Find control inside window from parent window

[Dmitry]

Hello,
I have a page, which opens a dialog window (Window1). In Window1 there's a custom AJAX control with button which in turn opens new dialog window (Window2). When Window2 closes, a page must handle Window2's OnClientClose event, and Window2 must pass some data to my custom control on WIndow1. To avoid stack overflow, as you adviced here, I put handler on main page.
And now I want to get data sent by Window2 and put them to my control on Window1. This is how I'm doing that now:

 function referenceWindowClose(sender, args) {
            sender.remove_close(referenceWindowClose);
            var arg = args.get_argument();
            if (!arg) return;
            var ctl = $find(arg.TargetControlID);
            if (ctl == null) return;
            ctl.set_text(arg.Caption);
            ctl.set_value(arg.RefID);
        }

Variable named ctl is my custom AJAX control. Problem is ctl is always null. I know this happens because Window1 is in IFRAME. But how do I find it from main page? Using sender parameter? Please help.

Hi Dmitry,

You would first need to access the iframe of Window1. This can be done by getting a reference to this first RadWindow and calling a function that is declared in its content page, which populates the desired value. You can pass the custom argument as a parameter in these functions. I.e. the following bit should be in the page, loaded within RadWindow1:

function populateValue(arg)
{
    var ctl = $find(arg.TargetControlID);
    if (ctl == null) return;
    ctl.set_text(arg.Caption);
    ctl.set_value(arg.RefID);
}

and on the main page you should call it in a similar way:

if (!arg)
{
     return;
}
else
{
    var oWnd = GetRadWindowManager().getWindowByName("RadWindow1");
    oWnd.get_contentFrame().contentWindow.populateValue(arg);
}

How to call a function from another RadWindow is explained here.
