How to set filename of pdf when downloading

[Matthias Wagner]

Hello,

at the moment the filename of a downloaded pdf-File is set to "undefined.pdf". We want to give this file a name.

I tried to set the filename in codebehind (PdfViewer.aspx.cs),  when I set the DocumentPath. Is this possible?

Alternatively i tried to set the filename in javascript after pressing the "download"-button.

Both attempts to set the filename werent successful.

Could you please show me in the attached project how to set the filename?

I would prefer the solution in code behind.

Thank you very much.

Matthias

We encountered the same issue (but in Blazor), is there any update?

Hi   DotCom , 

 

For ASP.NET Web Forms: 

 

In our EJ1 PDF Viewer, we can initially set the filename for the pdf document using fileName property. The document will be downloaded with the filename which we declared in the filename property. We have shared the sample and code snippet for your reference. 

 

Code snippet: 

 

 

var pdfviewerObj = $("#ContentPlaceHolder1_PdfViewer1").data("ejPdfViewer"); 

pdfviewerObj.fileName = "pdf-document.pdf"; 

 

 

 

Sample: 

https://www.syncfusion.com/downloads/support/directtrac/general/ze/PdfViewerWeb_(5)9866144798356310 

 

For Blazor: 

 

If you want to use in blazor PDF Viewer, we can set the filename for downloaded document by using downloadFileName property. If we load the document as base 64 string, we must provide the document name using the property downloadFileName. And we have shared the code snippet and sample for your reference. 

 

Code snippet: 

 

 

<SfPdfViewerServer @ref="@PdfViewer" DocumentPath="@DocumentPath" DownloadFileName="@DownloadFileName"/> 

public string DownloadFileName { get; set; } = "Syncfusion.pdf"; /> 

 

 

 

 

Sample:

Kindly try it and revert us, if you have any concerns about this.

Thanks for your response, but this wont work for me. I attached again my example.

• I set the filename when initializing the pdfviewerObj
  var pdfviewerObj = $("#PdfViewer1").data("ejPdfViewer");
  pdfviewerObj.filename = "dummyName4711.pdf";
• I also tried to set the filename when downloading the file or when i load the document
  <ej:PdfViewer id="PdfViewer1" runat="server" style="width: 100%" PdfService="Local" DownloadStart="docLoad" DocumentLoaded="docLoad"></ej:PdfViewer>
  function docLoad()
  {   var pdfviewerObjDownload = $("#PdfViewer1").data("ejPdfViewer");
       pdfviewerObjDownload.filename = "dummyName4713.pdf";
  }

But none of these ways works for me.
Can you give me a hint what is the problem?? 

Could be the reason, that I read the document as a bytearray and set the document path to it? (PdfViewer1.DocumentPath = data:application/pdf;base64,byteArray)

Regards 

Matthias

Hi Matthias, 

 

We have checked the sample which you have shared. In this, you have provided the filename for the document as “filename” instead of the property “fileName”. So, that the document is downloaded as undefined.pdf. We have modified the sample for your reference. 

 

Sample:  https://www.syncfusion.com/downloads/support/directtrac/general/ze/Download_setFilename223779354  

 

Kindly try this and revert us, if you have any concerns about this.
