Hello,
I have same javascript that uses $find which was working fine in Chrome / IE and I just tested it in Firefox 4 however $find() is returning null. Here is the line of javascript code:
var tab = $find("<%=LookupTabs.ClientID%>").get_selectedTab();
Firefox is giving this error:
Error: $find("ctl00_ctl00_mainContent_pretrialContent_LookupTabs") is null
Source File: http://localhost:6444/CJIS/Pretrial/Lookup.aspx?NewInterview=2034111
Line: 164
However, again, it works fine in IE and Chrome.
Any suggestions? Thanks!

Hello Chris,
The problem you experience is really strange.
Could you please send us a sample project which demonstrates the issue to examine it locally?

Hello, I had the same problem and I found out that there was a previous JavaScript error in FireFox but not in IE or Chrome.
Once JavaScript error in FireFox was solved, function $find worked again as usual.
I hope it helps.

I upgraded a project from .NET 2.0 to .NET 3.5 - and my $find statements were returning null as well - in IE as well as Mozilla
different behavior
in the item selected event handler function the finds for 2 Rad textboxes:
if the function was called from another function which itself was an event handler for a button they returned null
if it was called from the user actually selecting a row it worked fine

Hi Marianne,
Can you please provide some markup and the javascript event handler that you are using so we can inspect it locally and determine why you are not able to find the needed controls/element?

I was mixing RadAjaxManager with RadUpdatePanels
the problem is bigger than just not finding testboxes on the client and I opened a ticket which is being worked on
