I'm trying to use dnnConfirm on a linkbutton in a panel that is initially hidden.  The panel is set to visible in the ascx file and is hidden in the code behind when the control is loaded. Depending on the user's actions, the linkbutton may be displayed in the code behind.  If it is displayed and clicked, dnnConfirm should be invoked.  The code works fine if the linkbutton is never hidden by server-side code.  However, once the linkbutton is hidden and then re-displayed, dnnConfirm no longer works.  What am I missing?
Thanks.

All jquery actions work by binding themselves to elements in the current visible page domain.  

When an element is 'hidden' by server side code it moves out of scope
 - or in other words the elements in question may no longer be visible to the client page domain.

So even though the code to bind dnnalert may be on your page - and appear to fire - it is not actually
binding when the panel is hidden.

In this case - you would need to look at where you are doing the binding code - that javascript side code.  
And make sure that it rebinds correctly each time the page is refreshed.

Thanks Wes.  I pretty much knew that was the situation, but was hoping for a magic bullet to make it work.  The jquery code was already outside of any panels being hidden was wrapped in document.ready.

The solution was to replace the $(document).ready(function() { with Sys.Application.add_load(function() { which runs on all postbacks and rebinds the controls once they're visible.
