The DataBindings collection lets you provide different sets of data bindings to the items on different levels of the panelbar. You can even bind the panel items on each level of the panelbar from different tables in a DataSet.
This example demonstrates how to use databindings to apply declarative mapping of data fields to panel item properties. 

        <telerik:RadPanelBar 
            id="RadPanelBar1" 
            runat="server" 
            DataSourceID="AccessDataSource1"
            DataFieldID="id"
            DataFieldParentID="ParentId">

        <DataBindings>
             <telerik:RadPanelItemBinding TextField="Text" />
             <telerik:RadPanelItemBinding FormatString="Level 1 > {0}" TextField="Text" Depth="1" />
        </DataBindings>

        </telerik:RadPanelBar>
