HOW-TO
Prevent a RadPanelBar item from collapsing

SOLUTION
A common way to prevent a RadPanelBar item from collapsing is hooking on the OnClientItemClicking client side event of RadPanelBar and cancel the event when the item is about to be collapsed.

<script type="text/javascript"> 
function onClientItemClicking(sender, eventArgs) 
{ 
    var item = eventArgs.get_item(); 
    if (item.get_expanded()) 
    { 
        eventArgs.set_cancel(true); 
    } 
} 
</script> 
... 
<telerik:RadPanelBar ID="RadPanelBar1" OnClientItemClicking="onClientItemClicking" runat="server"> 

Alternatively, you can set the PreventCollapse property of the RadPanelItem to False.
