User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.9

In the last 1/3 of the page the section "Sample code in C#" has a "Show Code"
link.  When you click on this you get no response (i.e. it doesn't expand as it
should).  When viewing this in other browsers (IE 6, Konqueror and AFAICR Opera)
it works fine.  It complains about this javascript:

   if (eval(ref).style.display =='none')
//     (where ref = 'Structure')

The error given is "Structure" is not defined.

"Structure" is a TBODY HTML element with the ID defined as follows:
    <TBODY ID="Structure" style="DISPLAY:none">

Reproducible: Always
Steps to Reproduce:
1. Visit web page.
2. Click on "Show Code" link in Konqueror / IE 6.  Observe code is shown, then
3. Click on "Show Code" link in Mozilla Firefox 0.9 or other Mozilla browser and
observe that code is not shown and javascript error is logged in console.

Actual Results:  
"Show Code" didn't work - no text expanded.  Javascript error in console.

Expected Results:  
Text should have been expanded.

I have asked the owner's of this site repeatedly to change their pages but they
will not do it.  I have also observed this issue when debugging ASP.NET apps -
Microsoft themselves use this kind of code to show and hide text.  So this may
even affect most ASP.NET apps that provide this functionality.  Therefore this
is a serious issue that should be addressed ASAP.

NOTE: Although this may be an "ieism" as one response indicated...  this is not
a fault of the web site developer per se...  take a look at the top of this HTML
doc.  It indicates that the code was generated by Visual Studio (see code
snippet below).  I think that means that VS generated the code- and not the
user.  So, if this is not fixed in Mozilla it will have to be fixed by
Microsoft.  They probably don't care about changing it because they're
interesting in IE dominating the web anyway.  So, I think it is still important
that this behavior is changed in Mozilla.  Especially because Opera and
Konqueror support it.  It has become a defacto standard even if it isn't a W3C

The site works as expected.

This bug should be closed.
