    Hi Gang,

    I've implemented the solution documented on one of your blog to load on demand the RadComboBox with a MVC JSON request. 

    I'm having a hard time trying to figure out if and how I can group entries server side (or even on the client).

    Any help would be greatly appreciated :)

    Regards,

    Hello Laurent Fabre,

    I guess that by grouping you mean using separator items as shown here. If yes this can be achieved in mvc as well:
    1. On the server side you need to set a custom attribute of the items which should be separators:
      item.Attributes["separator"] = true;
    2. On client side use the OnClientItemDataBound event to make the item a separator:
      function onItemDataBound(sender, args)
      {
            var item = args.get_item();
            if (item.get_attributes().getAttribute("separator"))
            {
                   item.set_isSeparator(true);
            }

      }
