I have declared the scriptManager in the Main Master page. This Master page calls a control which needs the TabStrip control on it.
When the code for instantiating radstripcontrol is added I get the following error: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
My MasterPage code is:
<body>
<form id="form1" runat="server">
<telerik:RadScriptManager ID="ScriptManager1" runat="server" ScriptMode="Release"
EnablePageMethods="True" EnableScriptCombine="False"
EnableScriptGlobalization="True">
</telerik:RadScriptManager>
<cc:Navigation ID="navSite" runat="server" />
<div>
<asp:ContentPlaceHolder ID="cphTop" runat="server"></asp:ContentPlaceHolder>
</div>
<br />
</form>
</body>
The code on the Control is:
<%@ Import Namespace="System.Xml" %>
<%@ Control Language="C#" AutoEventWireup="true"
CodeFile="~/controls/Navigation.ascx.cs" Inherits="controls_Navigation" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<!-- Navigation -->
<table class="nav" cellspacing="0" cellpadding="0">
<tr class="navrow"><td colspan="2">
<table class="navrow" cellspacing="0" cellpadding="0">
<tr id="navrow1">
<asp:Repeater ID="repNav" runat="server">
<ItemTemplate>
<telerik:RadTabStrip ID="ItemDetailTabStrip" runat="server" SelectedIndex="0" MultiPageID="TabStripMultiPage"
Skin="Outlook" BorderColor="#B3C17D" Width="958px" >
<Tabs>
<telerik:RadTab Text="Key Fields & Smart Terms™" BorderColor="#B3C17D">
</telerik:RadTab>
<telerik:RadTab Text="Results" BorderColor="#B3C17D">
</telerik:RadTab>
</Tabs>
</telerik:RadTabStrip>
</ItemTemplate>
</asp:Repeater>
<td style="width:100%; text-align:right; padding: 0px 0px 5px 0px;"
> </td>
</tr>
</table>
</td></tr>
</table>
Could you please advise me what to do to overcome the persistent error?
Thanks.

Could you specify the version of our controls that you are using and under which browser you had faced the described issue?
