Populating Tree Views
Populating tree views is slightly different because the information is nested in levels inside the tree. There are essentially three ways of filling a tree:
- All levels in one go as a drill-down list. A drill-down list only includes items that contain other items. For example if you had a tree view showing employees by department, a department with no employees would not be shown. See Filling a Drill-Down Tree-View.
- All levels in one go. See Filling a Complete Tree View.
- Every level on demand. See Filling a Tree View on Demand.
