HTML5 Report viewer not accepting parameters

[Donald]

When I create a report viewer, I pass in the parameters, but the report still uses the default parameters. Also when I expand a group to show details it resets back to the default parameters. I am using customer parameters.


    $(function () {


        $("#reportViewer1")
            .telerik_ReportViewer({
                serviceUrl: "/api/TelerikReports/",
                templateUrl: '/Content/Telerik/Report/telerikReportViewerTemplate.html',
                reportSource: {
                    report: "SomeReportType",
                    parameters: {
                        StartDate: $('#StartDate').data("kendoDatePicker").value(),
                        EndDate: $('#EndDate').data("kendoDatePicker").value(),
                        DC: $('#Dcs').data("kendoComboBox").value()
                    }
                }
            });
    })


        function ShowReport() {

            var viewer = $("#reportViewer1").data("telerik_ReportViewer");

            
            viewer.reportSource({
                report: viewer.reportSource().report,
                parameters: {
                    StartDate: $('#StartDate').data("kendoDatePicker").value(),
                    EndDate: $('#EndDate').data("kendoDatePicker").value(),
                    DC: $('#Dcs').data("kendoComboBox").value()
                }
            });
            viewer.refreshReport();
        }

Update: It also doesn't seem to work using the built in parameter editors.

OK I figured this out, needed to update to the latest version of Newtonsoft.json aka json.net

This fixed another issue, when expanding groups it would show the report with the default parameters.
