kendo ui grid not showing data - asp.net-mvc

Question

I am trying to get this basic kendo ui with expandable rows working:
<div id="grid"></div>
<script type="text/javascript">
$(function () {
$("#grid").kendoGrid({
columns: [
{
field: "ProductId",
title: "ProductId"
}
],
dataSource: {
type: "json",
transport: {
read: '#Url.Action("GetData1", "MockForms")'
}
},
height: 450,
sortable: true,
pageable: true,
detailTemplate: "<h2 style='background-color: yellow;'>Expanded!</h2>",
detailExpand: function (e) {
this.collapseRow(this.tbody.find(' > tr.k-master-row').not(e.masterRow));
}
});
});
</script>
The json is generated like this:
public ActionResult GetData1([DataSourceRequest] DataSourceRequest request)
{
var list = new List<Product>
{
new Product {ProductId = 1, ProductType = "SomeType 1", Name = "Name 1", Created = DateTime.UtcNow},
new Product {ProductId = 1, ProductType = "SomeType 2", Name = "Name 2", Created = DateTime.UtcNow},
new Product {ProductId = 1, ProductType = "SomeType 3", Name = "Name 3", Created = DateTime.UtcNow}
};
return Json(list.AsQueryable().ToDataSourceResult(request));
}
and seems to be send OK (according to firebug). However, nothing is bound (there are no javascript errors). Any ideas?
PS:
OnaBai's 2nd comment helped me to get this to work. I changed:
return Json(list.AsQueryable().ToDataSourceResult(request));
=>
return Json(list);
which produces this JSON:
[{"ProductId":1,"ProductType":"SomeType 1","Name":"Name 1","Created":"\/Date(1371022051570)\/"},{"ProductId":1,"ProductType":"SomeType 2","Name":"Name 2","Created":"\/Date(1371022051570)\/"},{"ProductId":1,"ProductType":"SomeType 3","Name":"Name 3","Created":"\/Date(1371022051570)\/"}]
Still I would like to use:
return Json(list.AsQueryable().ToDataSourceResult(request));
as this will eventually make paging and sorting easier. It currently produces:
{"Data":[{"ProductId":1,"ProductType":"SomeType 1","Name":"Name 1","Created":"\/Date(1371022186643)\/"},{"ProductId":1,"ProductType":"SomeType 2","Name":"Name 2","Created":"\/Date(1371022186648)\/"},{"ProductId":1,"ProductType":"SomeType 3","Name":"Name 3","Created":"\/Date(1371022186648)\/"}],"Total":3,"AggregateResults":null,"Errors":null}
I tried to use:
field: "Data.ProductId",
instead of:
field: "ProductId",
in the JavaScript code with no avail.

If you want to use ToDataSourceResult you should use the ASP.NET MVC wrappers. More info is available in the documentation: http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/ajax-binding
