Export C # reportviewer software control

Question

Does anyone know if you can programmatically save a report displayed in a reportviewer control in C #?

When the report is displayed, there are "Export to ..." buttons, and I would like to automate the save to PDF function.

Answer 1

You can do this using the ReportViewer Control (with the LocalReport.Render Method ), check out the "Send Report" example at http://www.gotreportviewer.com/

string _sPathFilePDF = String.Empty; String v_mimetype; String v_encoding; String v_filename_extension; String[] v_streamids; Microsoft.Reporting.WinForms.Warning[] warnings; string _sSuggestedName = String.Empty; Microsoft.Reporting.WinForms.ReportViewer reportViewer1; Microsoft.Reporting.WinForms.LocalReport objRDLC = new Microsoft.Reporting.WinForms.LocalReport(); reportViewer1.LocalReport.ReportEmbeddedResource = "reportViewer1.rdlc"; reportViewer1.LocalReport.DisplayName = _sSuggestedName; objRDLC.DataSources.Clear(); byte[] byteViewer = rptvFlightPlan.LocalReport.Render("PDF", null, out v_mimetype, out v_encoding, out v_filename_extension, out v_streamids, out warnings); SaveFileDialog saveFileDialog1 = new SaveFileDialog(); saveFileDialog1.Filter = "*PDF files (*.pdf)|*.pdf"; saveFileDialog1.FilterIndex = 2; saveFileDialog1.RestoreDirectory = true; saveFileDialog1.FileName = _sSuggestedName; if (saveFileDialog1.ShowDialog() == DialogResult.OK) { FileStream newFile = new FileStream(saveFileDialog1.FileName, FileMode.Create); newFile.Write(byteViewer, 0, byteViewer.Length); newFile.Close(); }

You cannot export to an event prior to reportviewer in web forms.
