Open Radwindow with different domain

[Niranjan]

I have a main page opening a radwindow with URL pointing to another domain. Now is there a way to track the rad window closing in the opening domain?

Main Page: https://www.sitename.com/subdomain1/mainpage.aspx

Radwindow URL: https://www.sitename.com/subdomain2/windowpage.aspx

When the Radwindow is closed i am able to trigger an event in "subdomain1/mainpage.aspx". But i would like to trigger an event (server side or client side) in "subdomain2/windowpage.aspx".

Hello Niranjan,

You can try the OnClientBeforeClose event and access the child page where you can call some JavaScript function depending on your scenario.

• https://docs.telerik.com/devtools/aspnet-ajax/controls/window/client-side-programming/events/onclientbeforeclose

Otherwise, you can use the main page server-side to execute the needed logic as the RadWindow loads the child page in an iframe, which is inaccessible on the server-side.

Peter,

Thanks for the response. But the OnClientbeforeclose event is firing only in the calling page, in this case https://www.sitename.com/subdomain1/mainpage.aspx. But i want to handle something before the window closes in the Radwindow page (different domain) https://www.sitename.com/subdomain2/windowpage.aspx.

Hello Niranjan,

Yes, the function is called on the main page because that is where the RadWindow resides. 

My suggestion was to use this event in the main page, access the child page via JavaScript and execute some predefined function inside the child page.

Since the child page is in a different sub domain i am not sure if security will allow java script to be invoked from parent page. Do you have a sample code for this?

Hello Niranjan,

When the NavigateURL is passed to the RadWindow, it just loads the url in an <iframe> element. That means the same approach would work and the same issues will occur as if you were loading your child page in a simple <iframe>. 

Also, you can find the following article helpful to accessing the child page if the loaded page allows it:
