代码附上： 

void UCHouseholdRegisterInfoList_Load(object sender, EventArgs e)
        {
            BusinessService.CommunityBasicInfo.HouseholdRegisterInfoService service = new BusinessService.CommunityBasicInfo.HouseholdRegisterInfoService();
            IList<Tc_ge_rpr> householdInfoList= service.GetHouseholdRegisterInfoList();
            this.dgvHouseholdRegisterInfo.DataSource = householdInfoList;
            UIHelper.AddIndexToView(dgvHouseholdRegisterInfo);
        }

UIHelper方法如下

        /// <summary>
        /// 向datagridview添加自动编号
        /// </summary>
        /// <param name="view"></param>
        public static void AddIndexToView(DataGridView view)
        {
            try
            {
                view.Columns.Add(new DataGridViewTextBoxColumn() {Name = "dataGridviewIndex", HeaderText= "编号" });
                view.Columns["dataGridviewIndex"].DisplayIndex = 0;
                for (int i = 0; i < view.Rows.Count; i++)
                {
                    view.Rows[i].Cells["dataGridviewIndex"].Value = i + 1;
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

我在普通的form里试验过没有任何问题，但是在WeifenLuo继承过来的窗体里就不会显示，但是如果在按钮事件里添加又可以，不知道是什么原因，我觉得不是加载事件顺序不对，因为普通的Form可以实现，哪位高手遇到过这种问题，给予帮助
