                   SqlCommand cmd = new SqlCommand();
                   cmd.CommandText = "INSERT_RETAILER";
                   cmd.CommandType = System.Data.CommandType.StoredProcedure;
                   cmd.Connection = conn;
                   SqlParameter[] sqlParams=new SqlParameter [8];

                   SqlParameter RetailerCode = new SqlParameter("@RetailerCode", objRetailer.RetailerCode);

                   EVD_No.DbType = System.Data.DbType.String;
                   sqlParams[2] = EVD_No;

                   SqlParameter Address = new SqlParameter("@Address", objRetailer.Address);

                   WorkingHours.DbType = System.Data.DbType.Double;
                   sqlParams[5] = WorkingHours;

                   SqlParameter ContactPerson_Name = new SqlParameter("@ContactPerson_Name", objRetailer.ContactPerson_Name);
                   ContactPerson_Name.Direction = System.Data.ParameterDirection.Input;
                   ContactPerson_Name.DbType = System.Data.DbType.String;
                   sqlParams[6] = ContactPerson_Name;

                   SqlParameter ContactPerson_Phone = new SqlParameter("@ContactPerson_Phone", objRetailer.ContactPerson_Phone);
                   ContactPerson_Phone.Direction = System.Data.ParameterDirection.Input;

Which line throws the Exception?

Is there a possibility that you are using the sqlParams more than 1 for multiple commands?

what's the exception message?

For the given below line you are missing the "@" symbol. Don't know if this is the exact reason, but Microsoft sometime throws strange error messages for simple errors!!!! :)

SqlParameter EVD_No = new SqlParameter("EVD_No", objRetailer.EVD_No);

Try to get rid of your array and add your SqlParameters one by one ; this will, for sure, be much more debuggable.
Unless there's some code you do not show, the use of the array does not provide any added value here ; it just makes the debugging harder.
