How to get the value from an object from args.getDataKeyValue

Question

Now suppose CompanyName is a object and I want to get one field's value from args.getDataKeyValue("CompanyName"). Is this doable?

       function RowSelected(sender, args)
        {
            document.getElementById("<%= Label1.ClientID %>").innerHTML =
             "<b>CustomerID: </b>" + args.getDataKeyValue("CustomerID") +
             "<br />" +
             "<b>CompanyName: </b>" + args.getDataKeyValue("CompanyName");
        }
