How to specifiy proxy settings for SSRS Winforms Control

I am using the 开发者_StackOverflowSSRS WinForms client control to display reports in an app. User's behind proxies are getting a 407 (proxy authentication) error. How do I specify proxy settings for the request? i.e. proxy server, username & password. I was expecting it to be similar to the HttpRequest and WebProxy.

This is helpful C# Connecting Through Proxy however I need to specify proxy settings on a per SSRS request basis.

Any ideas?

Thanks.

You can specify the proxy settings by using reporting web services.

• Add the reporting web reference to your project. The URL of the web service is :

http://servername/ReportServer/ReportExecution2005.asmx

• In the code calling the web service.

  byte[] report = null;

          //create an instance of the reporting service web reference
          var reportReference = new ReportExecutionService();
  
          <strong>//Set your proxy settings
           reportReference.Proxy = new WebProxy("address:port");
  
  
          //create a credential that will be used to authenticate again the
  

  reporting services var credential = new NetworkCredential("username", "password", "domainName");

          reportReference.Credentials =
  

  credential;

          reportReference.PreAuthenticate =
  

  true;

          //the virtual path to the report
          string virtualPath = "/Folder/ReportName";
  

  
  

          //Specify the device info
          string deviceInfo =
              "<DeviceInfo><Toolbar>False</Toolbar><Parameters>False</Parameters><DocMap>True</DocMap><Zoom>100</Zoom></DeviceInfo>";
  
          //Create an array of parameters, for example our report needs 2 parameters
          var parameters = new ParameterValue[2];
  
          //Specify the value for the parameter
          var startDateParameter = new ParameterValue();
          startDateParameter.Name = "StartDate";
          startDateParameter.Value = "01/01/2008";
  
          parameters[0] = startDateParameter;
  
          var endDateParameter = new ParameterValue();
          endDateParameter.Name = "EndDate";
          endDateParameter.Value = "31/12/2008";
  
          parameters[1] = endDateParameter;
  
          //Create variables for the remainder of the parameters
  
          string extension = string.Empty;
  
          ExecutionHeader executionHeader = null;
  
          reportReference.ExecutionHeaderValue =
  

  executionHeader;

          reportReference.LoadReport(virtualPath,
  

  null);

          reportReference.SetExecutionParameters(parameters,
  

  "en-AU");

          try
          {
              //Execute the report
              string[] streamIDs;
              Warning[] warning = null;
              string encoding;
              string mimeType;
              string format = "PDF";
  
  
              <strong>//Execute the report
              report = reportReference.Render(format,
  

  deviceInfo, out extension, out mimeType, out encoding, out warning, out streamIDs);

              using (var fileStream = new FileStream("myReport.PDF", FileMode.Create))
              {
                  fileStream.Write(report, 0,
  

  report.Length);

                  fileStream.Close();
              }
  

  > Process.Start("myReport.pdf");

          }
          catch (SoapException exception)
          {
  

  
  }
