Excellent, thanks for the info Greg. That should get me under way. Phil.

So you need to override the Getowner method of TCollection and TCollectionItem. Have a look at the DBGrid code as it may help. You probably also want to override the GetDisplayName property of the collection item to provide a custom name for each item. Another good book for getting into the VCL is Marco Cantu's Delphi Developers Handbook. See www.marcocantu.com or www.sybex.com I bought it from the US for about $100. If you buy it in NZ it is about $160. >1). How do I pass a sub component to the Object Inspector (ala menu >editor)? > >2).
