Example - subscribe to the requestEnd event during initialization

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    read: {
      url: "https://demos.telerik.com/kendo-ui/service/products",
      dataType: "jsonp"
    }
  },
  requestEnd: function(e) {
    var response = e.response;
    var type = e.type;
/* The result can be observed in the DevTools(F12) console of the browser. */
    console.log(type); // displays "read"
/* The result can be observed in the DevTools(F12) console of the browser. */
    console.log(response.length); // displays "77"
  }
});
dataSource.fetch();
</script>

Example - subscribe to the requestEnd event to catch only read requests

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    read: {
      url: "https://demos.telerik.com/kendo-ui/service/products",
      dataType: "jsonp"
    }
  },
  requestEnd: function(e) {
    //check the "response" argument to skip the local operations
    if (e.type === "read" && e.response) {
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log("Current request is 'read'.");
    }
  }
});
dataSource.fetch();
</script>

Example - subscribe to the requestEnd event after initialization

<script>
function dataSource_requestEnd(e) {
  var response = e.response;
  var type = e.type;
/* The result can be observed in the DevTools(F12) console of the browser. */
  console.log(type); // displays "read"
/* The result can be observed in the DevTools(F12) console of the browser. */
  console.log(response.length); // displays "77"
}
var dataSource = new kendo.data.DataSource({
  transport: {
    read: {
      url: "https://demos.telerik.com/kendo-ui/service/products",
      dataType: "jsonp"
    }
  }
});
dataSource.bind("requestEnd", dataSource_requestEnd);
dataSource.fetch();
</script>

The requestEnd event does not hold information regarding any errors that occurred during the request. The error information is available as part of the error event.
