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.
<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">
