my code is here

private List<AcoTransaction> AcoTrans
   {
       get
       {
           if (ViewState["AcoTransaction"] == null)
           {
               ViewState["AcoTransaction"] = new List<AcoTransaction>();
           }
           return (List<AcoTransaction>)ViewState["AcoTransaction"];
       }
       set
       { ViewState["AcoTransaction"] = value; }
   }

                           AddData.CreatedBy = ucTO.UserId;
                           AddData.CreatedOn = System.DateTime.Now;

                       }
                   }
                   else

                       txtDepositedAmount.Focus();
                   }
               }
           }

   }

推荐答案

public class AcoTransaction 
{
...
