Has there been a resolution to this error. I'm getting a similar error with a later version:
System.Runtime.Serialization.SerializationException: Type 'Telerik.Web.UI.RadTreeNode' in Assembly 'Telerik.Web.UI, Version=2013.3.1015.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' is not marked as serializable. at

Below I have provided sample code. To replicate with the below code the sessionState Mode will have to be set to SqlServer or StateServer.

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

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

<!DOCTYPE html>

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

<head runat="server">

<title></title>

</head>

<body>

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

<div>

<telerik:RadScriptManager runat="server" ID="radscrptmnger"></telerik:RadScriptManager>

<telerik:RadTreeView ID="treeAction" runat="server" CheckBoxes="false" Visible="true"

Font-Size="11px" BackColor="#FFFFFF" Skin="Sunset" OnNodeClick="TaskTree_NodeClick">

<expandanimation duration="100" />

<nodes><telerik:RadTreeNode Value="test" Text="test"></telerik:RadTreeNode></nodes>

</telerik:RadTreeView>

</div>

</form>
