PanelBar / Persist State in Cookie


  • Normally, the state of RadPanelBar would be lost when navigating between pages unless you programmatically persist it or use the PersistStateInCookie property. This example demonstrates the latter- just set the PersistStateInCookie property to true.

    State restoring occurs before the PreRender event of RadPanelbar. You can access the SelectedItem by subscribing to the PreRender (DataBound if you use declarative datasources) event.

    Please review the code sections for more details.
