# 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.

```C#
using System;
using Telerik.Sitefinity.Abstractions;
using Telerik.Sitefinity.Services;
using Telerik.Sitefinity.Web.Events;

namespace SitefinityWebApp
{
   public class Global : System.Web.HttpApplication
   {

       protected void Application_Start(object sender, EventArgs e)
       {
           Bootstrapper.Bootstrapped += Bootstrapper_Bootstrapped;
       }

       private void Bootstrapper_Bootstrapped(object sender, EventArgs e)
       {
           EventHub.Subscribe<IUnauthorizedPageAccessEvent>(evt => UnauthorizedPageAccessEventHandler(evt));
       }

       public void UnauthorizedPageAccessEventHandler(IUnauthorizedPageAccessEvent eventInfo)
       {
           var currentContext = eventInfo.HttpContext;
           var page = eventInfo.Page;
           var redirectStrategyType = eventInfo.RedirectStrategy;
           var redirectUrl = eventInfo.RedirectUrl;
       }
   }
}
```

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.

## 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](https://msdn.microsoft.com/en-us/library/ms178472.ASPX). A subscription for this event can be created by using the EventHub. Use the following code to subscribe:

```C#
using System;
using Telerik.Sitefinity.Abstractions;
using Telerik.Sitefinity.Services;
using Telerik.Sitefinity.Web.Events;

namespace SitefinityWebApp
{
   public class Global : System.Web.HttpApplication
   {

       protected void Application_Start(object sender, EventArgs e)
       {
           Bootstrapper.Bootstrapped += Bootstrapper_Bootstrapped;
       }

       private void Bootstrapper_Bootstrapped(object sender, EventArgs e)
       {
           EventHub.Subscribe<IPagePreRenderCompleteEvent>(this.OnPagePreRenderCompleteEventHandler);
       }

       private void OnPagePreRenderCompleteEventHandler(IPagePreRenderCompleteEvent evt)
       {
           var page = evt.Page;
           var pageNode = evt.PageSiteNode;
       }

   }
}
```

In the event handler, you can access the following information:

* The PageSiteNode object for the page itself
* The Page itself

## Personalized pages events

**IPersonalizedWidgetRenderEvent**

If the visitors browsing the page are associated with certain audience segments and in case the page has personalized versions of widgets created for these specific segments, the `IPersonalizedWidgetRenderEvent` is fired. The event is fired for each personalized widget.

Since there is just one such built-in event, you always subscribe using the interface rather than the class that implements it. Use the following code to subscribe:

```C#
using System;
using Telerik.Sitefinity.Abstractions;
using Telerik.Sitefinity.Personalization.Impl.Web.Events;
using Telerik.Sitefinity.Services;

namespace SitefinityWebApp
{
   public class Global : System.Web.HttpApplication
   {
       protected void Application_Start(object sender, EventArgs e)
       {
           Bootstrapper.Bootstrapped += Bootstrapper_Bootstrapped;
       }

       private void Bootstrapper_Bootstrapped(object sender, EventArgs e)
       {
           EventHub.Subscribe<IPersonalizedWidgetRenderEvent>(evt => PersonalizedWidgetRenderEventHandler(evt));
       }

       private void PersonalizedWidgetRenderEventHandler(IPersonalizedWidgetRenderEvent evt)
       {
           var segmentName = evt.SegmentName;
           var widgetId = evt.WidgetId;
           var pageUrl = evt.PageUrl;
           var onPageTemp = evt.IsOnPageTemplate;
       }
   }
}
```

In the event handler, you can access the following information:

* Segment name
* Widget ID
* Page URL
* Origin from where the event is fired
