    I have a very convoluted problem to try and describe to you all.

    I have a RadWindow that is being opened from a User Control using show().

    This works just fine. When the window's Save button is clicked a Client side java script function
    is called to close the window and pass a parameter.

    An OnClientClose function is then called which gets an Ajax Manager and triggers an ajaxRequest
    which is handled by the user control.

    I have a second situation where I am hosting the same User Control inside another RadWindow.

    To get the second level RadWindow to display correctly I have to get the appropriate Window Manager
    and call the open function on that window manager, passing the aspx and window name.

    This seems to create a separate instance of the RadWindow which I have to programatically configure
    with my required attributes, however I cann't wire up the close using add_close because of the stack overflow problem.
    I tried the work around you mention in one of your articles. However that doesn't help either.

    What I REALLY need is some way of notifying the first level RadWindow that the second level window has closed and it has a parameter being passed to it.  

    Re-reading this I wonder if any of this will make sense, but I cann't figure out a solution so I thought I'd try and explain the problem.

    Hi Tim,

    I am not sure I understand you completely, yet I can suggest you try a combination of the following
    - a check if you are inside a RadWindow (which is explained here and here)
    - in case you are in a RadWindow you can avoid using a OnCilentClose handler, but instead simply call a function from the parent page in the same place where you close the second level RadWIndow (i.e. the button OnClientClick handler)

    This may require that you add a function to handle this logic in all parents that may host your user control, however, yet there isn't a better approach to handle a user control that depends on its context, as generally user controls should not depend on the context/parent. You could further extend this if you like to use the same approach for all cases - i.e. calling a function from the parent page instead of an onclientclose handler.

    Kind regards,
