Preventing a RadPanelBar PanelItem from collapsing

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.

ASP.NET

<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">
