SharePoint 2010 Document Library Replicator: Part 3

Today I added the following changes to the solution:

1 – Added a ReplicatorLogger Class to the solution.

2 – Updated the Feature Receiver code to create a Replicator logger list in the Web.

3 – Updated the ItemUpdated method in the Event Receiver to write to the Replicator Logger list when an item is added or updated.

The following code is the new ReplicatorLogger Class:

internal class ReplicatorLogger


publicvoid writeToLog(string title, string logDate, string modifiedBy, string action, string copySource, string fileName, SPWeb web)


 // Get the current httpcontext

 System.Web.HttpContext currentContext = System.Web.HttpContext.Current;

 // Set the httpcontext to null;

 HttpContext.Current = null;

 using (web)




 // Create an item the Replicator Logger list to record the event

 SPList spList = web.Lists[“Replicator Logger”];

 SPListItem logItem = spList.Items.Add();

logItem[“Title”] = title;

logItem[“Log Date”] = logDate;

logItem[“Modified By”] = modifiedBy;

logItem[“Action”] = action;

logItem[“Copy Source”] = copySource;

logItem[“File Name”] = fileName;



 catch (SPException spEx)





 // Set the httpcontext back to the original

 System.Web.HttpContext.Current = currentContext;





The following code was added to the Feature Receiver to create the Replicator logger list:

 // Create the replicator logging list

 spWeb.Lists.Add(“Replicator Logger”, “Document Library Replicator Logging List”, spWeb.ListTemplates[“Custom List”]);

 SPList replicatorLoggingList = spWeb.Lists[“Replicator Logger”];

replicatorLoggingList.NoCrawl = true;

replicatorLoggingList.Fields.Add(“Log Date”, SPFieldType.Text, true);

replicatorLoggingList.Fields.Add(“Modified By”, SPFieldType.Text, true);

replicatorLoggingList.Fields.Add(“Action”, SPFieldType.Text, true);

replicatorLoggingList.Fields.Add(“Copy Source”, SPFieldType.Text, true);

replicatorLoggingList.Fields.Add(“File Name”, SPFieldType.Text, true);


 // Update the default view to show the new fields

SPView spLogView = replicatorLoggingList.DefaultView;

spLogView.ViewFields.Add(“Log Date”);

spLogView.ViewFields.Add(“Modified By”);


spLogView.ViewFields.Add(“Copy Source”);

spLogView.ViewFields.Add(“File Name”);


The code below updates the Event Receiver to also write the properties to the Replicator Logger list:

public overridevoid ItemUpdated(SPItemEventProperties properties)



 using (SPSite spsite = newSPSite(properties.WebUrl))



EventFiringEnabled = false;

 if (properties.ListItem.ParentList.Title != “Replicator Logger”)


 SPWeb siteForLogger = spsite.OpenWeb();

 // determine target filename – the same as the source

 string targetfilename = properties.ListItem.Name.ToString();

 string SourceLib = properties.WebUrl + “/” + properties.ListItem.ParentList.ToString();

  // Copy the file to the destination library (targetlibrary)

 properties.ListItem.File.CopyTo(properties.WebUrl + “/” + “targetlibrary” + “/” + targetfilename, true


 // Write to the Replicator Log – in test mode…

 ReplicatorLogger replogger = newReplicatorLogger();

 // Get the current Date and Time

 DateTime dtime = DateTime.Now;

 // Create the title for the logger list item

 string title = (dtime.Date.ToString() + “_” + dtime.Hour.ToString() + “_” + dtime.Minute.ToString() + “_” + dtime.Second.ToString() + “_” + targetfilename.ToString());

 // Write the information to the logger list

 EventFiringEnabled = false;

replogger.writeToLog(title, dtime.ToShortDateString(), properties.UserDisplayName.ToString(),“New/Updated Document”, SourceLib, targetfilename, siteForLogger);



catch (SPException spEx) { }



  // Enable Event Firing

 EventFiringEnabled = true;



Here is an example of the item created in the Replicator Logger list when an item is uploaded or updated:
