RadComboBox & JSON, Grouping options ?

[Laurent Fabre]

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);
         }
   
   }
