    I have been working on this for a while and it simply doesn't work.  I set my reportSource as follows (as specified in the TR-Q1 2015 documentation):

    self.loadViewer = function () {
        reportSource: self.reportSource(),
        serviceUrl: self.reportSettings.serviceUrl,
        templateUrl: self.reportSettings.templateUrl,
        viewMode: self.reportSettings.viewMode,
        scaleMode: self.reportSettings.scaleMode,
        scale: self.reportSettings.scale,
        ready: function () {
            self.reportViewer = this;

    self.refreshReport = function () {
        if (self.reportViewer) {

    self.compositionComplete = function () {

    I have tried to set the reportSource in different ways still I see that the viewer is not passing the correct params but those used while in design.  Can you please provide an example that works for MVVM (I am using Durandal).

    My recent test looks like:

    self.refreshReport = function () {
    var viewer = $('#reportWrapper').data('telerik_ReportViewer');
    if (viewer) {
    var source = self.reportSource();
        parameters: {
                      CustomerId: self.customerId,
                      OptionNo: '0'

    Any idea what is wrong?

    Hi Eduardo,

    The attached demo project illustrates a simplified usage of MVVM and the HTML5 Report Viewer.

    Please use the browser's console or Fiddler to trace the sent requests, their URLs, content and response statuses. If you use Fiddler, this information will be listed in Fiddler - Inspectors - Request/Response - Raw tabs.

    Through the browser's console you can debug what values are passed on creating and refreshing the viewer's object.
