Hi Roland Klug,

Well, you can create it declarative in the markup of the tree, and then add nodes on the client.
Here is a brief example that I prepared for your case:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:ScriptManager runat="server">

</asp:ScriptManager>

<script type="text/javascript">

function onLoad(sender) {

var tree=sender;

var node=new Telerik.Web.UI.RadTreeNode();

node.set_text("Node");

tree.get_nodes().add(node);

}

</script>

<telerik:RadTreeView runat="server" ID="RadTreeView1" OnClientLoad="onLoad">

<ContextMenus>

<telerik:RadTreeViewContextMenu ID="menu">

<Items>

<telerik:RadMenuItem Text="Item1" />

<telerik:RadMenuItem Text="Item2" />

<telerik:RadMenuItem Text="Item3" />

<telerik:RadMenuItem Text="Item4" />

</Items>

</telerik:RadTreeViewContextMenu>

</ContextMenus>

</telerik:RadTreeView>

</div>

</form>

</body>

</html>

Hope this is going to help you!
