My current environment is Microsoft.Net 4.5.2, Visual Studio 2013, AJAX Control Toolkit v15.1. Ever since I upgraded to AJAX Control Toolit v15.1 and use the asp:Scriptmanager instead of the old ToolkitScriptmanager, the tab panels in my tab container for an existing web app become invisible. I think an exception thrown by Javascript when the page is being rendered caused the problem but I don't know how to fix this.
Any suggestion on where to look is deeply appreciated.
Here's an example of a simple page:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="Edesk.WebForm1" %>
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolkit" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<ajaxToolkit:TabContainer ID="TabContainer1" runat="server">
<ajaxToolkit:TabPanel runat="server" HeaderText="Details" ID="TabPanel1" TabIndex="0">
<ContentTemplate>
<table><tr><td>Test details</td></tr></table>
</ContentTemplate>
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="TabPanel2" runat="server" HeaderText="Scope">
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="TabPanel3" runat="server" HeaderText="Approval">
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
<table><tr><td>Test table under tab control</td></tr></table>
</div>
</form>
</body>
</html>
When I run debug I get this error:
Unhandled exception at line 3803, column 12 in http://localhost:56421/ScriptResource.axd?d=LA2uNqtVhxzSGcXjgWiXWMzwtqbnPMUmRP9jH3h0X6l82MORXTdoPhq1uVWN6VYHPOyBjTaf96dObBwHQpWSfAWO9cGXljZJKqL2EtTfofM9x-QAHX3fvuZzmFwummfX2NiNhZ1WtVY-5aKut_Ye8i1-cxlSl5eUqSchmx80oaZ9HLdNmraaCLX7x8ky1_N80&t=7b689585

Uninstall and reinstall doesn't help. I can create a new application and add a new tab container and the tab panels display with no problem. However in the existing application the tab panels wont' show and when I run it in debug mode I see this output from the JavaScript Language Service along with the error described above.
