        string fileName = "TPR1" + DateTime.Now.Ticks + ".pdf";

        Document doc = new Document();
        DataTable dtBidTree = new DataTable();
       
        BidTreeBLL objBID = new BidTreeBLL();
        dtBidTree = objBID.GetBidTree(DID, DocType);
        try
        {
           if (dtBidTree.Rows.Count > 0)
           {
                        int btParentNodeID;
                        string btName = string.Empty;
                        string btType = string.Empty;
                        string btDetails = string.Empty;
                        bool btChagable = false;
                        string sbtDID1 = string.Empty;

               for (int m = 1; m < dtBidTree.Rows.Count; m++) // starting from 1 because, 0th row value not required
               {
                   string NodeValue = string.Empty;
                   NodeValue=dtBidTree.Rows[m]["btNodeID"].ToString();
                   NodeValue=dtBidTree.Rows[m]["btParentNodeID"].ToString();
                   NodeValue = dtBidTree.Rows[m]["btName"].ToString();
                   NodeValue = dtBidTree.Rows[m]["btType"].ToString();
                   NodeValue = dtBidTree.Rows[m]["btDetails"].ToString();
                   NodeValue=dtBidTree.Rows[m]["btChangable"].ToString();
                  
                   PdfWriter.GetInstance(doc, new FileStream(path + fileName, FileMode.Create));
                   doc.Open();
                   dtBidTree = objBID.GetBidTree(DID, DocType);
                   //doc.Add(new Paragraph("Hello World"));
//here doc.Add(NodeValue);but am getting error..so how can i bind to doc.add
//its generating only logo.
