Retrieving Json from Controller Action

[Varghese]

I'm using the kendoChart to display the json result from a controller action. The contoller action is getting called, but the page gives an error after that which is shown at the bottom of this message. I tried to catch the dataBound event to see what is happening. The error is happening even before the event, so can't catch it.

An example or help appreciated for this problem.

Controller Action:

...
return Json(itemCount, JsonRequestBehavior.AllowGet);

Script:

$("#liveChart").kendoChart({
...
dataSource: new kendo.data.DataSource({
 transport: {
  read: {
   url: "/Charts/Orders/GetLiveOrdersCount",
   dataType: "json"
  }
 },
 schema: {
  data: "data"
 }
}),
...

Error:

SCRIPT5007: Unable to get value of the property 'length': object is null or undefined
kendo.all.min.js, line 11 character 46965

Hello Varghese,

I suspect that the following configuration is not valid:

schema: {
 data: "data"
}

Does the data field of the returned JSON have actual data?

All the best,

Thanks. I removed "data" from the schema and it worked fine.
