hi,
i have to download a pdf file on a link button click from a content page.
i am using following code :

MIDL

Response.ContentType = "Application/pdf";
        Response.AppendHeader("Content-Disposition", "attachment; filename=Softgen.pdf");
        Response.TransmitFile(Server.MapPath("Hosts_Win_Brochure.pdf"));
        Response.End();

but it is giving error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.<br />
Details: Error parsing near '%PDF-1.5<br />
%��<br />

Hi Naveen,

you can do using following function with passing file path

VB

Public Shared Function DownloadFile(ByVal filePath As String) As Boolean
        Try
            If File.Exists(HttpContext.Current.Server.MapPath(filePath)) Then
                Dim strFileName As String = ""
                strFileName = System.IO.Path.GetFileName(HttpContext.Current.Server.MapPath(filePath))
                strFileName = strFileName.Replace(" ", "%20")
                HttpContext.Current.Response.ContentType = "application/octet-stream"
                HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" & strFileName) ' System.IO.Path.GetFileName(HttpContext.Current.Server.MapPath(filePath)))
                HttpContext.Current.Response.Clear()
                HttpContext.Current.Response.WriteFile(HttpContext.Current.Server.MapPath(filePath))
                HttpContext.Current.Response.End()
            Else
                Return False
            End If
        Catch ex As Exception
            Return False
        End Try
    End Function

Please do let me know, if you have any doubt.
