Erm, good question, a place where I have floundered before.

Now, here's what I think I've done, to get at an event to cause
CalculateField to be called. There is a dataset property
CalculateAllFields which, if set true, will cause CalculateField to be
called on each of the calculated fields in the current row as soon as *any*
field in the row gets modified in the buffer. As long as your calculated
field setup is all nicely in place, I think that will do the trick.

Sorry I can't provide any practical examples, but I can't find anything
where I've actually used client-side calc fields. Being a very
server-focused individual, I confess I use the query spec to calculate
them. It seems like one to put on the to-do list for a tech info sheet,
doesn't it?

cheers,
Helen
