The
ExTree component provides the entire range of capabilities you would expect to
see in a state-of-the-art Tree component. The exTree control simulates a
simple tree, a multi-column tree, a list or a listview control. Features
include: skinnable interface, ActiveX hosting (you can place any ActiveX component in any
item of the tree), events from contained components are fired through to your
program using the exact same model used in VB6 for components added at run
time, ADO and DAO support, multiple columns, sorting, multiple selection, user
resizable columns, columns dragable, locked or unlocked columns, cells can be
formatted individually, or via columns or rows, radio buttons, images, check
boxes, multi-line list items, incremental search feature, mouse wheel support,
column alignment right, left, or center, format columns, and more. The ExTree
