hi,

I want to change the parent page from which the RadWindow gets called. I can not simply update the whole page. Its a heavy page, and the counter that I am using small asp.net controls. Can you please tell that:

1). Can not I have the reference of the calling page in the server side events of RadWindow. Parent property of RadWindow is set to null, is there any other property by which I can access the calling page of the control reference?

2). Or by some other way I can call the server side method for the parent control on any event in the RadWindow or on the disposal of RadWindow.

Regards

Hello Athir,

RadWindow is based on an IFRAME and by default it displays a content page set with the NavigateUrl property. Note that in this case, these are two completely different documents and you cannot access the server-side logic in one of the pages from the other one.
In such scenario, you should use the client-side API of the control. A sample implementation of such logic is available in this demo. In it, after RadWindow is closed, we use RadAjaxManager's API to invoke an Ajax call that would fire server-side code.

Best wishes,
