    Hi Stev,

    Try to call the function  "BindTreeToDirectory(rootFolder, rootNode);"  (code from the online demo you provided"  in the Upload button click as show below to refresh the treeview after uploading the files.

     protected void UpLoadButtonClick(object sender, EventArgs e)
            { 
            //Write the code to upload the file here

             string rootFolder = Server.MapPath(".");        
             RadTreeNode rootNode = new RadTreeNode(Path.GetFileName(rootFolder));
             rootNode.ImageUrl = "Images/folder.gif";
             rootNode.Expanded = true;
             RadTreeView1.Nodes.Add(rootNode);
             BindTreeToDirectory(rootFolder, rootNode);            
             }
    -shinu.
