How to download a pdf file in Composite c1

I'm trying to implement a functionality that enables a user to download a PDF on clicking on a hyper-link. What i've done is, I've created a global datatype Publications which takes values "Description" and "PDF DOC" and I've a user control with a hyper-link which binds the description as its text.

LinkButton1.Text = details.Description;
Composite.Data.DataReference<IMediaFile> i = new Composite.Data.DataReference<IMediaFile>((details as A.DataTypes.Publications).PdfDoc);
string filePath = "/media(" + i.Data.Id + ")";

and on the click on the link button I've...

Response.ContentType = "Application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=Test_PDF.pdf");
Response.TransmitFile(filePath );
Response.End();

this is showing an error saying "could not find file", any idea why?

Solution

  • solved it, just needed to give....string filePath = "~/media({" + i.Data.Id + "})"; instead of string filePath = "/media(" + i.Data.Id + ")";
