6.15.4 Tree View
Use a tree view to show hierarchical data.
A tree view is a good way of presenting, for example:
- Files grouped by directories
- Employees grouped by departments
- Orders grouped by customers and customers grouped by area
You can nest several levels of information, but in most cases it is clearest not to use more than two or three levels.
The images in the tree view are defined using the Image and ImageExpanded properties of the individual tree view columns.
