Programmatically download a file as a pdf file

Question

Hello!

I have a web application that generates documents as rtf files. The user can download these files from a webpage by clicking on a link to them.

I would like the files to be automatically downloaded as PDF files and not as RTF files.

How could I do that?

Thank you.

You need to read and process your RTF files in C#  unfortunately there is no native .NET way how to convert that content to PDF format so you need to create a PDF file in C# yourself . For example this is one of the simplest solutions to achieve the required conversion and also export that resulting PDF file to ASP.NET's client : var document = DocumentModel .Load( Sample.rtf ); document.Save( this .Response Sample.pdf ); The code uses this .NET library for Word documents processing .

Hi This you can do by using this code: 1. Add reference for CrystalDecisions.CrystalReports.Engine. 2. Add assembly in your page like this Namespace=CrystalDecisions.Web TagPrefix=CR %> 3. Add CrystalReportViewer in you page deign like this 4. Create a Crystal Report by using a view e.g. vw_VendorList. VB.Net Code: Dim Rpt As New ReportDocument Rpt.Load(Server.MapPath(abc.rpt)) Dim ds As New Data.DataSet Dim dt As New SqlDataAdapter(Select * from VW_VendorList ConnString) dt.Fill(ds VW_VendorList) Rpt.SetDataSource(ds) CRV.ReportSource = Rpt Rpt.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat Response True Vendor List Report) After running this code crystal report file will be exported in the form of Pdf. Hope it will help.

It seems difficult to download the file as PDF automatically. Maybe you can try to convert RTF to PDF after downloading?

Dear Kamal Thank you for your answer. However the documents are generated as rtf documents. What I want to do is for them to be converted to pdf when the user clicks download. Is that possible? How could I do it? Thank you.

VB.Net Dim FileName As String = Path.GetFileName(FullFileName) //Function provides file path Response.ContentType = application/octet-stream Response.AddHeader(Content-Disposition attachment; filename= & FileName) Response.WriteFile(FullFileName) Response.[End]() C# .NET string FileName = Path.GetFileName(FullFileName); //Function provides file path Response.ContentType = application/octet-stream; Response.AddHeader(Content-Disposition attachment; filename= + FileName); Response.WriteFile(FullFileName); Response.End(); Please mark it as Accept if it helps..
