Dear All,

I am using following code to show .pdf file in new browser tab:

C#

string fileName = Regex.Replace(Proposal_No, @[/ ], "");
string filePath = Server.MapPath("~/Report_Pdf/Draft_Proposal/") + fileName + ".pdf";

WebClient client = new WebClient();
Byte[] buffer = client.DownloadData(filePath);

if (buffer != null)
{
    Response.ContentType = "application/pdf";
    Response.AddHeader("content-length", buffer.Length.ToString());
    Response.BinaryWrite(buffer);
}

But this code is not working and instead of downloading .pdf file, .aspx is downloading.

I have also tried following code:

C#

string fileName = Regex.Replace(Proposal_No, @[/ ], "");
string filePath = Server.MapPath("~/Report_Pdf/Draft_Proposal/") + fileName + ".pdf";

Response.ContentType = "application/pdf";
Response.TransmitFile(filePath);

But there is same problem as previous one.
Please help me to get rid of this problem.

Thank u all.

Did you try setting Content-Disposition: inline?

Try doing a Response.Clear before and end the response immediately after

C#

private void TestPdf()
    {
        string path = Server.MapPath("~\\C:\\rnd\\test.PDF");
        WebClient client = new WebClient();
        Byte[] buffer = client.DownloadData(path);
        if (buffer != null)
        {
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-length", buffer.Length.ToString());
            Response.BinaryWrite(buffer);
        }
    }

Its work for me.
When u mapping file make sure I n url / path its returning with .pdf ext.
