Ian,

I don't have any practical experience with SET KEY. Once I found the problem with a filtered grid back in VFP3 I switched to using the LinkMaster, RelationalExpr and ChildOrder grid properties. I did two production apps and just ran into too many other headaches, so I've been using p-views for the last 4 apps.

So SET KEY may get this app out the door quicker for you and it works. I'd recommend using p-views on the next app though.

>I noticed SET KEY in the suggestions below and did some research/testing on it. It appears to function quite well. Do you beleive that SET KEY is a more efficient/faster way of connecting tables than SET FILTER???
