End-users can add new nodes by clicking the New command button. This switches the ASPxTreeList to edit mode, and allows new node values to be edited. To add a new node to the underlying data source, click the Update button.

The StartEditNewNode method raises the ASPxTreeList.InitNewNode event, which enables you to initialize added nodes in code. To save a new node, call the ASPxTreeList.UpdateEdit method.
