    In main page which contains the radwindowmanager, I added an radwindow "G" under the radwindowmanager. After I opened the radwindow "G", I tried to open another radwindow "C" from radwindow "G" by using the code below.

    function openWindow(Url, Id) {

                var oMan = GetWindowManager();

                var oWnd = oMan.open(Url, Id);

                oWnd.set_visibleStatusbar(false);

                oWnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Resize);

                //something wrong here

                oWnd.setActive();

                return oWnd;

    }

    however I got the error message below 
    'telerik.web.ui.windowBehahaviors.close' is null or not an object.

     in web.config, I added 

    <location path="Telerik.Web.UI.WebResource.axd">

        <system.web>

          <authorization>

            <allow users="*" />

          </authorization>

        </system.web>

      </location>

     
    please advise what cause this issue? Thanks.

    Hi,

    You should get a reference to the parent page(where the RadWindowManager is) and use parentPage.Telerik.Web.UI.WindowBehaviors.Close instead of
    Telerik.Web.UI.WindowBehaviors.Close .
    I created for you a simple example, which illustrates how to open a RadWindow from a button which is inside another RadWindow.
