Protected Sub DownloadFile(ByVal sender As Object, ByVal e As EventArgs)
Dim id As Integer = Integer.Parse(TryCast(sender, LinkButton).CommandArgument)
Dim fileName As String, contentType As String
Dim constr As String = ConfigurationManager.ConnectionStrings("RegistrationConnectionString").ConnectionString
Using con As New SqlConnection(constr)
Using cmd As New SqlCommand()
cmd.CommandText = "select * from upload where Id=@Id"
cmd.Parameters.AddWithValue("@Id", id)
cmd.Connection = con
con.Open()
Using sdr As SqlDataReader = cmd.ExecuteReader()
sdr.Read()
'bytes = DirectCast(sdr("ImagePath"), Byte())
'contentType = sdr("ContentType").ToString()
fileName = "D:\Documents\upload\" & sdr("ImagePath").ToString()
End Using
con.Close()
End Using
End Using
Response.Clear()
Response.Buffer = True
Response.Charset = ""
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.AppendHeader("Content-Disposition", Convert.ToString("attachment; filename=") & fileName)
