Store option not working dgrid, works perfect with ondemandgrid - dojo

Question

I want to use store attribute of Dgrid, i am using below code to make dgrid table but somehow table doesn't get populated with rows.
<script src="dojo/dojo.js"
data-dojo-config="async: true"></script>
<script>
require(["dojo/_base/declare","dgrid/Grid","dgrid/Keyboard","dgrid/Selection","dgrid/editor","dgrid/extensions/DnD","dojo/dnd/Source", "dojo/store/Memory", "dojo/_base/lang"],
function (declare,Grid,Keyboard,Selection,editor,DnD, DnDSource, Memory, lang){
var store = new Memory({
data: [
{ id: 1, firstName: "Jeffrey", lastName: "Andrews", email: "jeffrey#madeupdomain.com" },
{ id: 2, firstName: "Jenny", lastName: "Saunders", email: "jenny#madeupdomain.com" },
]
});
var structure = [
{field: "lastName", label: "Last Name"},
{field: "firstName", label: "First Name"},
{field: "email", label: "EMail Address"}
];
var grid = new (declare([Grid, Selection, DnD]))({
store: store,
columns: structure
},
"gridtable");
grid.startup();
});
</script>
</head>
<div id="gridtable"></div>

Answer 1

The base List and Grid modules are not designed to be store-aware. Store awareness is usually inherited from _StoreMixin, which OnDemandList and the Pagination extension inherit.
It's also feasible to make your own extension of _StoreMixin; for example, one of the tutorials on dgrid.io walks through a very simple extension to render all data from a store at once.
