How to: Add and Remove Nodes with the Windows Forms TreeView Control Using the Designer
Because the Windows Forms TreeView control displays nodes in a hierarchical manner, when adding a node you must pay attention to what its parent node is.
The following procedure requires a Windows Application project with a form containing a TreeView control. For information about setting up such a project, see How to: Create a New Windows Forms Application Project and How to: Add Controls to Windows Forms.
Note
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Working with Settings.

To delete nodes, select the node to delete and then click the Delete button.
