Hi,

I am trying to implement Telerik Reporting in our Silverlight application, and I am having a problem connecting Telerik Report Services to a Silverlight Report Viewer.  In one solution I have a Windows Azure project running a Web Role that contains a WCF service (ReportService.svc) and a project with the Repors (ReportLibrary) as instructed on this video (http://tv.telerik.com/reporting/video/telerik-reporting-getting-started-with-silverlight-report-viewer), and on the other solution I have a Silverlight app with a Silverlight Report Viewer.  When I try to setup the Silverlight client I get an error. (see image attachment).

The XAML code looks like this on the client side.

<UserControl x:Class="ROPComposite.Report.Telerik_Report.TelerikReportView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:reportViewer="clr-namespace:Telerik.ReportViewer.Silverlight;assembly=Telerik.ReportViewer.Silverlight"
       
    xmlns:telerikNav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
    xmlns:telerikControls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
    xmlns:telerikPrimitives ="clr-namespace:Telerik.Windows.Controls.Primitives;assembly=Telerik.Windows.Controls"
    xmlns:telerikInput="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input">

    <Grid x:Name="LayoutRoot" Background="White">
        <reportViewer:ReportViewer x:Name="xReportViewer"
                                   ReportServiceUri="http://127.0.0.1:81/Service/ReportService.svc"
                                   Report="ReportLibrary.AllPatients, ReportLibrary,  Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
        </reportViewer:ReportViewer>
    </Grid>
</UserControl>

The configuration for the service looks like this on the server side.

        <behavior name="ReportServiceBehavior">
          <dataContractSerializer maxItemsInObjectGraph="10000000"/>
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
          <useRequestHeadersForMetadataAddress>
            <defaultPorts>
              <add scheme="http" port="81"/>
              <add scheme="https" port="444"/>
            </defaultPorts>
          </useRequestHeadersForMetadataAddress>
        </behavior>
...
      <endpointBehaviors>
        <behavior name="WebBehavior">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
...
      <service name="Telerik.Reporting.Service.ReportService" behaviorConfiguration="ReportServiceBehavior">
        <endpoint address="" binding="basicHttpBinding" contract="Telerik.Reporting.Service.IReportService">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <endpoint address="resources" binding="webHttpBinding" behaviorConfiguration="WebBehavior" contract="Telerik.Reporting.Service.IResourceService"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>

I know the Report works because I created an aspx page and I was able to see it using the Web Report Viewer, but not through WCF.

On the Reporting documentation ( http://www.telerik.com/help/reporting/silverlight-hosting-in-iis.html ) on how to Host a WCF Service for reports, I don't understand how Service class (ReportService.svc) knows what library the reports are.  Just by adding a reference to the library containing the reports, is that all I need to do?

I would appreciate all the help I can get.

Hi Deylo Woo,

The "NotFound" error usually indicates an invalid service url. If it is working on your local machine, make sure that the WCF service is hosted properly in IIS and you have deployed it correctly - see this thread. and verify that the ReportViewer.ReportServiceUri points to the correct location of the Telerik Reporting WCF Service. The easiest way to get started is to review carefully the Telerik Reporting Getting Started with the Silverlight Report Viewer video and use the provided Visual Studio Silverlight example solution as base.

Kind regards,
Steve

I suspected it was a WCF error.  The report service does not work on my local machine nor on Azure Cloud, however I have several other WCF services running well locally and when published to the cloud.  I better open a trouble ticket.  This is crucial to our app.

Thanks.
