What happens at runtime

Data stored in a DataWindow object is stored within the actual object
itself, so when a window opens showing such a DataWindow, the
data is already there. There is no need to issue Retrieve to
get the data.

PowerBuilder never retrieves data into
a drop-down DataWindow that already contains data. For all other DataWindow objects,
if you retrieve data into a DataWindow object stored with data, PowerBuilder handles
it the same as a DataWindow object that is not stored with data: PowerBuilder gets
the latest data by retrieving rows from the database.
