Sys.ArgumentNullException: value cannot be null: parameter name: panelsCreated[6]

[Joseph]

Hi,

I am experiencing an exception Sys.ArgumentNullException: value cannot be null: parameter name: panelsCreated[6].

Not sure what is causing it, but I suspect the exception has something to do with RadWindow since it occurs when I open a RadWindow repeatedly.

Thanks in advance.

The markup for the 2 RadWindows are as follows:

<telerik:RadWindowManager ID="Singleton" runat="server" Animation="None" Behaviors="Move"
        Width="900px">
        <windows>
            <telerik:RadWindow ID="rwProtoResponseMediaEdit" Behaviors="Move, Resize, Maximize" Skin="Telerik"
                VisibleStatusbar="false" ReloadOnShow="false" OnClientClose="rwProtoResponseMediaEdit_ClientClose"

                Modal="true" NavigateUrl="~/Agency/Search/ResourceSearch.aspx"
                Width="800" Height="650">
            </telerik:RadWindow>
            <telerik:RadWindow ID="rwPatientProfileEdit" Behaviors="Move, Resize, Maximize" Skin="Telerik"

                NavigateUrl="~/Agency/Authoring/PrototypeSummary.aspx">

        </windows>
    </telerik:RadWindowManager>

 

The javascript for opening the RadWindows are as follows:

function OpenProtoResponseMediaEdit(prid, prrrsi)
            {
                var url = '<%= ConvertRelativeUrlToAbsoluteUrl("~/Agency/Authoring/ProtoResponseMediaEdit.aspx") %>';
                url = url + "?prid=" + prid + "&prrrsi=" + prrrsi;

                logsafe(url);

                var oWnd = $find("<%= rwProtoResponseMediaEdit.ClientID %>");
                //oWnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Resize + Telerik.Web.UI.WindowBehaviors.Maximize);
                oWnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Resize + Telerik.Web.UI.WindowBehaviors.Maximize);
                oWnd.show();
                oWnd.setSize(950, 800);
                oWnd.setUrl(url);
                oWnd.minimize();
                oWnd.maximize();
                oWnd.restore();
                oWnd.center();
            }

            function rwProtoResponseMediaEdit_ClientClose(sender, args) {

                var arg1 = args.get_argument();

                //logsafe("rwProtoResponseMediaEdit_ClientClose");
                //logsafe(arg1);
                if (arg1 && arg1.indexOf('ok') === 0) {
                    SetNeedToConfirm('true');
                    //alert('needToConfirm = true');
                }

                var hidAddOptionsMediaAjax = $('#' + '<%=hidAddOptionsMediaAjax.ClientID%>');
                var btnAddOptionsMediaAjax = $('#' + '<%=btnAddOptionsMediaAjax.ClientID%>');

                hidAddOptionsMediaAjax.val(arg1);
                btnAddOptionsMediaAjax.click();
            }

 //Get current RadWindow
                    function GetRadWindow() {
                        var oWindow = null;

                        var oManager = oWindow.get_windowManager();

                        setTimeout(function () {

                            var winResourceSearch = oManager.getWindowByName("rwResource");
                            //winResourceSearch.remove_close(rwResource_ClientClose); // Remove the close handler, if exist
                            winResourceSearch.add_close(rwResource_ClientClose); // Set the close handler

                            oManager.open(null, "rwResource"); // Open RadWindow via RadWindowManager
                        }, 0);
                    }

                    }

Hi Joseph,

We are not aware of the reported behavior and, unfortunately, the provided code was not enough to reproduce it at our end. Can you provide a little more details on the exact scenario in which the problem occurs?

• Can you verify that there are no any JavaScript errors thrown on the page?
• Can you verify that you are using the latest version of the controls like stated into the ticket info?
• In case you are using AJAX updates, can you try to disable the AJAX on the page and see whether the problem persists?

Last but not least, can you, please, try to isolate the issue into a stand-alone project following the instructions of this blog post and send it so we can examine it further?

Regards,
Vessy
