Flexible TreeView allows you to change the appearance and behavior of every part of the treeview. To control the treeview appearance and behavior use the Options treeview property.
Here is the description of those options that didn`t appear in other articles.
Treeview`s scroll bars are accessible in the HorzScrollBar and VertScrollBar properties. You can hide them by disabling the Options.Appearance.ShowHorzScroll and Options.Appearance.ShowVertScroll properties respectively.
When a treeview contains long nodes, it may be hard to view all content of this treeview. Flexible TreeView allows you to greatly improve working with this kind of data by introducing a smart vertical scroll - when you scroll the treeview vertically, it tries to locate the best horizontal position to view currently visible nodes, and then scrolls to that position automatically. You can disable this behavior by disabling the Options.Behavior.SmartVerticalScroll property.
