Use the EditNode to programmatically edit the giving node. The EditNode method focuses the control's window, ensures that the giving node fits the control's edit node, and edit the node's caption. The EditNode method starts editing the giving node, if the control is enabled and visible, and the node is editable ( Editable property ). The LayoutStartChanging(exEditNode) event notifies your application once a node is being edited. The LayoutEndChanging( exEditNode) event notifies your application once a node is edited. The Caption property indicates the caption of the node being edited.
