Thank you very much, Tom . Works beautifully.

Hi

I've been thinking that it would be a very useful feature if one could "embed" or add the functionality of common visual components as nodes in a teetree. For example, is there a way of adding a drop-down listbox as a node to a teetree? Something like a drop-down lookup list in a DBGrid.

I had a similar problem, but I've recompiled the source and my code now works like a charm. Thank you Peter for posting this kind advice.
