If you want to execute the javascript, you better write

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

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

aescnt

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?

viveksg

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>");

Viveksg ..i get the same error...ur solution does not work

viveksg

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

aescnt

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. :)

That does not work either....i tried this and still i get the error window.parent.frame.content is null or not an object.

if (CChanged || EChanged)
{
Response.Write("<script>window.parent.frames['content'].location='../Welcome.aspx';</script>");
}

where content is the name of the frame where all pages are displayed...urgent help wud be appreciated ..thanks

i also tried
opener.frames['content'].location='../Welcome.aspx'
but same error

aescnt

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.

but if i debug it ....i breaks at window.parent.frames['content'].location and gives the error.

aescnt

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?

actually its a pop up window...in where if EChanged or Cchanged then the parent page content frame should be redirected to welcom.aspx

aescnt

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?
