Control Child page inside the radpane from main page

[WebDeveloper]

I have a webpage that has a label, radsplitter and radpane, lets call it PageHost. In the radpane I load a page by changing the ContentURL property, lets call this page PageChild.

If from PageChild inside the radpane, I want to get handle to the label on PageHost, how do I do that?

Hi,

You can get reference to the PageHost from within the PageChild through window object, e.g.:

var pageHost = window.parent;

Then you can call functions registered on PageHost to get reference to the label control.

More detailed information on the subject is available in the following KB article:

This seems to work on client side. How do I get it to work on the serve side. i.e. what would be the equivalent of window.parent on the server side?

Hi,

In short, no, you cannot access the parent's page object on the server. This is not a restriction of RadSplitter but a general ASP.NET restriction. When using ContentUrl property to load the content of a RadPane the page is loaded in an <iframe> element.

All the best,
