Remarks

Tip

Topic: Add and Remove Rows

Use the AddNewNode method to add a new node to the view’s underlying datasource. The View immediately reflects any changes made to the datasource and focuses the new node.

When a new node is added, the datasource may initialize some values (key fields, for instance). Records can also be initialized by handling the TreeListView.AddingNewNode event.

Refer to the Add and Remove Rows topic for more information.
