Hi Frank,
Welcome to MSDN Managed Newsgroup. My name is Lingzhi Sun [MSFT]. It's my
pleasure to work with you on this ADO.NET problem.
DataSet.GetChanges(), with no parameters, returns a copy of the DataSet
that contains all changes(added, modified, and deleted) made to it since it
was loaded or since AcceptChanges was last called. If GetChanges() is
called when the new row is added but the user has not modified it, we get a
DataSet which contains all the original data and the new row with default
values. However, if GetChanges() is called after the user has modified the
new row, we get a DataSet that contains all the original data and the new
row with modified values.
Please note: Once the new row is added into the DataSet, its DataRowState
is set to Added. Before the changes are accepted or reset, even if the new
row is modified, its DataRowState is still Added instead of Modified.
Frank, could you please clarify when the GetChanges is called? Before the
new row is modified or after that? Also, did you pass any parameters to
the GetChanges method to filter the data or just call the GetChanges with
no parameters?
If you have any questions or concerns, please feel free to let me know.
Have a nice day!
Best Regards,
Lingzhi Sun
