在更新后重新填充网格时，单击时将数据移动到下一个单元格

Question

填充网格视图，然后在单元格上单击i填充单元格单击事件上的文本框，如

   private void dgvCompany_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            int i = dgvCompany.SelectedCells[0].RowIndex;
            ID = dgvCompany.Rows[i].Cells[0].Value.ToString();
            txtCompanyName.Text = dgvCompany.Rows[i].Cells[1].Value.ToString();
            txtContactName.Text = dgvCompany.Rows[i].Cells[2].Value.ToString();
            txtContactPersonPhone.Text = dgvCompany.Rows[i].Cells[3].Value.ToString();
            txtAddress.Text = dgvCompany.Rows[i].Cells[4].Value.ToString();
            txtCity.Text = dgvCompany.Rows[i].Cells[5].Value.ToString();
            txtPhone.Text = dgvCompany.Rows[i].Cells[6].Value.ToString();
            cbIsActive.Checked = Convert.ToBoolean(dgvCompany.Rows[i].Cells[7].Value);
        }

这里ID是填充文本框后的字符串变量我编辑并保存更新，然后像以前的方法一样重新填充网格，

public void FillCompanyInfo()
        {
            DataTable dtCompanyInfo = objFunctions.GetCompanyInfo();
            if(dtCompanyInfo.Rows.Count>0)
            {

                dgvCompany.DataSource = dtCompanyInfo;
                if (this.dgvCompany.Columns.Count == 8)
                {
                    DataGridViewCheckBoxColumn checkColumn = new DataGridViewCheckBoxColumn();
                    checkColumn.Name = "";
                    checkColumn.HeaderText = "Select";
                    checkColumn.Width = 50;
                    checkColumn.ReadOnly = false;
                    checkColumn.FillWeight = 10; //if the datagridview is resized (on form resize) the checkbox won't take up too much; value is relative to the other columns' fill values\\
                    dgvCompany.Columns.Add(checkColumn);
                }
            }
        }

这里我使用if条件计数列为8，因为每次添加列选择并在再次填充网格后，当我单击网格并单击单击事件触发错误时，

在线，

 ID = dgvCompany.Rows[i].Cells[0].Value.ToString();

找不到对象引用，因为它在单元格0上变为null，而在单击单击更新之前它正常工作，当我使用断点时，我在单元格[1]上获取ID并且单元格[0]为空

我不理解这个错误

希望你的建议
