SP 2010, Is it possible to set permissions at Content Type Level

Question

Say I have a document Library "TravelRequests" and five different content types associated with library. Is there a way to apply permission for a given content type "ManagerCT"? When managers are uploading item to this library they pick ManagerCT content type and load items with metadata. Now I dont want Joe Smith who is custodian to see the items that that has ManagerCT associated with them.

Possible? if yes, how... Any help would be great.

Thanks

Looks like this guy has to solution. I still have to use ItemAdded event handler.

public class ItemSet : SPItemEventReceiver { public override void ItemAdded(SPItemEventProperties properties) { base.ItemAdded(properties);

 SPWeb web = properties.OpenWeb();
 SPList list = web.Lists[properties.ListId];
 SPRoleAssignmentCollection roles = list.RoleAssignments;;

 SPListItem addedItem = properties.ListItem;
 addedItem.BreakRoleInheritance(false);
 foreach (SPRoleAssignment r in roles)
 {
   if (r.Member.Name.ToString().StartsWith(properties.ListItem.ContentType.Name
     .ToString(), StringComparison.CurrentCultureIgnoreCase))
   {
     addedItem.RoleAssignments.Add(r);
   }
 }
 this.DisableEventFiring();
 addedItem.Update();
 this.EnableEventFiring();

} }

You can set a List Item Event Handler on the "TravelRequests" library, override the "ItemAdding" method, which will give you a reference to the actual item (passed in through SPItemEventProperties.ListItem property,) and check for the value of "ManagerCT" being assigned to the item's ContentType field.

If assigned, you can alter the item level permission; (but not without reading the following article describing the gotcha's of doing this programatically):
