Hi Jin,
The '
RefreshMode' enum has two values - 'PreserveChanges' and 'OverwriteChangesFromStore'.
The 'OverwriteChangesFromStore' will re-read all data while refereshing; all dirty fields will be re-read and all changes will be lost and the object will be marked as clean. If I understand you right, this is what you want to achieve.
Do get back in case you need further assistance.
