PDF and Content-disposition filename

10-06-2005, 11:30 AM

I've read the threads about this issue and haven't seen a solution that works for us. Any new ideas?

Issue: When using PDFExport to create a PDF stream which is then sent to a browser window via

Response.Clear();

Response.ContentType = "application/pdf";

Response.AddHeader("Content-disposition","inline");

Response.BinaryWrite(rptStream.ToArray());

Response.End();there doesn't seem to be a way to set the default filename that shows up when the user chooses to save a

copy in Adobe Reader 7's browser plug-in. Yes, I tried adding filename=whatnot.pdf to my content-disposition header, and about a million other things involving change the URL of the page to have a dummy

piece which included whatnot.pdf. The closest I came was when I add a dummy piece of the URL that had/whatnot.pdf, the default save name had *all* of the URL up to and including /whatnot.pdf, with various

characters replaced by underscores.

As far as we know, there isn't a solution that works 100% of the time when streaming the reports using the

response object. The only sure way is to export to a file and redirect the user to that file on the webserver.

The following is almost verbatim from the samples distributed with Active Reports, plus the added file name,

this works 100% of the time for me in MSIE & FireFox:

Private Sub lnkExportPDF_Click( ByVal sender As System.Object, ByVal e AsSystem.EventArgs) Handles lnkExportPDF.Click Dim rpt As ActiveReport = GetReport() Try rpt.Run( False) Catch eRunReport As DataDynamics.ActiveReports.ReportException ' Failure running report, just report the error to the user: Response.Clear() Response.Write("Error running report:") Response.Write(eRunReport.ToString()) Return End Try Dim pdf As New DataDynamics.ActiveReports.Export.Pdf.PdfExport



Dim memStream As New System.IO.MemoryStream pdf.Export(rpt.Document, memStream) Response.Buffer = True Response.ClearContent() Response.ClearHeaders() Response.ContentType = "application/pdf" Response.AddHeader("content-disposition", "attachment;filename=" & strFileName &".pdf") Response.BinaryWrite(memStream.ToArray()) Response.End() End Sub

Had tabled this one for a while but it's coming back on me as important again. The solution presented in the

last post pops up a box asking me if I want to open or save or cancel, due to the disposition of attachment. I

need to use inline, and the filename doesn't do anything with that option.

I have a problem with the filename in Firefox. I have the following code in a common class which is exactly

like the above code in VB:

public static void ExportToPDF(PdfExport exPDF, Document objDoc, string pdfFileName){

MemoryStream m_stream = new MemoryStream(); exPDF.Export(objDoc,m_stream);

HttpContext.Current.Response.Buffer = true; HttpContext.Current.Response.ClearContent(); HttpContext.Current.Response.ClearHeaders();

HttpContext.Current.Response.ContentType = "application/pdf"; HttpContext.Current.Response.AddHeader("content-disposition","attachment;filename=" + pdfFileName +

".pdf"); HttpContext.Current.Response.BinaryWrite(m_stream.ToArray());

HttpContext.Current.Response.End();}

My report title is "GP2 Performance Report". In IE, the report filename defaults to "GP2 Performance

Report.pdf", while in Firefox it simply defaults to "GP2" without the rest of the filename or extension.

Any ideas on why it might do that?

As far as not popping up the box asking you where you want to save it, replace the attachment line abovewith this:

HttpContext.Current.Response.AddHeader("content-disposition","inline;filename=" + pdfFileName + ".pdf");

Any other ideas on why the filename doesn't appear correctly in Firefox?



Thanks,

Greg


05-03-2006, 4:31 PM I'm curious if the space in the string is causing the glitch in firefox.

You are correct. I changed the name to GP2_Performance_Report and it preserved the complete filenameand extension.

Odd.

Thanks,Greg

Except when using inline, filename doesn't do anything.


05-09-2006, 8:49 AM I beg to differ. I can pass a different name to the pdfFileName and that name shows up in the Save As dialog

box when I save it.

Not me...in both IE and FF using Reader 7 plugins to both browsers the save as shows the name of the webpage as the default save name, no matter what is in the filename part of the content-disposition.
