Dream InfoTree
TDCTree control - 100% VCL treeview control which is not based on standard TTreeView and that is why you don't have to worry whether your users have the latest version of COMCTL32.DLL. DCTree is completely compatible with TTreeView and supports all standard properties/events. However it goes far beyond repeating TTreeView. It handles nodes with different fonts and even different font sizes. Great features (like multiselect, checkboxes etc.) are combined with incredible speed - it takes just no time to load 100000 items to DCTree and it still works very fast and absolutely flicker free.
