      Hi,All

           Pls see the flowing code, it can only update parent Item references with the same folder child items,or else nothing change at the end.

       

           If delete "fileItem.UnlockFile(0, "API AddChildItems", (int)EdmUnlockFlag.EdmUnlock_Simple, null);" then run, may see the references in the items explorer,but can not see check in dialog, that is the problem.

       

           could somebody help me  solve this problem?

              public static bool AddChilds(int parentItemId, List<IEdmItem> childItems, IEdmVault11 vault)
        {
            bool flag = true;
            if (null == MyEdmItem.GetItemById(parentItemId, vault) || childItems.Count <= 0)
            {
                return false;
            }
            foreach (IEdmItem it in childItems)
            {
                if (null == it)
                {
                    flag = false;
                    return false;
                }
            }

            int num = childItems.Count;
            Array addRefs = Array.CreateInstance(typeof(EdmItemRef), num);
            EdmItemRef[] tmpAddRefs = new EdmItemRef[num];
            IEdmItem parentItem = MyEdmItem.GetItemById(parentItemId, vault);
            for (int i = 0; i < num; i++)
            {
                EdmItemRef iref = new EdmItemRef();
                iref.moParentNamePathOrItemID = parentItemId;
                iref.moNamePathOrID = childItems[i].ID;
                iref.mlEdmRefFlags = (int)EdmRefFlags.EdmRef_Item+(int)EdmRefFlags.EdmRef_Static;
                tmpAddRefs[i] = iref;
            }
            addRefs = tmpAddRefs;
            
            Array removeRefs = null;
            
            
            IEdmFile8 fileItem = (IEdmFile8)parentItem;
            if (!fileItem.IsLocked)
            {
                try
                {
                    fileItem.LockFile(vault.RootFolderID, 0, (int)EdmLockFlag.EdmLock_Simple);
                }
                catch (System.Exception e)
                {
                    vault.MsgBox(0, e.Message, EdmMBoxType.EdmMbt_OKOnly, "");
                    return false;
                }
            }

            parentItem.UpdateReferences(ref addRefs, ref removeRefs);
            
            fileItem = (IEdmFile8)parentItem;
            fileItem.Refresh();
            try
            {
                 fileItem.UnlockFile(0, "API AddChildItems", (int)EdmUnlockFlag.EdmUnlock_Simple, null);
            }
            catch (System.Exception e)
            {
                vault.MsgBox(0, e.Message, EdmMBoxType.EdmMbt_OKOnly, "");
                return false;
            }
           return flag;
        }
