public partial class Constructor : System.Web.UI.Page {
    protected void Page_Load(object sender, EventArgs e) {
    }
    protected void Create_Nodes() {   
        //Create and list nodes
        TreeViewNode[] ChildList = {
           new TreeViewNode("Inbox", "Mail1", "~/Images/Inbox.png", "Inbox.aspx", "_self"),
           new TreeViewNode("Outbox", "Mail2", "~/Images/Outbox.png", "Outbox.aspx"),

        };
        //Create a parent node and initialize its Text property
        TreeViewNode node = new TreeViewNode();
        node.Text = "MyMail";
        //Add the created list to the node's child collection
        node.Nodes.AddRange(ChildList);
        //Add the node to the ASPxTreeView's child collection
