Hi all,

"Only export to PDF format from ReportViewer add-in"...Is this possible? Right now the reportviewer has two options of exporting the current report-Excel and PDF...Is it possible to have PDF as the only option. I don't want my clients to export it to excel.

Thanks in advance....

As far as I know you can't remove excel export from ReportViewer.

You can only hide export control and only allow user to print the page.

----------------------------

Or you can use a button outside the reportviewer and use the local report's render function to export to pdf only.

----------------------------

I got this code. but I don't want to save. I want to Export the  Report into  PDF and open directly but How?????.

string mimeType;    
        string encoding;     
        string fileNameExtension;     
        string[] streams;     
        Microsoft.Reporting.WebForms.Warning[] warnings;        byte[] pdfContent = ReportViewer1.LocalReport.Render("PDF", null, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
        //Creatr PDF file on disk    
        string pdfPath = @"C:\temp\reportBarcode.pdf";     
        System.IO.FileStream pdfFile = new System.IO.FileStream(pdfPath, System.IO.FileMode.Create);     
        pdfFile.Write(pdfContent, 0, pdfContent.Length);     
        pdfFile.Close();

----------------------------

Heres what I have.

private void saveRptAsBas(String s_rptType)
    {        
        Warning[] warnings;
        string[] streamids;
        string mimeType;
        string encoding;
        string extension;
        // string deviceInfo;
        DataSet ds = GetSalesDataFull();
        // This if() block may not be required for you
        // It just the nRows parameter in the report before exporting
        if ((s_rptType == "EXCEL") || (s_rptType == "PDF"))
        {
            ReportParameter param = new ReportParameter("nRows", ds.Tables[0].Rows.Count.ToString());
            this.ReportViewer2.LocalReport.SetParameters(new ReportParameter[] { param });
        }
        
        byte[] bytes = ReportViewer2.LocalReport.Render(
        s_rptType, null, out mimeType, out encoding, out extension,
        out streamids, out warnings);

        /*
        FileStream stream = File.OpenWrite(@"C:\Documents and Settings\michael.shorten\Local 
        Settings\Temp\sample.pdf");
        stream.Write(bytes, 0, bytes.Length);
        stream.Close();
        */

        Response.Buffer = true;
        Response.Clear();
        Response.ContentType = mimeType;
        Response.AddHeader("content-disposition", "attachment; filename=Report." + extension);
        Response.BinaryWrite(bytes);
        Response.Flush();
        Response.End();
    }
