Can PanelBar be collapsed for "SingleExpandedItem"?

[Ron]

Hi Guys,

     I have used PanelBar in my application.
     I am not able to collapse items if I used the following setting:
         

ExpandMode = PanelbarExpandMode..SingleExpandedItem;
   
     But it works on this setting:
         ExpandMode = PanelbarExpandMode.MultipleExpandedItems;

       is this by design?  RadPanelbar can't be collapsed if the Expandmode is SingleExpandedItem.

Thanks for your help,

Ron.

Hi Ron,

Please note that this behavior is by default; when you have ExpandMode="SingleExpandedItem" one header item will be always expanded. The expanded item will be closed upon clicking on other header item. If you want to be able to collapse a header item while clicking on it you will have to set the ExpandMode property to MultipleExpandedItems.

Still, you can use the follwoing JS on OnClientItemClicking client event:

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