    I am using a radwindow. In single aspx page its working correctly. But now am using a master page and its content page; Rad window palced in content page inside a ContentPlace Holder. But now its throws a following javascript error.

    1)    "Microsoft JScript runtime error: Object expected"

    How to solve this? My codes given below.


    <script type="text/javascript">
      
        function openRadWindow(Url, WindowName) {
            var oWnd = radopen(Url, WindowName);
            oWnd.center();
        }
      
    </script>

    protected void RadToolBar1_ButtonClick(object sender, Telerik.Web.UI.RadToolBarEventArgs e)
        {
      
            switch (e.Item.Value)
            {
                case "FileAttachment": FileAttachment();
                    break;
                case "PredefinedWorkFlow": PredefinedWorkFlow();
                    break;
                case "ManualWorkFlow": ManualWorkFlow();
                    break;
            }
      
        }
     protected void PredefinedWorkFlow()
        {
            RadWindowPredefinedWorkFlow.VisibleOnPageLoad = true;
      
            string nm = RadWindowPredefinedWorkFlow.ClientID;
      
            string Script1 = "<SCRIPT LANGUAGE='JavaScript'> ";
            Script1 += "openRadWindow('PredefinedWorkFlow.aspx','RadWindowPredefinedWorkFlow')";
            Script1 += "</SCRIPT>";
      
            ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "open", Script1, false);
        }

    Hello Pradeep,

    RadControls for ASP.NET AJAX are built on MS AJAX framework and they all, including RadWidnowManager (radopen is a part of the RadWidnowManager), require that framework to be loaded on the page in order to use their client-side objects. This means that, you need to call the radopen method after the MS AJAX's load event. More details about how to achieve this can be found in this KB article (radalert is a part of the RadWindowManager as well).

    I hope this helps.

    Kind regards,
