pdf file not loading from website

Question

How do I open a pdf file that has been saved on the server on the client side. I was creating a process to do this but it has not worked (System.Diagnostics.Process.Start(pdfFilePath + pdffileName);). I need to open this file on the client side as they need to send it the label print.

Post any error messages, also what do you mean by "has not worked" — Harry, Mar 31 '15 at 14:48
there where no error messages as nothing was happening. I had been using the process.start to open the pdf file locally while I was still developing when I published my site I tried to load the pdf file from the site and now nothing is happening. I am not to sure what I could do to fix this. — Sheena Weber, Mar 31 '15 at 14:57

try to write the file into the response. You try to open it on the server.

Context.Response.Buffer = false;
        FileStream inStr = null;
        byte[] buffer = new byte[1024];
        long byteCount; inStr = File.OpenRead(pdfFilePath + pdffileName);
        while ((byteCount = inStr.Read(buffer, 0, buffer.Length)) > 0) {
            if (Context.Response.IsClientConnected) {
                Context.Response.ContentType = "application/pdf";
                Context.Response.OutputStream.Write(buffer, 0, buffer.Length);
                Context.Response.Flush();
            }
        }

You either need to stream the file to the client (as the answer above indicates), or save it to a location under the site and give the user a link to it. You shouldn't need to start a process - link to the file and the browser will figure out what application to use to open it.

(You MAY need to set up a MIME type in IIS)

For example, assuming you save in the site under PDFFiles:

HyperLink pdfLink = new Hyperlink();
pdfLink.NavigateUrl = "~/PDFFiles/" + filename

Then add the link to your page controls. (Or you can hard-code the link in the ASPX file and set the NavigateUrl attribute in codebehind - however you want to do it)
