For a detailed list with the server-side properties and methods of the control, see the Server-Side API of the RadPanelBar class.
RadPanelBar introduces three server-side events for working with panel items:
ItemClick occurs when the user clicks on a panel item.
ItemCreated occurs when a new panel item is added to the panel bar (at any level).
ItemDataBound occurs when a panel item is bound to a data source.
