When trying to call a JavaScript function from the Codebehind, an error occurs stating that the identifier 'ScriptManager' is not recognized within the current context

How can I call a JS function via codebehind without postback on a site? I've placed my script before the closing <head> Tag:

<script type="text/javascript">
    function StartWidgetTour() {
        //initialize the tour
        wWidgetTour.init();

        //start the tour
        wWidgetTour.restart();
    }
</script>

This is how my code looks like:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "Widget Tour Start!", "StartWidgetTour()", true);
        //more working code here

However, when I try to run this code, I get the error message:

The name 'ScriptManager' does not exist in the current context
.

I have already included the namespaces System.Web and System.Web.UI;. The solutions provided in this question did not work for me.

Any assistance would be greatly appreciated!

To incorporate a scriptmanager into the *.aspx page, follow these steps:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true">
</asp:ScriptManager>
