string embed = "<object data=\"{0}\" type=\"application/pdf\" width=\"500px\" height=\"300px\">";
embed += "If you are unable to view file, you can download from here";
embed += " or download <a target = \"_blank\" href = \"http://get.adobe.com/reader/\">Adobe PDF Reader</a> to view the file.";
embed += "</object>";

return RedirectToAction("Index");
}

popup view:
#using (Html.BeginForm("DisplayPDF", "Scan", FormMethod.Post))
{
View PDF
}
on Scan controller:-
public ActionResult DisplayPDF()
{
byte[] byteArray = GetPdfFromDB(4);
MemoryStream pdfStream = new MemoryStream();
pdfStream.Write(byteArray, 0, byteArray.Length);
pdfStream.Position = 0;
return new FileStreamResult(pdfStream, "application/pdf");
}
private byte[] GetPdfFromDB(int id)
{
#region
byte[] bytes = { };
string constr = System.Configuration.ConfigurationManager.ConnectionStrings["Connection"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandText = "SELECT Scan_Pdf_File FROM PWF_InvoiceMain WHERE InvoiceID=#Id and Enabled = 1";
cmd.Parameters.AddWithValue("#Id", id);
cmd.Connection = con;
con.Open();
using (SqlDataReader sdr = cmd.ExecuteReader())
{
if (sdr.HasRows == true)
{
sdr.Read();
bytes = (byte[])sdr["Scan_Pdf_File"];
}
}
con.Close();
}
}
return bytes;
#endregion
