I upgraded several RDL reports to RDLC; the reports were originally written in VS2005 and upgraded with VS2010. I'm using the report viewer in VS2010. The reports run without error, but don't return any data, although the parameters are visible in the report header. A test report developed in VS2010 runs. Is there some references available that enable me to edit the xml file to resolve this issue? Note that the obj references SlaveDataSet from intellisense, but when I don't get an error when I use DataSet1 as the rds.Name (SlaveDateSet errors): try { ReportDataSource rds = new ReportDataSource(); rds.Name = "DataSet1"; rds.Value = obj; this.rpvFlash.ProcessingMode = ProcessingMode.Local; this.rpvFlash.LocalReport.ReportEmbeddedResource = sReport; this.rpvFlash.LocalReport.DataSources.Add(rds); if (bHasParams == true) { ReportParameter[] rParam = new ReportParameter[2]; rParam[0] = new ReportParameter("Start", dtpStart.Value.ToShortDateString()); rParam[1] = new ReportParameter("End", dtpEnd.Value.ToShortDateString()); this.rpvFlash.LocalReport.SetParameters(rParam); } else { ReportParameter rParam = new ReportParameter(); rParam = new ReportParameter("Date", dtpEnd.Value.ToShortDateString()); this.rpvFlash.LocalReport.SetParameters(rParam); } //MessageBox.Show(this.rpvFlash.LocalReport.IsReadyForRendering.ToString()); this.rpvFlash.RefreshReport(); } catch (Exception ex) { MessageBox.Show(ex.Message); } Dan Slaby

Hi Dan, Could you please clear the DataSources first, and then add the rds to DataSources to check if the issue is solved? this.rpvFlash.LocalReport.ReportEmbeddedResource = sReport; this.rpvFlash.LocalReport.DataSources.Clear(); this.rpvFlash.LocalReport.DataSources.Add(rds); Thanks, Jin Chen Jin Chen - MSFT

Thanks for your suggestion, but it did not fix the issue. Do you have any other?Dan Slaby

Hi Dan, Could you please debug the application, and check if the dataset has data? Also, could you please try to add a textbox to the report, and use the expression =First(Fields!fieldname.Value, "dataset") to check if the data is passed in correctly. Thanks, Jin ChenJin Chen - MSFT

Apparently the probem is that the "DataSet1" that is embedded in the report is not the same as the "DataSet1" that was created in the application where the reports were copied. I don't see any xml files in the embedded windows reports that I can change guids. Is there a way to edit these reports and datasets to conform their guids? Dan Slaby Incidently, I copied the reports to VS2010 and am developing the application in VS2010. The Tablix Properties show the dataset name 'Dataset1' on the row containing the expresions from the Fields(DataSet1), but don't display data. The textbox using the expression =First(Fields!LGC.Value, 'DataSet1') doesn't return any data. the Fields in the category shows the message 'Report item is not linked to a dataset'. Are these typical issues trying to use the reportviewer in VS2010 with report conversions from RDL to RDLC? Incidently, I created another approach using the webbrowser in VS2010 and find that the parameters are ignored even when they are in the parameter string, and when the webbrowser opens it doesn't activate the calendar nor accepts input from the associate textboxes. Is this because the client side scripting does not work in the windows webbrowser?

I found the missing part, and added a function to fill obj with data before assigning it to rds.value.Dan Slaby
