The modal window is preventing users from clicking outside of the window but it is not preventing users from using tab and focusing on controls from the parent page.  Is there a way to prevent this?

Hello Samuel Davis,

We are aware of this behavior. When you click on the page that is loaded in the RadWindow you set the focus on the IFRAME that holds the content page. That is why you are able to tab away from the IFRAME. Please note that this behavior is not directly related to the RadWindow control, but to the way browsers treat content in IFRAMEs.

In such cases we suggest to create your own JavaScript function that will disable the shortcuts on the page that is loaded in the IFRAME.
e.g..

<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript">
    function DisableShortcuts()
    {
        if (event.keyCode==9)
        {
            return false;
        }
    }
    </script>
</head>
<body onkeydown="return DisableShortcuts();">
    <form id="form1" runat="server">
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
    </form>
</body>
</html>
