EntityDataSource

    • Agua de Horchata
      • Agua de Horchata con Canela
    • Agua de Jamaica

This example shows how to codelessly bind RadPanelBar to EntityDataSource. Since the EntityDataSource is not hierarchical by nature you need to set the DataFieldID and DataFieldParentID properties: 

<telerik:RadPanelBar runat="server" ID="RadPanelBar1" 
    DataSourceID="EntityDataSource1" DataTextField="Text" 
    DataFieldID="id" DataFieldParentID="parentId" >
</telerik:RadPanelBar>
<asp:EntityDataSource runat="server" ID="EntityDataSource1" 
	ConnectionString="name=TelerikReadWriteEntities"
	DefaultContainerName="TelerikReadWriteEntities" EntitySetName="Links">
</asp:EntityDataSource>
