    I cannot get this to bind for some reason. I have attached the Fiddler response JSON data as evidence that it is coming in.

    <div class="k-content">
        <div id="listView"></div>
    </div>


    <script>
        $(document).ready(function() {


            var sharedDataSource = new kendo.data.DataSource({
                transport: {
                    type: "odata",
                    read: {
                        url: "DataService" + "/Events()?$filter=(((StartDate le datetime'2012-09-14') and (EndDate ge datetime'2012-09-14')) or ((StartDate le datetime'2012-09-21') and (EndDate ge datetime'2012-09-21'))) or (((((StartDate ge datetime'2012-09-14') and (EndDate le datetime'2012-09-21')) or ((StartDate le datetime'2012-09-14') and (EndDate ge datetime'2012-09-21'))) and (not Inactive)) and Viewable)",
                        contentType: "application/json; charset=utf-8",
                        type: "GET",
                        dataType: "jsonp",
                        data: {
                            Accept: "application/json"
                        }                   
                    }
                }
                ,
                pageSize: 12
            });

            $("#listView").kendoListView({
                dataSource: sharedDataSource,
                template: "<li>${Title}</li>"
            });
        });
    </script>

    Hi Benjamin,


    We cannot be sure what exactly is going wrong. The dataSource is configured for JSONP but from the response it's not getting clear if you are actually returning JSON or JSONP.

    Please provide more information about what data you are returning from your DataService or prepare example where the issue is reproduced - hopefully this will help us pinpoint the exact reason for this behaviour.

    I'm not sure what is happening now, but JSONP returns xml not JSON and when I change the Datatype to json then it will not even bother trying to get the data according to Fiddler! How would you debug this?

    Hi, not sure if anone is still having this problem but I finally worked out why my json wasn't binding with the listview.

    try adding JsonRequestBehavior.AllowGet to your return i.e. return Json(result, JsonRequestBehavior.AllowGet);
