On my main form I have a Treeview and a picturebox which project forms get placed into using SetParent API. When the Treeview looses focus the selecteditem no longer appears selected. I'm not sure if I've simply missed something very simple or I have an interesting problem on my hands. Anyhow I'd like the selectedItem of the treeview to appear selected when it looses focus .. just like in windows explorer when you've selected a file in the listview you can still tell which folder is selected. Any help in the right direction would be appriciated.
