[Solved] Selectionmode = "Single" Not Working

[James]

Hello,

I have a RadListBox that is will only allow multiple selection. I have Selectionmode="Single" set but that does not work. I have also tried some Javascript with no luck. Obviously this is a bug but what can I do hear to get the selection mode to single.

Fixed. If your selectionmode is not working when set to selectionmode = "Single", call this javascript function on the "OnClientItemChecking" event:

function singleSelection(sender, args)
    {
        var item = args.get_item();
        var items = sender.get_items();
        var checked = item.get_checked();
        if (checked == false)
        {
            items.forEach(function (itm) { itm.set_checked(false); });
        }
    }
