    Does the DS have any way for me to capture and handle jsonp errors?

    Is there a best practice?

    I've tried this, but nothing happens (no alerts)

    dataSource: new kendo.data.DataSource({
                        serverFiltering: true,
                        transport: {
                            read: {
                                url: function (e) {
                                    var value = $("#activityTypeBox").data("kendoDropDownList").value();
                                    if (value != "") {
                                        return "http://site/api/activities/getByType/id/" + value + "/format/jsonp"
                                dataType: "jsonp",
                                jsonpCallback: 'myCallback'
                            parameterMap: function (data, type) {
                        schema: {
                            errors: "error" // ex: twitter's response is { "error": "Invalid query" }
                        error: function (e) {
                            alert("Problem populating the curriculum db activities based on that type");

    Hi Steve,

     The error event of the data source relies on the error callback of jQuery.ajax. For some reason that callback is not invoked when using JSONP and the url is wrong. Here is a quick demo showing that: http://jsbin.com/ecofic/1/edit. This seems to be a known limitation.
