Event log

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 panelbar (at any level)
  • ItemDataBound occurs when a panel item is bound to a data source

This example shows how the ItemClick event can be wired up. In your VB or C# code you only need to set the ItemClick event of the RadPanelBar class to the event handler that will process the event. Alternatively, you can use declarative event wiring in your ASPX/ASCX templates.
Please review the source code of this example for additional details.
