I have documents saved in a SQL Server database as varbinary(MAX).



I am trying to retrieve the document from the database with below code. The problem I am facing is that no matter the browser I use, I don't get any response back. No dialog the browser just displays the turning circle.
Any suggestions would be highly appreciated..



if (e.ButtonID != "Download") 
return;

int id = 2;
byte[] bytes;
string fileName, contentType;

string constr = ConfigurationManager.ConnectionStrings["bexsConnectionString"].ConnectionString;

using (SqlConnection con = new SqlConnection(constr))

using (SqlCommand cmd = new SqlCommand())

cmd.CommandText = "select Title, WillData, MIMEType from Will_documents where Doc_id = @Id";
cmd.Parameters.AddWithValue("@Id", id);
cmd.Connection = con;

con.Open();

using (SqlDataReader sdr = cmd.ExecuteReader())

sdr.Read();
bytes = (byte[])sdr["WillData"];
contentType = sdr["MIMEType"].ToString();
fileName = sdr["Title"].ToString();

Response.Buffer = true;
Response.Charset = "";
Response.Clear();
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = contentType;
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();


con.Close();

  • I assume you stepped through the code to ensure that you are really getting a result back from the DB?
