HTML5 viewer passing parameters

[Stephen]

I'm having difficulty passing parameters to my reports using the MVC helper. The viewer loads the report correctly, but I'm not sure why it wont accept my passed values. I have an int and string to pass, I'm currently trying:

@{
    var report = new UriReportSource() { Uri = "Report.trdx" };
    report.Parameters.Add(new Telerik.Reporting.Parameter("UserId", Model.UserId));
    report.Parameters.Add(new Telerik.Reporting.Parameter("UserName", Model.UserName));
}

@(Html.TelerikReporting().ReportViewer()
           .Id("reportViewer1")
           .ServiceUrl("/api/reports/")
           .TemplateUrl("/ReportViewer/templates/telerikReportViewerTemplate.html")
               .ReportSource(report)
           .ViewMode(ViewModes.INTERACTIVE)
           .ScaleMode(ScaleModes.SPECIFIC)
           .Scale(1.0)
           .PersistSession(true)
        )

This is my first attempt as using the standalone designer, but I setup my parameters in the same fashion as previous reports. I keep getting "not all parameters have valid values". Attached an image with my current parameter setup.

Hi, Make sure that the Model properties are available. Try to with static values instead of the model.

Thanks for the reply. I'm really needing this to work. I tried it with static values as you mentioned, but I still get the same result. The UriReportSource does seem to load correctly, when I'm in debug mode I can see the object with the json forming correctly in the parameters. I'm thinking the problem is with the trdx report, or perhaps the serviceurl, which I honestly don't understand completely yet. I have the report setup the same way I did in the internal project, so I'm not sure what I'm missing. I wanted to try and use the internal report to compare, but I can't find any examples of using the helper with an internally built report.

Hello Stephen,

If all parameters were set, most probably the problem lies in the Newtonsoft.Json.dll. Your problematic project most probably references the GAC version of Newtonsoft. In order to fix check if Newtonsoft is still installed in the GAC and remove it if so. For a quick fix just delete the Newtonsoft reference from your project and add it using nuget.

Let us know if you need any further help.

Hi Yan,

Please test to set the persistSession option to false, to cease the preserving of the report between requests. Then verify that Newtonsoft.Json.dll is not installed in the machine's GAC, and update its reference to the latest available through Nuget.
