How to receive notifications of changes in SharePoint groups.

Question

I am really looking for a way to be notified of any changes to a SharePoint group. At first I, although I could do this by associating an event handler with some list of groups. But, unfortunately, there is no such list representing SharePoint groups.

My second attempt was to associate an event handler with a SharePointGroup content type, but that didn't work either.

So are there any other options to receive event notifications in a SharePoint group?

EDIT:

Thanks for the answer.

I forgot to mention that I already played on Google and read the list of users. Unfortunately.

First, I found a forum entry where I posted the relative URL in the list of user data (_catalogs / users / simple.aspx). When I use this link to view the list, it contains only users and groups. I don't know, but maybe this link does some filtering on the list.

Other information that I found on several blogs and forums was that an event handler attached to a list of user data does not start in events. I have to admit after reading that it does not work so many times and even on MSDN ( http://msdn.microsoft.com/en-us/library/aa979520.aspx ), I have not tried this on my own.

The problem associated with the event handler with the content type was not tied, the handler simply did not work when, for example, I changed the name of the group or removed the user from the group. I have no idea why the handler is not called. I am sure that I applied the correct methods and bound them to the correct events.

Any other suggestions on how to get information about changes in SharePoint groups?

It’s actually very annoying that adding or removing from a group does not have an event handler that works best with Google! - enable audit.

Then a periodic loop passes the test to fire my event.

wssQuery = new SPAuditQuery(site); wssQuery.AddEventRestriction(SPAuditEventType.SecGroupMemberAdd); wssQuery.AddEventRestriction(SPAuditEventType.SecGroupMemberDel); wssQuery.SetRangeStart(startTime.AddMinutes(-16)); auditCol = site.Audit.GetEntries(wssQuery); foreach (SPAuditEntry entry in auditCol) { xml.LoadXml("<event>" + entry.EventData + "</event>"); int userId = Int32.Parse(xml.SelectSingleNode("/event/user").InnerText); int groupId = Int32.Parse(xml.SelectSingleNode("/event/groupid").InnerText); if (entry.Event == SPAuditEventType.SecGroupMemberAdd) { // Do Stuff } if (entry.Event == SPAuditEventType.SecGroupMemberDel) { // Do Stuff } } 

This causes a serious delay between adding a member to a group and triggering an event!

I could not find the event handler in the audit, so the only option seems to go through the loop.

This is expensive for me because we have hundreds of site collections!

What do you mean, there is no such list for SharePoint groups? You have a list of user information that hosts both users and SharePoint groups. You can attach event receivers and filter items. For example, you can filter the identifier for the content type of SharePoint groups, which is 0x010b.

In addition, it should be possible to connect event receivers to SharePoint groups. What didn’t work?

.b

Unfortunately, "The list of events does not appear in the list type UserInformation." see http://msdn.microsoft.com/en-us/library/aa979520.aspx or discussion here: http://social.msdn.microsoft.com/Forums/en-US/ea2e06fb-63e1-4096-843c -413ddf33f24b / how-to-add-event-receivers-for-spgroup-in-sharepoint

However, in the case of SP 2013, there is a solution: http://www.c-sharpcorner.com/UploadFile/anavijai/create-groupuseradded-event-receiver-in-sharepoint-2013/
