problem with TreeListNode

I'm trying to create a treelistnode. The following below code getting an error:

        private TreeListNode CreateTreeNode(EntityInfo entity)
        {
             CategoryInfo info = entity as CategoryInfo;

             TreeListNode treeNode = new TreeListNode();
             treeNode.SetValue("CatName", info.CatName);
             treeNode.SetValue("CateCode", info.CateCode);
             treeNode.SetValue("Id", info.Id);
             treeNode.Tag = info.Id;

             return treeNode;
         }

Error

I need your help to create a separate treelistnode Thanks!

You should use the TreeList's AppendNode method instead. Please also refer to the How to: Create Nodes in Unbound Mode in Code topic.
