{
RoomTypeID = roomType.RoomTypeID,
facilitiesInRoom = LoadFacilityInRoom()
});
}
return showEditRoomViewModel;
}
can someone tell me, where is my mistake??

Answer 1

When you are inserting RoomtypeId in Database, you are using ExecuteNonQuery() method, It will always return 1 whenever you insert a new record in it,
If you are using stored procedure for inserting,you can use
select Scope_identity()
after insertion.
