The attach example Test.html does not work against my service. When monitored in Fiddler I cannot see the parameters being passed on to the call? Not sure what I'm missing this was taken from online API example.
Hi,
Report parameters can be passed on creating the viewer object through the reportSource object. If you need to update parameters values via custom UI, you can get the viewer object and update its reportSource - http://www.telerik.com/help/reporting/html5-report-viewer-howto-custom-parameters.html.
Please post any further technical questions through our support ticketing system or product forums.
