<Object> Is undefined

Sam Samnah

I posted this during the weekend and I think it was missed so I am posting
it again. I'm in real big trouble with this and need help desperately. Any
suggestions will be met with unbelievable gratitude.
I don't know why but on the outputed page the dialog helper id is not
recognized or is "undefined" Can someone tell suggest what I am doing
wrong? I've been going over this goodness knows how many times and I can't
figure it out. The Object is set on the page properly but is not recognized
in the javascript. Some one please help.

Below is the code.

Thank you in advance,

Sam I am-

protected override void OnLoad(EventArgs e)

{

base.OnLoad (e);

if(!Page.IsClientScriptBlockRegistered("startup"))

{

StringBuilder jsload=new StringBuilder();

jsload.Append(@"<script language='javascript' type='text/javascript'>" +
"\n");

jsload.Append(@"window.onload=doInit;" + "\n");

jsload.Append(@"function doInit()" + "\n");

jsload.Append(@"{" + "\n");

string CMSUpReg=jsload.ToString();

}

}

This is the where the object is rendered

Hi Sam:

It might be easier to debug if you did a View -> Source on the page
and posted the resulting JavaScript. I'm assuming this is an error
that occurs in the java script itself?

It looks like a JS error, so you will have to render the page and pull the
JavaScript to see what is or is not being loaded. Walk through the JavaScript
rendered, line by line, and see if you can spot the error.

A second suggestion is step through the code line by line and look at what
variables are set. You might see a mistake in your thinking here.

It is increasingly hard to determine errors when part of your code is behind
the scenes (server code) and part is in front (client code) as the error can
be on either side.
