Looks like you posted code but removed the problematic sections ;)

Is there something wrong with your JavaScript method that might be causing the problem?

Have you tried using JavaScript debugger tools (like the ones that come built into IE8 or using FireBug for FireFox)?

Does the event handler work when the page gets posted back eventually. Looks like the AsyncPostBackTr igger both say linkbutton1
