Set text to combobox in 1. window from 2. window

[wnl]

Hi,
in my case I have two radwindows.
In the first I have RadComboBox, and in the second I have a button with javacript functions.
In this function I want to set text to RadComboBox in 1. window.
I want to have only js code in the second window.
I'm trying to use code from sample DialogReturnValue:

                //get a reference to the second RadWindow
                var dialog1 = oWnd.get_windowManager().getWindowByName("RadWindow1");

                // Get a reference to the first RadWindow's content
                var contentWin = dialog1.get_contentFrame().contentWindow

                //Call the predefined function in Dialog1
                //contentWin.populateCityName(selectedCapital);
                contentWin.$find("<%= RadComboBox11.ClientID %>"); //error

but there is an error that RadComboBox11 doesn't exist.
I want to ask, is it possible to do something like this?

Hello Jaromin,

This error is expected - $find() will work only in the context of the page from which it was called - in your scenario, the RadComboBox is in the other window and that is why you are getting this error.
I suggest to put that last line of code in a function in your other page (e.g. where the RadComboBox is) and then to call it by using contentWin.MyFunctionName(some_argument) - just like shown in the commented line in your code.
