    I am using the following call to load a radwindow and it is failing with the above message ...
    Call Telerik.Web.UI.RadScriptManager.RegisterClientScriptBlock(Me.Page, Me.Page.GetType, "LoginWindowScript", "window.radopen('Login.aspx', 'wLoginRegister');", True) 

    The rad window manager code is as:
                    <telerik:RadWindowManager ID="rwmHeader" runat="server" InitialBehaviors="Maximize" EnableEmbeddedSkins="false">  
                            <telerik:RadWindow ID="wLoginRegister" Height="400px" Width="400px" Animation="Fade" runat="server" Modal="true"></telerik:RadWindow> 

    .... and the Ajax ...
    <telerik:RadAjaxManagerProxy ID="rampHeader" runat="server">  
            <telerik:AjaxSetting AjaxControlID="rmMenu">  
                    <telerik:AjaxUpdatedControl ControlID="rwmHeader" LoadingPanelID="ralpHeader" /> 
                    <telerik:AjaxUpdatedControl ControlID="rmMenu" /> 

    Kind Regards

    Hello David,

    I believe that this issue is related to your other forum post for the grid. If the grid is in ajax mode please set EnableAJax to false to resolve this.
