代碼使用：

        string[] workType = new string[4] { "-1", "關閉但不刪除", "啟用", "刪除" };        void gvLampConfig_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)        {            GridView _view = sender as GridView;            _view.CustomValidatingEditor(e, fieldName => fieldName.Equals("TLampWorkStatus"), value => !workType.Contains<string>(value.ToString()), "若想設定為不修改，請輸入-1即可");        }
