Both collection properties are of type TreeNodeCollection, which provides standard collection members that enable you to add, remove, and rearrange the nodes at a single level of the node hierarchy. Each TreeNode also has its own Nodes collection to store its child nodes. TREEVIEW WINFORMS WINDOWSThe Windows Forms TreeView control stores the top-level nodes in its Nodes collection. ![]()
