The code below demonstrates how you can handle the ASPxTreeView.VirtualModeCreateChildren event to create the TreeViewVirtualNode objects.

using System.Collections.Generic;
using DevExpress.Web.ASPxTreeView;

public partial class _Default : System.Web.UI.Page {

    protected void Page_Load(object sender, EventArgs e) {
    protected void treeView_VirtualModeCreateChildren(object source, TreeViewVirtualModeCreateChildrenEventArgs e) {
        //Create and list nodes
        TreeViewVirtualNode[] nodeList = {
            new TreeViewVirtualNode("Mail1", "Inbox", "Images/Inbox.png", "Inbox.aspx", "_self"),
            new TreeViewVirtualNode("Mail2", "Outbox", "~/Images/Outbox.png", "Outbox.aspx"),
            new TreeViewVirtualNode("Mail3", "Deleted Items", "~/Images/Deleted.png"),
            new TreeViewVirtualNode("Mail4", "Draft"),
            new TreeViewVirtualNode("Mail5")

        //Add text to the last created node
        nodeList[4].Text = "Junk E-mail";

        //Set the nodes' IsLeaf property to true to hide their expand buttons
        foreach (TreeViewVirtualNode node in nodeList) {
            node.IsLeaf = true;
        e.Children = new List<TreeViewVirtualNode>(nodeList); ;
