    I have a javascript function on a Webform which I call from code behind like below. It works fine without the RadAjaxManager.
     <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

    As soon as I add the script manager and fire the javascript, I get an error in the DOM saying:
    JavaScript critical error at line 343, column 42 in http://localhost:32135/3DPrototypeQuote.aspx\n\nSCRIPT1004: Expected ';' 

    Note there is a semicolon missing between NovaCopyStlViewer('/assets/Inverted.stl') and Sys.Application.add_init(function()) , here is where the Visual Studio is telling me there is a semi colon missing. 

    <script type="text/javascript">
    NovaCopyStlViewer('/assets/Inverted.stl')Sys.Application.add_init(function() {
        $create(Telerik.Web.UI.RadAjaxManager, {"_updatePanels":"","ajaxSettings":[],"clientEvents":{OnRequestStart:"",OnResponseEnd:""},"defaultLoadingPanelID":"","enableAJAX":true,"enableHistory":false,"links":[],"styles":[],"uniqueID":"ctl00$ContentPlaceHolder1$RadAjaxManager1","updatePanelsRenderMode":0}, null, null, $get("ctl00_ContentPlaceHolder1_RadAjaxManager1"));

                    FileUpload fileUpload = FileUploadControl;

                    string physicalFolder = Server.MapPath("~/assets/");
                    if (fileUpload.HasFile)
                        string uploadFile = physicalFolder + fileUpload.FileName;

                        string testFile = "/assets/" + fileUpload.FileName;
                       ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "NovaCopyStlViewer('" + testFile + "')", true);
                catch (Exception)


     <script type="text/javascript">
            function NovaCopyStlViewer(file)

                var cv = document.getElementById('canvas_drop');
                cv.style.display = 'block';

                var e = document.getElementById('select_options');
                e.style.display = 'block';

                var mycanvas = document.getElementById('upload_canvas');
                var viewer = new JSC3D.Viewer(mycanvas);
                var theScene = new JSC3D.Scene;

                var stlpath = file;
                viewer.setParameter('SceneUrl', stlpath);
                viewer.setParameter('InitRotationX', 20);
                viewer.setParameter('InitRotationY', 20);
                viewer.setParameter('InitRotationZ', 0);

    Hi Felix,

    Please review the attached project it shows how this could be implemented. In your project you should add semicolon at the end of the function's definition.
    ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "NovaCopyStlViewer('" + testFile + "');", true);
