jquery selector doesn't check/uncheck all checkboxes from ASP.NET checkboxlist

Posted on 2011-02-26

I have a .NET form with two links (select all / none) that should check / uncheck all the checkboxes from a checkboxlist. Unfortunately, there's a bug in my selector and the checkboxes remain unchanged. My source is below.

Can someone tell me where my error is?

Thanks in advance.
