When you change the key field in master dataset, detail dataset is automatically refreshed. If you want to refresh the detail dataset after any master field is changed, use the AfterPost event for the master and call the Refresh method for the detail dataset in this event.

It is not true if you are inserting a master record

If you are inserting a master record, previously inserted detail records are not refreshed wher you fill the masterfield. It is incredible this is happening, since there are many situations this may be necessary.
