Should be ok. Be sure to run it through SPDisposeChecker (http://code.msdn.microsoft.com/SPDisposeCheck). Event receivers have the potential to run a lot and should be checked every time, because if they leak you will find out very quickly :-)

This is working quite well with only a few limitations. The main one being that items being updated (either via update copy or overwrite) are not being affected. Excuse my naivety but could I simply re-use the code below, replacing ItemAdded with ItemUpdated, and push out a new event type to attach to the library? using System; using System.Collections.Generic; using System.Text; using Microsoft.SharePoint; namespace CEO.Intranet.DocumentCentre.Library { public class ItemEventHandler: SPItemEventReceiver { public override void ItemAdded(SPItemEventProperties properties) { base.ItemAdded(properties); SPListItem originalItem = properties.ListItem; string url = properties.WebUrl; SPListItem item = null; SPSecurity.RunWithElevatedPrivileges(delegate() { try { using (SPSite site = new SPSite(url)) { using (SPWeb web = site.OpenWeb()) { item = web.Lists[properties.ListId].GetItemById(properties.ListItemId); } } } catch (Exception) { try { using (SPSite site = new SPSite(url)) { using (SPWeb web = site.OpenWeb()) { SPList list = web.Lists[originalItem.ParentList.ID]; item = list.Items[originalItem.UniqueId]; } } } catch (Exception ex1) { Console.WriteLine(ex1.Message); } } if (item != null) SetSecurityForNewItem(item); }); } private void SetSecurityForNewItem(SPListItem newItem) { //SPListItem newItem = newFile.Item; try { newItem.BreakRoleInheritance(true); SPGroupCollection groupCollection = newItem.ParentList.ParentWeb.Groups; SPRoleDefinitionCollection roleDefinitions = newItem.ParentList.ParentWeb.RoleDefinitions; char[] seperator = new char[] { ';' }; string groupPermissions = newItem["Group Permissions"].ToString(); string[] permissionGroups = groupPermissions.Split(seperator); bool removeReadPermissions = true; if (permissionGroups[1] != "#All Portal Users") { foreach (SPGroup spGroup in groupCollection) { removeReadPermissions = true; foreach (string subString in permissionGroups) { if (subString.Length > 1 && spGroup.Name == subString.Substring(1)) { removeReadPermissions = false; } } if (removeReadPermissions) { SPRoleAssignmentCollection roleAssignmentCollection = newItem.RoleAssignments; foreach (SPRoleAssignment roleAssignment in roleAssignmentCollection) { if(roleAssignment.Member.Name == spGroup.Name) { SPRoleDefinitionBindingCollection roleDefBindings = roleAssignment.RoleDefinitionBindings; if (roleDefBindings.Contains(roleDefinitions["Read"])) { roleDefBindings.Remove(roleDefinitions["Read"]); roleAssignment.Update(); } } } } } } } catch (Exception ex) { Console.WriteLine(ex.Message); } } } } Regards, Paul Online Developer, ICT CEO Sydney ________________________________ Support procedure: https://www.codify.com/lists/support List address: [email protected] Subscribe: [email protected] Unsubscribe: [email protected] List FAQ: http://www.codify.com/lists/ozmoss Other lists you might want to join: http://www.codify.com/lists -------------------------------------------------------------------------------- Support procedure: http://www.codify.com/lists/support List address: [email protected] Subscribe: [email protected] Unsubscribe: [email protected] List FAQ: http://www.codify.com/lists/ozmoss Other lists you might want to join: http://www.codify.com/lists
