I have guestion regarding sharepoint groups.
I have a list for Client. Now when i add new item to Client list, the group of Client name has to be create in SharePoint. I have created an Event reciever of ItemAdding event.
Is it possible to do that? If yes then how?
Since you already have the event receiver a simple google search of how to create a sharepoint 2010 user group returns several helpful tutorials.
