update(this.processOption.MST_PROC); 
       this.mST_PROCTableAdapter.Fill(this.processOption.MST_PROC); 
      } 


     }

我已经自己解决了这个问题。关键是在更新之前添加mSTRECIPEBindingSource.EndEdit();。
