Nodes correspond to items within the hierarchical data. Nodes are represented by TreeViewNode objects. A node can have its own child nodes collection, available via the TreeViewNode.Nodes property. These child nodes have their own children, etc.

The parent node for all nodes, displayed within the ASPxTreeView, is called the root node. This is a special node which isn't displayed. The collection of its child nodes can be accessed via the ASPxTreeView.Nodes property.

The node content can include a check box, an image and a text. The table below lists the main properties which affect the node content:

A node has a set of properties responsible for a node's state. The tables below list the main properties which specify the node's state:
