For developers: Pages events

The following articles describes the events exposed by pages in Sitefinity.

IUnauthorizedPageAccessEvent

This interface is implemented by all events which fire when a page in the site is accessed by an unauthorized user. There's only one such built-in event, but you should always subscribe using the interface rather than the class that implements it. Use the following code to subscribe.

EventHub.Subscribe<IUnauthorizedPageAccessEvent>(evt => IUnauthorizedPageAccessEventHandler(evt));

  In the event handler, you can access the following information:
  • The HTTP Context for the page which was accessed.
  • The PageSiteNode object for the page itself.
  • The redirect strategy used.
  • The URL to which the user was redirected.
public void IUnauthorizedPageAccessEventHandler(IUnauthorizedPageAccessEvent eventInfo)
{
    var currentContext = eventInfo.HttpContext;
    var page = eventInfo.Page;
    var redirectStrategyType = eventInfo.RedirectStrategy;
    var redirectUrl = eventInfo.RedirectUrl;
}

IPagePreRenderCompleteEvent

 An interface of the event notifying that a page's PreRender event has completed.
The event is raised at 'PreRenderComplete' event of ASP.NET page lifecycle. A subscription for this event can be created by using the EventHub. Use the following code to subscribe:

EventHub.Subscribe<IPagePreRenderCompleteEvent>(this.OnPagePreRenderCompleteEventHandler);

In the event handler, you can access the following information:
  • The PageSiteNode object for the page itself
  • The Page itself
Once the event is being handled, the user can use it to modify a sitefinity dynamic page. In the example below all back-end pages are hidden from navigation:

private void OnPagePreRenderCompleteEventHandler(IPagePreRenderCompleteEvent evt)
        {
            if (evt.PageSiteNode.IsBackend)
            {
                evt.PageSiteNode.ShowInNavigation = false;
            }
        }
