的DataGridView RowValidation错误

Question

我真的用不可思议的方式同步我的数据，从电网到数据库：

例如：

#region Line methods 
private void LinesView_UserDeletedRow(object sender, DataGridViewRowEventArgs e) 
{ 
    lineTableAdapter.Update(fRIIBDataSet.Line); 
} 

private void LinesView_CellValueChanged(object sender, DataGridViewCellEventArgs e) 
{ 
    lineTableAdapter.Update(fRIIBDataSet.Line); 
} 

private void LinesView_RowValidated(object sender, DataGridViewCellEventArgs e) 
{ 
    lineTableAdapter.Update(fRIIBDataSet.Line); 
} 
#endregion 

，但是当我打开一些列组合框我需要做一些技巧之前更新类似于：

private void dataGridView1_RowValidated(object sender, DataGridViewCellEventArgs e) 
{ 
    //deltaTableAdapter.Update(fRIIBDataSet.Delta); TODO 
} 

private void dataGridView1_UserDeletedRow(object sender, DataGridViewRowEventArgs e) 
{ 
    deltaTableAdapter.Update(fRIIBDataSet.Delta); 
} 

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) 
{ 
    if (lambdacat != null) 
    { 
     string selected = (LimView.Rows[e.RowIndex].Cells[1] as DataGridViewComboBoxCell).FormattedValue.ToString(); 
     if (selected != "") 
     { 
      int find = Array.IndexOf(dict, dict.Where(x => x == selected).FirstOrDefault()); 
      LimView.Rows[e.RowIndex].Cells[0].Value = dictiddarray[find]; 
      //deltaTableAdapter.Update(fRIIBDataSet.Delta); 
     } 
    } 
    //deltaTableAdapter.Update(fRIIBDataSet.Delta); 
} 

解除更新方法后会出现问题。

当我用表格打开窗口时出现错误信息：内部索引损坏DataTable：“5.”如何修复/避免此错误？

Answer 1

是否修改它为这项工作？

if (selected != "") 
    { 
     int find = Array.IndexOf(dict, dict.Where(x => x == selected).FirstOrDefault()); 
     LimView.Rows[e.RowIndex].Cells[0].Value = dictiddarray[find]; 
     fRIIBDataSet.Delta.BeginInit(); // 
     deltaTableAdapter.Update(fRIIBDataSet.Delta); 
     fRIIBDataSet.Delta.EndInit(); 
    }
