As shown in their own example (I’ve reblogged here incase the page ever moves or dissapears!!)

Turns out it’s just a case of setting the “source” property of the XmlTreeNode.

public override void Render(ref XmlTree tree)
{

            Dictionary.DictionaryItem[] tmp;
        //this.id is set when the tree.aspx creates this object.
        //It is the nodeID that is passed in via the tree service parameters (i.e. the query string)
        //this checks if the id is the StartNodeID (root node), if it’s not then this will
        //look up the child nodes for the current dictionary item.
            if (this.id == this.StartNodeID)
                tmp = Dictionary.getTopMostItems;
            else
                tmp = new Dictionary.DictionaryItem(this.id).Children;

            foreach (Dictionary.DictionaryItem di in tmp)
            {
             XmlTreeNode xNode = XmlTreeNode.Create(this);
             xNode.NodeID = di.id.ToString();
             xNode.Text = di.key;
             xNode.Action = string.Format("javascript:openDictionaryItem({0});", di.id);
             xNode.Icon = "settingDataType.gif";
             xNode.OpenIcon = "settingDataType.gif";
             //if there is no children, then set the source to an empty string
//this will ensure that there is no expand button for this node when it is
//rendered. Otherwise, set the source to the tree service url by using
//the BaseTree’s GetTreeServiceUrl method
             xNode.Source = di.hasChildren ? this.GetTreeServiceUrl(di.id) : "";
             tree.Add(xNode);
            }
}

I found an excellent example XSLT that allows you to create a paginated list of child nodes over on Tim Geyssens “nibble” blog, and I’ve modified it ever so slightly to stop the numerical index rendering if the pagecount is less than 2- so thought I would re-post it!
