RegisterStartupScript doesn't work in a aspx page containing a frameset

I have an aspx page which contains a frameset.

I want to set the location.href of the frames dynamically using javascript
created in the Page_Load of the frameset using RegisterStartupScript, but
the registered script doesn't appear to run. Is there some reason why
RegisterStartupScript won't work in a aspx page containing a frameset?

When you view the html source of that frameset page as it was
received by the browser, do you see the javascript there?

Just a wild guess: will javascript work in a frameset page? (I expect
it does, but you never know ...)

Thank you for the response.

I know that javascript works in a frameset page.

The problem is that when I attempt to insert javascript using
RegisterStartupScript in a frameset page the javascript is not created.

Thanks for looking at this for me. I expect I am overlooking something, but
I can't imagine what. It seems simple, but I can't think of anything else
to try.

I simplified it by creating a frameset with one frame containing a page.

The frameset uses RegisterStartupScript to insert javascript, but the
javascript doesn't get inserted.

The page which is the source of the frame uses identical code with
RegisterStartupScript to insert javascript which does work.

I also included some javascript hard coded in the frameset to verify that
javascript works in the frameset, and it does.

Thanks
Bill

----------------------------------
Here is the frameset page design - just a frameset with one frame. There is
a bit of javascript to verify that javascript works.

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Frameset1.aspx.vb"
Inherits="testing_Frameset1" %>

----------------------------------
Here is the Code Behind of the frameset page:
----------------------------------

Partial Class testing_Frameset1

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load

Dim csm As ClientScriptManager = Page.ClientScript
sScript = "<script language=javascript>" + sScript + "</script>"
csm.RegisterStartupScript(Me.GetType, "testFS", sScript)
End Sub
End Class



----------------------------------
Here is the Code Behind of the source page for a frame:
----------------------------------

Partial Class testing_Frameset1Frame1

I would also set the XHTML doctype to frameset, instead of
transitional. I believe you are supposed to do that when using frames.

The frameset uses RegisterStartupScript to insert javascript, but the
javascript doesn't get inserted.

The page which is the source of the frame uses identical code with
RegisterStartupScript to insert javascript which does work.

Script that was registered by RegisterStartupScript method is rendered
while form renders. No form - no script.
Try this (code in C#, I guess you will understand):

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<%= GetScript() %>
</head>
<FRAMESET id=testFS cols=100% frameBorder=0 frameSpacing=0 >
<FRAME name=testFr1 id=testFr1 noResize src="Frameset1Frame1.aspx"
scrolling=no>
</FRAMESET>
</html>

Add protected function that returns string value in the codebehind
file:

protected string GetScript()
{
string script = "<script type='text/javascript'> alert('Test
Frameset 1'); </script>";
return script;
}

I'll do that.

Apparently, however, RegisterStartupScript won't work in frameset pages
because there is no <form> tag, according to the post from "marss".

Thanks!
Bill
