C# ImageListBoxControl组件根据主键自动定位选择行记录

                //重新定位记录
                var list = tlCategory.DataSource as List<dt_CommonDataDictType>;
                var obj = list.Where(w => w.DataType == row.DataType).FirstOrDefault();
                if (obj != null)
                {
                    tlCategory.SelectedIndex = list.IndexOf(obj);
                }
