Try to load only events

[Joris]

 Hi,

 A small problem I encountered when I switch to OData-v4 with scheduler.

I try to filter only the events that are visible in the scheduler control.

I Looks like to me that the parameterMap function is incorrect if the datasource is of type "odata-v4".

Found something like this kendo.data.transports.odata.parameterMap(options, type), but I'm still don't know how to add extra

filters. See code example for what I try to accomplish.

var schedulerDs = new kendo.data.SchedulerDataSource({
                type: "odata-v4",
                serverFiltering: true,
                transport: {
                    read: {
                        url: function() {
                            return "../odata/SchedulerEvents";
                        },
                        dataType: "json"
                    },

                    parameterMap: function (options, operation) {

                        if (operation === "read") {
                            var result = {
                                start: scope.schedularVar.view().startDate(),
                                end: scope.schedularVar.view().endDate()
                            }

                            return kendo.stringify(result);
                        }

                        return kendo.stringify(options);
                    }
                }

Hi Joris,

Please note that the build-in "odata-v4" dataSource type already have "parameterMap" function defined and specifying another one in the dataSource configuration is not supported out of the box. Possible solution is to use regular dataSource with "parameterMap" function that first calls the "odata-v4" "parameterMap" and then includes the desired additional parameters to the generated result, however such solutions falls outside the scope of our support service as it covers the build-in functionality of the controls only.
