I just installed the Tererik Controls to visual studio and when I added the RagOrgChart to my page it added just fine but when I opened it up in my browser it gave me a security warning:  Her is the HTML Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="LeapTree.aspx.vb" Inherits="Pages_Leaps_LeapTree" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
    <form id="form1" runat="server">
    <telerik:RadOrgChart ID="RadOrgChart1" runat="server">

Hello Glen,

Thank you for contacting us.

The exception that you describe does not seem to be caused by the Telerik controls (for a simple test I would suggest that you use any other control and check how the application will behave). Please take a look at the following article that I believe would be very helpful in resolving the issue that you get - System.Web.AspNetHostingPermission Error

I hope this helps. Let me know if you have any other questions that I can assist you with.
