Save Files to Database using Dynamic FileUpload controls in ASP.Net

Seems you did not refer my article completely. The very first link saves file and it shows how to do it by fetching Files form Request.Form

Using both my articles Uploading Multiple Files using JavaScript Dynamic FileUpload Controls in ASP.Net and Save Files to SQL Server Database using FileUpload Control

easily you can do the following

protected void btnUpload_Click(object sender, EventArgs e)
{
    for (int i = 0; i < Request.Files.Count; i++)
    {
        HttpPostedFile PostedFile = Request.Files[i];
        if (PostedFile.ContentLength > 0)
        {
            string FileName = System.IO.Path.GetFileName(PostedFile.FileName);      
            Stream fs = PostedFile.InputStream;

           BinaryReader br = new BinaryReader(fs);

           Byte[] bytes = br.ReadBytes((Int32)fs.Length);

         string strQuery = "insert into tblFiles(Name, ContentType, Data)" +

           " values (@Name, @ContentType, @Data)";

        SqlCommand cmd = new SqlCommand(strQuery);
        cmd.Parameters.Add("@Name", SqlDbType.VarChar).Value = filename;
        cmd.Parameters.Add("@ContentType", SqlDbType.VarChar).Value
          = PostedFile.ContentType;

        cmd.Parameters.Add("@Data", SqlDbType.Binary).Value = bytes;

        InsertUpdateData(cmd);
        }
    }
}
