Prevent user from collapsing any items

[Kevin]

Is there an option for the panel bar such that all items will be expanded and the user cannot collapse any of them?

Hello Kevin,

Try the following javascript.
JS:

<script type="text/javascript">
function onClientItemClicking(sender, eventArgs)
{
 var item = eventArgs.get_item();
 if (item.get_expanded())
 {
  eventArgs.set_cancel(true);
 }
}
</script>
