    There is a pdf attachment in the gridview.I can open all other attachment except one(5).Each atachment is in each row of gridview.5th one, when i open below error message is coming

    There was an error opening this document.The file is damaged and could not be repaired. How to solve this issue.

    (When I open that PDF from its path(c:..)it is opening.)

    Code as below:

                     If UCase(Right(sFileName, 4)) = ".PDF" Then

    'set the http content type to "application/pdf"

    HttpContext.Current.Response.ContentType = "application/pdf"


    'set the http content type to "APPLICATION/OCTET-STREAM

    HttpContext.Current.Response.ContentType = "APPLICATION/OCTET-STREAM"

    End If '

    'initialize the http content-disposition header to

    ' indicate a file attachment with the filename

    Dim disHeader As String = "Attachment; Filename=" & sFileName

    HttpContext.Current.Response.AppendHeader("Content-Disposition", disHeader)

    ' transfer the file byte-by-byte to the response object
