Panel Bar - Flat Data

You can provide a collection of flat data to the Data parameter of the TelerikPanelBar. Flat data means that the entire collection of PanelBar items is available at one level. The parent-child relationships are created through internal data in the model - the ParentId field which points to the Id of the item that will contain the current item. The root level has null for ParentId. Such data binding can be useful to create Frequently Asked Questions section.
