The DataBindings collection lets you provide different sets of data bindings to the nodes on different levels of the treeview. You can even bind the nodes on each level of the treeview from different tables in a DataSet.

This example demonstrates how to use databindings to apply declarative mapping of data fields to treeview node properties.
<telerik:RadTreeView runat="server" ID="RadTreeView1" DataSourceID="SqlDataSource1"
DataFieldID="id" DataFieldParentID="parentID" Skin="Vista" CheckBoxes="true">
		<telerik:RadTreeNodeBinding TextField="Text" />
