I have seen this--when I call Read before HasRows or bind the rowset to a
complex bound control.

Details, details, .....
private void timer_Tick(object sender, EventArgs e)
{
if (dsNonMembers.HasChanges())
{
SetButtons(true);
}
else
{
if (bsNonMembers.Count > 0)
{
if
(((DataRowView)bsNonMembers.Current).Row.HasVersion(DataRowVersion.Proposed))
{
SetButtons(true);
}
}
}
}
EndEdit writes the changes to the dataset. With one row, you have to peek.
If a Proposed is found, call EndEdit on the underlying binding source and
the write your changes back to the database.

EndEdit() (called on the table) worked like a charm; I needed to GetChanges()
so checking for proposed changes unfortunately wasn't sufficient. EndEdit
doesn't seem to cause any issues regardless of row state, so I'm content with
just calling it directly within the operation for now.
Much appreciated!
