Multiline textbox is not a part of INPUT element group, rather it is a TEXTAREA tag. So you need to fetch this also.
For example-

JavaScript

var gridViewID = "<%=grdMenu.ClientID %>";
           var gridView = document.getElementById(gridViewID);
           var Menuitem = new Ncoretech.Business.Data.MenuType();
           var e = document.getElementById("<%= ddlRestaurantName.ClientID%>");
           var gridViewControls = gridView.getElementsByTagName("input");
           for (i = 0; i < gridViewControls.length; i++) {
               if (gridViewControls[i].id.search("txtNewMenuName") != "-1") {
                   Menuitem.MenuName = gridViewControls[i].value;
               }
           }
           gridViewControls = gridView.getElementsByTagName("textarea");
           for (i = 0; i < gridViewControls.length; i++) {
               if (gridViewControls[i].id.search("txtNewMenuDescription") != "-1") {
                   Menuitem.MenuDescription = gridViewControls[i].value;
               }
           }
           Menuitem.RestaurantIndex_Id = e.options[e.selectedIndex].value;
           if (Menuitem.MenuName == "") {
               alert("Item name has to be enter.");
               return false;
           }
           if (Menuitem.MenuDescription == "") {
               Menuitem.MenuDescription = "none";
           }

Hope this may help you out...
