[v2.x only] Using postbacks with panelbar items

RELATED TO:

HOW-TO
Enable postbacks with panelbar items(v2.x only) 

SOLUTION
RadPanelBar allows postbacks through the familiar AutoPostBack property (false by default). At postback the panelbar raises the ItemClicked event. The event handler of the event is supplied with a PanelbarItem object, alowing to determine the value of Label, Id and all other supportted <Item> attributes.

NOTE
 Only <Item>s that specify a value to the Href attribute will perform a postback. This is done with the reasoning that expanding headers should not cause a postback to the server. Please review the example in the panelbar installation example framework to better understand the ItemClicked event.
