Kevin,

I am using a treeview to change the controls I display on the page. I do it like this:

 /// <summary>
        /// Left Menu Node Click Handler
        /// </summary>
        /// <param name="sender">Sender</param>
        /// <param name="e">EventArgs</param>
        protected void tvAboutMenu_NodeClick(object sender, RadTreeNodeEventArgs e)
        {
            if (e.Node.Value.Length < 3)
                return;

            if (e.Node.Value.Substring(0, 3) == "BIO")
            {
                this.bioName = e.Node.Value.Substring(3, e.Node.Value.Length -3).ToUpper();
                this.DisplayContent(AboutDisplayType.Biography);
            }
            else
            {
                switch (e.Node.Value)
                {
                    case "History":
                        this.DisplayContent(AboutDisplayType.History);
                        break;
                    //case "ByLaws":
                    //    Response.Redirect("~/Resources/MSAbylaws.pdf", false);
                    //    break;
                    case "Chart":
                        this.DisplayContent(AboutDisplayType.OrgChart);
                        break;
                    case "Corner":
                        this.DisplayContent(AboutDisplayType.ChairmansCorner);
                        break;
                    case "Board" :
                        e.Node.Expanded = true;
                        this.bioName = "KELLEY";
                        this.DisplayContent(AboutDisplayType.Biography);
                        break;
                    case "Chapters" :
                        e.Node.Expanded = true;
                        break;
                }
            }
           
        }

You have to set the node values for each node to something you can use in this event to determine which node was selected.
The DisplayContent method creates the UserControl and adds it to the page.
