    I am trying to use the HTML5 viewer with the following MVC code. 

    @(Html.TelerikReporting().ReportViewer()

               .Id("reportViewer1")
               .ServiceUrl("/api/reports")
               .TemplateUrl("/TelerikReports/Html5/ReportViewer/templates/telerikReportViewerTemplate-9.1.15.731.html")
               .ReportSource(new TypeReportSource() { TypeName = "MyApp.TelerikReports.MonthlySales, MyApp.Reports" })            
               .ViewMode(ViewMode.Interactive)
               .ScaleMode(ScaleMode.Specific)
               .Scale(1.0)
               .PersistSession(false)
               .Deferred()
        )

     

    I don't get any errors but the viewer renders as totally blank, no HTML is generated. What is most likely reason for this?

    I found a StackOverflow question with exactly the same problem, but no answer.

    Hi Craig,

    Most probably there is a hidden error. Thus my suggestion is to check the requests with tool like Fiddler.

    Give it a try and if you need additional assistance please send us the Fiddler log.

    I did try that and didn't see any errors. In fact it didn't even make any server requests at all.

    Hi Craig,

    How did you add the viewer? Did you use the dedicated item template as elaborated in  How To: Use HTML5 ASP.NET MVC Report Viewer in an application help article?

    Check out the Manual Setup help article to make sure that your project and viewer page are correctly configured.

    The demos that came with the Telerik Reporting installation have a running MVC demo, consider examining it.

    I have just started using the Javascript version directly and it seems to work now. Only problem now is the styling is broken on the preview, see attachment.

    Hi Craig,

    This looks like a missing CSS. Which version of Telerik Reporting you utilize? Currently all the CSS dependencies are served as resources by the REST service. Thus consider checking the requests with Fiddler.

    Looking in Fiddler no CSS resources are served. What should I be looking for and what could cause them not to be served?

    I manually included all the resources and font awesome and it seems to work now.
