Streamlining Content Sync in Sitefinity with Event-Driven .NET Integration
Keeping content in sync across multiple websites can quickly become a bottleneck without the right automation in place. Visus developed an event-driven integration in Sitefinity that streamlines synchronization, ensuring updates happen instantly and accurately after each sync. The result is faster, more reliable content delivery and greater control across complex digital ecosystems.

Synchronizing content across multiple Sitefinity sites is a critical task for clients managing distributed digital ecosystems. However, efficiently retrieving all items once Sitefinity's SiteSync process completes can be complex and time-consuming without the right approach.

SiteSyncModule.SyncCompleted += new EventHandler<SyncCompletedArgs>(OnSiteSyncCompleted);

Visus tackled this challenge by implementing an event-driven solution leveraging Sitefinity's native SiteSync events. The core innovation involved subscribing to the OnSiteSyncCompleted event, which triggers immediately after a sync operation finishes. By attaching an event handler in .NET like:

{  
    var summaryId = e.SummaryId;  
    SiteSyncManager siteSyncManager = SiteSyncManager.GetManager();  
    SiteSyncSummary summary = siteSyncManager.GetSiteSyncSummary(summaryId);  
     
    var entries = siteSyncManager.GetLogEntries().Where(x => x.Status == "Synced").ToList(); 
}


The process gains direct access to sync details in real time. Inside the handler, the code retrieves the specific sync summary and filters log entries marked as “Synced,” enabling precise identification of the successfully synchronized items:

This approach runs on the source site—the origin of the data—highlighting the importance of correctly configuring SiteSync's source and target sites to ensure seamless data flow.

From this implementation, the key lesson emerged: tapping into Sitefinity's built-in events streamlines synchronization workflows and offers granular control over post-sync processes. This method eliminates the need for costly and error-prone polling or manual checks, empowering clients to maintain consistent, up-to-date content across environments.

By combining Sitefinity's extensibility with thoughtful .NET integration, Visus delivered a solution that not only enhances operational efficiency but also lays a foundation for scalable content management in complex digital landscapes.
