Hello.

Any time I put a ScriptManager in my login page, I get this error message Uncaught SyntaxError: Unexpected token '<' and my login control does not get decorated.

What can it be?

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Login.aspx.vb" Inherits="SmartERP.Login" %>

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

<!DOCTYPE html>

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

<head runat="server">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

<title>Smart-ERP</title>

<script type="text/javascript">

function GetWndSize() {

var w = screen.width;

var h = screen.height;

document.getElementById('TxtOcultoWidth').value = w;

document.getElementById('TxtOcultoHeight').value = h;

}

</script>

</head>

<body onload="GetWndSize()">

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

<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />

<asp:TextBox runat="server" ClientIDMode="Static" ID="TxtOcultoWidth" EnableViewState="true" style="display:none"/>

Thank you very very much!!!! In deed It semms I found the answer with your second step. It was a permission issue (only happens in login page when our website denies access to all pages to unauthorized users). I leave here my solution it someone need it:

Just add this in the configuration file:

<configuration>

...

<location path="Telerik.Web.UI.WebResource.axd">

<system.web>

<authorization>

<allow users="*"/>

</authorization>

</system.web>

</location>

...

</configuration>
