Stored procedure executing but not able to access data in asp.net

Question

I have a stored procedure that executes perfectly in SQL Server. However I am not able to access the rows that are return by it in asp.net from Data Access Layer

My DataAccessLayer code is as follows:

 public List<AdvancePaymentRep> getPaymentAdvanceData(int? InternalCompany = 0, string Currency = "", DateTime? InvoiceDateFrom = null, DateTime? InvoiceDateTo = null, DateTime? AdvDateDueFrom = null, DateTime? AdvDateDueTo = null)
    {
      CreateConnectionString();
      List<AdvancePaymentRep> paymentAdvanceCollection = new List<AdvancePaymentRep>();
      SqlDataReader rdrval = null;
      SqlCommand command1 = sqlConnection.CreateCommand();
      command1.CommandType = System.Data.CommandType.StoredProcedure;
      command1.CommandText = "[dbo].[NST_GetDataForAdvancePaymentReport]";

      if (InternalCompany != 0)
      {

        SqlParameter parametersInternalCompany = new SqlParameter();
        parametersInternalCompany.ParameterName = "@AlhInternalCie";
        parametersInternalCompany.SqlDbType = System.Data.SqlDbType.Int;
        parametersInternalCompany.Direction = ParameterDirection.Input;
        parametersInternalCompany.Value = InternalCompany;
        command1.Parameters.Add(parametersInternalCompany);
      }

      SqlParameter parametersCurrency = new SqlParameter();
      parametersCurrency.ParameterName = "@AlhCurrency";
      parametersCurrency.SqlDbType = System.Data.SqlDbType.NVarChar;
      parametersCurrency.Direction = ParameterDirection.Input;
      parametersCurrency.Value = Currency;
      command1.Parameters.Add(parametersCurrency);

      if (InvoiceDateFrom != Convert.ToDateTime("01/01/0001 00:00:00"))
      {

        SqlParameter parametersInvoiceDateFrom = new SqlParameter();
        parametersInvoiceDateFrom.ParameterName = "@AldDtCreatedFrom";
        parametersInvoiceDateFrom.SqlDbType = System.Data.SqlDbType.Date;
        parametersInvoiceDateFrom.Direction = ParameterDirection.Input;
        parametersInvoiceDateFrom.Value = InvoiceDateFrom;
        command1.Parameters.Add(parametersInvoiceDateFrom);
      }

      if (InvoiceDateTo != Convert.ToDateTime("01/01/0001 00:00:00"))
      {
        SqlParameter parametersInvoiceDateTo = new SqlParameter();
        parametersInvoiceDateTo.ParameterName = "@AldDtCreatedTo";
        parametersInvoiceDateTo.SqlDbType = System.Data.SqlDbType.Date;
        parametersInvoiceDateTo.Direction = ParameterDirection.Input;
        parametersInvoiceDateTo.Value = InvoiceDateTo;
        command1.Parameters.Add(parametersInvoiceDateTo);

      }

      if (AdvDateDueFrom != Convert.ToDateTime("01/01/0001 00:00:00"))
      {
        SqlParameter parametersInvoiceDateDueFrom = new SqlParameter();
        parametersInvoiceDateDueFrom.ParameterName = "@InvhDtDueFrom";
        parametersInvoiceDateDueFrom.SqlDbType = System.Data.SqlDbType.Date;
        parametersInvoiceDateDueFrom.Direction = ParameterDirection.Input;
        parametersInvoiceDateDueFrom.Value = AdvDateDueFrom;
        command1.Parameters.Add(parametersInvoiceDateDueFrom);
      }


      if (AdvDateDueTo != Convert.ToDateTime("01/01/0001 00:00:00"))
      {
        SqlParameter parametersInvoiceDateDueTo = new SqlParameter();
        parametersInvoiceDateDueTo.ParameterName = "@InvhDtDueTo";
        parametersInvoiceDateDueTo.SqlDbType = System.Data.SqlDbType.Date;
        parametersInvoiceDateDueTo.Direction = ParameterDirection.Input;
        parametersInvoiceDateDueTo.Value = AdvDateDueTo;
        command1.Parameters.Add(parametersInvoiceDateDueTo);
      }

      try
      {
        if (sqlConnection == null)
        {
          sqlConnection.Open();
        }
        rdrval = command1.ExecuteReader(); // Getting HasRows = false out here 

EDIT : Have solved the issue there was some problem with how i had supplied the

Answer 1

The last command in your SP should be a SELECT command. Else, you get other results such as the number of rows affected and such. Management Studio is still able to display rows created from one of the SELECTs in your SP but actually they are not the first "thing" that is returned when you call an ADO.NET command against that SP.
