If you want to execute the javascript, you better write

RegisterStartupScript("key","<script>refreshCont()</script>");

and keep the function refreshCont() in your js file.

is "window.parent.frame.content is null or not an object." the error message in verbatim? if so, then the error is not in the script you gave, it might be somewhere else where "window.parent.frame.content" is referenced. Is the first snippet a server-side JScript, by the way?

To be more clear,

HTML
====
<head>
<script src='../../Scripts/Helper.js'></script>
<script>
function refreshCont () {
     window.parent.frames['content'].location = '../Welcome.aspx';
}
</script>
</head>

CODE-BEHIND
=========
RegisterStartupScript("key","<script>refreshCont()</script>");

try giving the frame number.

like if you have top frame, left frame and middle frame, and you are trying to change the middleframe from left frame, then give window.parent.frames[2].location = '../Welcome.aspx';

frames['content'] is the name of frame

frames['content'] should suffice if the parent page has a frame named "content." Kind of a blind guess here, but maybe it's not the topmost frame; you can try window.top.frames['content'].location. :)

If you get the "same" error, i.e., "window.parent.frame.content is null or not an object", perhaps it's saying that we're fixing the wrong thing.

Maybe this can help you debug:

if (!window.parent) { alert("There is no parent.");
if (!window.parent.frames) { alert("There is no frames in this window's parent.");
var frms = '';
for (var i in window.parent.frames) { frms += i + '/'; }
alert("The frames of the parent window are: " + frms);

Also, may we see your <framset><frame...></frameset> code?

So let me get this -- the frame page contains top.aspx/menu.aspx/welcome.aspx/bottom.aspx -- and then one of these pages calls a popup window, that contains the code in your question?

...If that's the case, try window.opener.top.frames['content'].location.
