ASP.net MVC - Telerik Reporting error => /api/reports/clients returns “Missing report name”

[N M Reddy]

I am new to Telerik Reporting & have started adding Report Viewer to my ASP.net MVC application. In runtime ReportViewer is displaying "Bad Request" & Fiddler is displaying below error message.

Message: POST /api/reports/clients/215829-979c/parameters HTTP/1.1 "Missing report name"

Can you please help me in this.

Report viewer code snippet:

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

Report Source in ViewModel

            var settings = new System.Xml.XmlReaderSettings();<br>            settings.IgnoreWhitespace = true;<br><br>            using (System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(System.Web.HttpContext.Current.Server.MapPath("~/Reports/Dashboard.trdx"), settings))<br>            {<br>                var xmlSerializer = new Telerik.Reporting.XmlSerialization.ReportXmlSerializer();<br><br>                var report = (Telerik.Reporting.Report)xmlSerializer.Deserialize(xmlReader);<br>                report.DataSource = this.SearchResult == null ? new List<EnquiryPoster>() : this.SearchResult;                <br><br>                this.ReportSource = new InstanceReportSource<br>                {                    <br>                    ReportDocument = report,<br>                };<br>            }

Hi Nm,

Based on the code snippets you pass InstanceReportSource to the viewer which we do not recommend. Please use TypeReportSource and bind the report using ObjectDataSource. For example take a look at the attached sample project.

I hope this information helps you.

We are using Kendo-Telerik Controls for our projects. Basically we are using ASP.NET MVC application and we consume the WCF services for our data access. When we try to use Telerik reports, we presumed like need to in corporate WepApi. Please advice us how to proceed further.

Hello Siva,

Please check the following forum thread elaborating on the HTML5 Report Viewer and Reporting REST service architecture, and the possible approach to supply data via data service or in custom resolver for the service: Using ObjectDataSource With Non-Static Methods?

On a side note for anyone concerned, you can use InstanceReportSource to display a report in the HTML5 Report Viewer. For the purpose you will need a custom report resolver where to instantiate the report on the server and wrap it in an InstanceReportSource.
