Microsoft JScript runtime error: 'undefined' is null or not an object

[hkdave95]

Hi

I get this error when I choose Customer->Login from the menu on my website at http://daresoft.no-ip.co.uk/the-dl-outlet.

IT fails on the "return" line ... it seems that GetRadWindowManager cannot find the RadWindowManager.

window.radopen=function(url,_1b){
var _1c=GetRadWindowManager();
return _1c.open(url,_1b);
};

The call to load the window is :

                Call Telerik.Web.UI.RadScriptManager.RegisterClientScriptBlock(Me.Page, Me.Page.GetType, "LoginWindowScript", "window.setTimeout(function(){ radopen('pages/Login.aspx', 'wLoginRegister'); }, 0);" & vbCrLf, True)

The WindowManager is ...

                            <telerik:RadWindowManager ID="rwmHeader" runat="server" InitialBehaviors="Maximize" Animation="Fade" Behaviors="Maximize, Close" Skin="Default" Modal="true">
                                <Windows>
                                    <telerik:RadWindow ID="wLoginRegister" Height="300px" Width="610px" runat="server" VisibleStatusbar="false" VisibleTitlebar="true" Title="Login" OnClientClose="window.location.reload();">
                                    </telerik:RadWindow>
                                </Windows>
                            </telerik:RadWindowManager>

Any ideas ?

Kind Regards

David

Hi David,

Try increasing the timeout in your call and see how your logic will behave. In addition, I suggest to use the ASP.NET AJAX way for finding the controls - $find().


If you still experience this problem, please try isolating it in a separate project and send it to us for investigation.


All the best,
