Hide "One or more parameters are not set or have invalid values." message

Hello,
I need to open from a SL4 application a report passing 2 parameters (I open the report using the SL reportviewer inside a RadWindow), I load the report calling a method Load that's got the following code :

private void Load(int u_rapporto, DateTime date)
      {
          if (u_rapporto != 0)
          {
              reportViewer.Height = double.NaN;
              var reportViewerModel = reportViewer.DataContext as ReportViewerModel;

              Telerik.Reporting.Service.Parameter paramRapporto = new Telerik.Reporting.Service.Parameter();
              paramRapporto.Name = "Rapporto";
              paramRapporto.Type = typeof(int).FullName;
              paramRapporto.Value = u_rapporto;

              Telerik.Reporting.Service.Parameter paramData = new Telerik.Reporting.Service.Parameter();
              paramData.Name = "Data";
              paramData.Type = typeof(DateTime).FullName;
              paramData.Value = date;

              List<Telerik.Reporting.Service.Parameter> lst = new List<Telerik.Reporting.Service.Parameter>();
              lst.Add(paramRapporto);
              lst.Add(paramData);

              if (reportViewerModel.Parameters != null)
              {
                  reportViewerModel.Parameters.Clear();


                  reportViewerModel.Parameters.Add(paramRapporto);
                  reportViewerModel.Parameters.Add(paramData);

                  reportViewerModel.ApplyReportParametersCommand.Execute(null);
              }
              else
              {
                  reportViewerModel.Parameters = lst;
                  reportViewerModel.ApplyReportParametersCommand.Execute(null);

              }
          }
          else
          {
              reportViewer.Height = 0;
          }
      }

this works but due to transmission time it shows for some seconds a message "One or more parameters are not set or have invalid values." This it's due to the fact that when the radwindow load it  calls the webservice...is there a way of changing the text or to hide it?
Thanks in advance

Hi Paolo,

There is no direct way to influence the report from the Silverlight client as it resides on the server and that is why you're currently bound to use the report parameters to set the values. We have plans to provide report definition in Silverlight so you would be able to pass the values directly without need for the service i.e. there would be no delay and if everything goes well, we might be able to release this functionality for the Q3 release this year.
For the time being, the only way to avoid this message would be if you have predefined default values for the report parameters.

Hello Steve,
thanks for your answer , I've fixed using the reportfactory and in this way I pass the parameters in the

reportViewer_RenderBegin, works like a charm.... one last question, does Telerik Reporting WebService supports net.tcp transport layer?
Thanks
Paolo

Hi Paolo,

First to note that our report service is not a webservice but a WCF service. As such it supports all transport including net.tcp and this is unrelated to how Telerik Reporting works. More information is available in the Net.TCP Port Sharing MSDN article.
