              dt.Columns.Add("ExHouse");// create column 2           
              dt.Columns.Add("RemName");
              dt.Columns.Add("Currency");
              dt.Columns.Add("Amount");
              dt.Columns.Add("LKRAmount");
              //dt.Columns.Add(new DataColumn("Comission", typeof(string))); 
              dt.Columns.Add("Comission");
              dt.Columns.Add("ValueDate");
  
              DataRow dr = dt.NewRow(); // Create new Row
              TextBox comi=new TextBox();
              dr["TransDate"] = RemittanceToSelectedTable.TransDate; 
              dr["ExHouse"] = RemittanceToSelectedTable.ExHouse; //add data to coolumn no2
              dr["RemName"] = RemittanceToSelectedTable.RemName;
              dr["Currency"] = RemittanceToSelectedTable.Currency;
              dr["Amount"] = RemittanceToSelectedTable.Amount;
              dr["LKRAmount"] = RemittanceToSelectedTable.LKRAmount;
  
              dr["ValueDate"] = RemittanceToSelectedTable.ValueDate;
              dr["Comission"] = comi;
  
              aa.Add((string)dr["TransDate"]); 
              ab.Add((string)dr["ExHouse"]);
              ac.Add((string)dr["RemName"]);
              ad.Add((string)dr["Currency"]);
              ae.Add((string)dr["Amount"]);
              af.Add((string)dr["LKRAmount"]);
            //  ah.Add((string)dr["Comission"]);
              ag.Add((string)dr["ValueDate"]); 
  
  
              for (i = 0; i &lt; ag.Count; i++)
              {
                  dt.Rows.Add(aa[i], ab[i], ac[i], ad[i], ae[i], af[i], ag[i]); // add rows to data table
              }
  
              return dt;
