with an approach of this type, it should be easier to put the treeview and the button on a panel, set the panel border to bsNone, its color to clWindow and voilà... Probably, simply setting the Button.Owner (owner, not parent) to the treeview should help in the Button's Onclick event handler to easily interact with it. I am not writing code ATM so maybe something I said regarding properties (owner, parent etc. etc.) is faulty, but you got the sense, right? Just my 2c. Cheers, A.
