Hi,

I created a Telerik MVC Web Application from the Template
added a tabstrip to the master page
syntax is fine, it seems, but it throws a null reference exception

site.master:

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

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

<head runat="server">

<title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title>

<link href="../../Content/Site.css" rel="stylesheet" type="text/css" />

<%= Html.Telerik().StyleSheetRegistrar().DefaultGroup(group => group.Add("telerik.common.css").Add("telerik.hay.css").Combined(true).Compress(true))%></

head>

<body>

<div class="page">

<div id="header">

</div>

<div id="main">

<div id="content">

<%

Html.Telerik().TabStrip()

.Name("SiteTabStrip")

.Items(items =>

{

items.Add()

.Text("Create New")

.Action("xxxx", "New");

items.Add()

.Text("xxxxx")

.Action("xxxxx", "xxxxx");

items.Add()

.Text("xxxxx")

.Action("xxxx", "xxxx");

items.Add()

.Text("xxxxx")

.Action("xxxx", "xxxxx");

items.Add()

.Text("Documents")

.Action("xxxx", "Documents");

})

.Render();

%>

<asp:ContentPlaceHolder ID="MainContent" runat="server" />

</div>

<div id="footer">

</div>

<%= Html.Telerik().ScriptRegistrar().DefaultGroup(group => group.Combined(true).Compress(true)) %></body>

</html>
