Run code every time an ASP.NET page is loaded?

I have to change an existing Web App to enable User Activity logging. For the most part, logging every time someone accesses a page is fine. We've tried extracting the info from the IIS logs but it records the proxy details instead of the user that's logged on.

So then I thought about running code on the Page_Load of every form. The only problem is that this app consists of about 120 forms. I tried putting the code in a base class by performing a search/replace to change the inheritance, but then I get hundreds of warnings about member hiding.

Is there another way of accomplishing what I want to do?

Add a httpModule to your application. Modules are hit for every request so add your logic here.

You can add hook up to one of the events, to get around this issue.

However, the order of the events are not guaranteed - e.g. BasePage.Load may fire before or after InheritedPage.Load.

To be more granular, use the PreInit, Init etc..

Step 1

Do a find/replace for the System.Web.UI.Page to BasePage

Step 2

Add this class to your web project

public abstract class BasePage : System.Web.UI.Page
{
   // Assuming nlog
   private static readonly Logger Logger = LogManager.GetCurrentClassLogger();

   protected BasePage()
   {
      this.Load += new EventHandler(LogPageLoad);
   }

   protected void LogPageLoad(object sender, EventArgs e)
   {
      Logger.Trace("Loading Page: {0}",  this.Title);
   }
}
