Remarks
Use the AppendNode method to append a new node to the specified node’s child collection. Use the parentNodeId parameter to specify the parent node by its identifier. Node identifiers are returned by the TreeListNode.Id property. To add a node at the root level, the parentNodeId parameter must be set to the value of the TreeList.RootValue property.
The nodeData parameter specifies data for the columns of the node that is to be created. This parameter value can be an array of values or a DataRow object. The number and order of items in the array/DataRow object must match the number and order of Tree List columns.
