change the navigateURL to what I have . . . eg: remove the reviewDocuments.Aspx part from your HL link.

can you confirm that

c:\cbha\docs\system login.docx exists?

Remove the server.map path.

Does reviewDocument.aspx exist? If you put a path like "C:\..." it will try to open the file on the client computer not the server. You can add code the reviewDocument.aspx so that it reads the file and sends it to client.

thank you very much for the guide.

I created a dynamic button and used the code below and it is working

  Protected Sub btn_click(ByVal sender As Object, ByVal e As EventArgs)
        Dim a = CType(sender, Button).ID
        Dim filename As String = Mid(a, a.IndexOf("_") + 2, a.Length)
        Dim ext As String = IO.Path.GetExtension(Server.MapPath("docs\" + filename))
        Dim fname As String = Server.MapPath("docs\" + filename)
        Response.ContentType = ReturnExtension(ext)
        Response.AppendHeader("Content-Disposition", "attachment; filename=" & filename)
        Response.TransmitFile(fname)
        Response.End()
    End Sub

It is not a very direct solution to the problem but it is an alternative that works
