RadTreeView displays a default context menu which appears when you right-click on a node. This menu contains 7 items and they are:
New: A new sibling node is created.
Edit: An editor appears at the position of the node from which the context menu is invoked. This editor allows you to change a property of the node.
Delete: The node from which the menu is invoked is deleted.
Expand/Collapse: Depending on the expanded state of the node, this menu item may display itself as "Expand" or "Collapse". When click the corresponding operations occurs.
Cut: The node from which the context menu is invoked together with its child nodes (in short - the whole branch) is cut.
Copy: The node from which the context menu is invoked together with its child nodes (in short - the whole branch) is copied.
Paste: If there a cut or copied node (branch), this node is added as a sibling node to the node from which the context menu is invoked.
The default context menu is not enabled by default and if you right-click a node, it will not appear on the screen. In order to enable it, you should set the AllowDefaultContextMenu property to true:
this.radTreeView1.AllowDefaultContextMenu = true;
Me.RadTreeView1.AllowDefaultContextMenu = True
This will display only a small subset of all available menu items. Please note that only the Expand/Collapse item is enabled. All the other items are disabled and below you will see how to enable them.
