Since the two pages are entirely separate there are several ways you can achieve passing the value from one to the other:
1) build the data on the content page, store it in the session, cache or database and when closing the RadWindow perform an AJAX request in the main page to get it. Similar approach is shown in this online demo
and this online demo
. You can take it from the server to the client in your content page easily, for example in a hidden field or by directly injecting the script
3) change the URL of the main page to provide the argument as a querystring, e.g.: window.top.location.href = window.top.location.href + "?CustomerID=" + myData Note that this will fully reload the parent page.
