How to Google Analytic Download File Tracking?

· by · in

I create a field called Downloads and attached the code to the download completed event and incremented the download number every time the file was downloaded, I have attached a video of the behavior.

You can utilize the following code in the global.asax to hook to the event:

using System;
using System.Linq;
using Telerik.Sitefinity.Abstractions;
using Telerik.Sitefinity.Libraries.Model;
using Telerik.Sitefinity.Model;
using Telerik.Sitefinity.Modules.Libraries;
using Telerik.Sitefinity.Modules.Libraries.Web.Events;
using Telerik.Sitefinity.Services;
namespace SitefinityWebApp
{
    public class Global : System.Web.HttpApplication
    {
        protected void Application_Start(object sender, EventArgs e)
        {
            Bootstrapper.Initialized += Bootstrapper_Initialized;
        }
        void Bootstrapper_Initialized(object sender, Telerik.Sitefinity.Data.ExecutedEventArgs e)
        {
            if (e.CommandName == "Bootstrapped")
            {
                EventHub.Subscribe<IMediaContentDownloadedEvent>(evt => LibrariesEventHandler(evt));
            }
        }
        public void LibrariesEventHandler(IMediaContentDownloadedEvent eventInfo)
        {
            var userId = eventInfo.UserId;
            var itemUrl = eventInfo.Url;
            var itemType = eventInfo.Type;
            var itemTitle = eventInfo.Title;
            var librariesProviderName = eventInfo.ProviderName;
            var itemMIMEType = eventInfo.MimeType;
            var libraryId = eventInfo.LibraryId;
            var downloadRequestHeaders = eventInfo.Headers;
            var itemId = eventInfo.FileId;
            var manager = LibrariesManager.GetManager();
            var item = manager.GetDocument(itemId);
            var masterItem = manager.Lifecycle.GetMaster(item) as Document;
            var downloads = (decimal)masterItem.GetValue("Downloads");
            var newdownloads = downloads + 1;
            masterItem.SetValue("Downloads", newdownloads);
            manager.SaveChanges();
        }
            
        protected void Session_Start(object sender, EventArgs e)
        {
        }
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
        }
        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {
        }
        protected void Application_Error(object sender, EventArgs e)
        {
        }
        protected void Session_End(object sender, EventArgs e)
        {
        }
        protected void Application_End(object sender, EventArgs e)
        {
        }
    }
}
