DataBindings 需要Reload()的情况

有一gridview,及对应显示其值的一堆TextEdit

BO.xLookup activeRecord = null;

            private void gridView__FocusedRowChanged(object sender, EventArgs e)
            {
                var z = dlg_Country.gridView_.GetFocusedRowCellValue("PK");
                if (z==null||z.ToString()=="")
                {
                    return;
                }
                activeRecord = _ss.Query<BO.xLookup>().FirstOrDefault(x => x.PK == (long)z);
                foreach (var item in dlg_Country._BOFieldCollection)
                {
                    item.controlBaseEdit.DataBindings.Clear();
                    item.controlBaseEdit.DataBindings.Add(new Binding("EditValue", activeRecord, item.fieldName));
                }
            }

gridview换行事件绑定item值

            private void controlSimpleButton_ClickCancel(object sender, EventArgs e)
            {
                setUIBButton(UIBState.Canceling);
                DisableEdit();
                var z = dlg_Country.gridView_.GetFocusedRowCellValue("PK");
                activeRecord = _ss.Query<TimeShare.BO.xLookup>().FirstOrDefault(x => x.PK == (long)z);
                if (runNew == true)
                {
                    runNew = false;
                    activeRecord = null;
                }
                else
                {
                    activeRecord.Reload();
                }
                foreach (var item in dlg_Country._BOFieldCollection)
                {
                    item.controlBaseEdit.DataBindings.Clear();
                    item.controlBaseEdit.DataBindings.Add(new Binding("EditValue", activeRecord, item.fieldName));
                }
            }

cancel时如果不是新建行那么activeRecord要Reload()

因为修改了TextEdit值时，即使不Save,内存中的值都已改变，就会显示值同Gridview对应不到。

也不是item同activeRecord 的绑定使item.editvalue值改变时，activeRecord对应值也发言为，只是

DB里的值没改变，需要使用Save() 才会保存到DB
