Hi Helen

Once again i am afraid the answer is..... I am using an IBOTable component (because I am slowly converting an application from BDE /xBase to IBO / FB.

I assumed that setting the IndexName property of an IBOTable would actually be converted into an SQL Order by clause at some point.

I have changed my refresh to RefreshKeys and every seems to work fine, IBOTable doesn't appear to have a FetchAllRows property. I will just leave it like this :)

Sets in Fb/IB get their ordering from the ORDER BY clause, one way or
another, not from indexes.

I've been watching this thread and wondering why you have such a horror of
a refresh? If your KeyLinks are good, you will get what you want by
defining the appropriate ORDER BY clause, setting FetchAllRows false and
calling RefreshKeys. It's so minimal that, unless the server is on a slow
link, like dialup or ADSL, all the user will see on Post/Autocommit +
RefreshKeys is the new row jumping to its proper position in the grid when
they do whatever it is they do to post a row.

You will probably also want to set RefreshAction to determine where the
cursor lands after the Refresh.
