VirtualTreeview

代码说明：

  VirtualTreeviewVirtual Treeview is a treeview control built from ground up. More than 3 years of development made it one of the most flexible and advanced tree controls available today. Virtual Treeview starts off with the claim to improve many aspects of exisiting solutions and introduces some new technologies and priniciples which were not available before. As the name already indicates, this control uses a different paradigm for tree management than other controls of this kind. It does not know anything about the data it manages (except its size), not even the captions of a node. Everything is retrieved from the application via events (or descentants via overridden methods). Virtual Treeview has been carefully designed and thoroughly tested. The control proved its concept as well as everyday fitness already in many commercial products and freeware projects.(VirtualTreeviewVirtual Treeview is a tre eView control built from the ground up.
