webtab and webscriptmanager error
posted

I added a webtab to my web form (version 12.1) and then dragged a webscriptmanager to the form. Everything compiles but when I go to run the form I get this error:

 

Microsoft JScript runtime error: 'Sys' is undefined

Sys.WebForms.PageRequestManager._initialize('ctl00$ContentPlaceHolder1$ScriptManager1', document.getElementById('aspnetForm'));

No matter where I place this code:

    <ig:WebScriptManager ID="WebScriptManager1" runat="server">
    </ig:WebScriptManager>

I get the error. Could you give me direction on how to fix the error?
