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.
The AddNewNode method is only available for datasources which support the following interfaces:
- IBindingList
- ICollectionView
- INotifyCollectionChanged
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.
