问题描述
我正在尝试通过相关实体对我的一个查询进行排序。 由于设计师不支持这一点，我的理解是我应该为我的查询挂钩PreprocessQuery事件并在那里添加order by子句。 所以我做了。
I'm trying to sort one of my queries by a related entity. Since the designer doesn't support this, my understanding is that I'm supposed to hook the PreprocessQuery event for my query and add an order by clause there. So I did.
partial void FilterStations_All_PreprocessQuery(ref IQueryable<FilterStation> query)
{
query = query.OrderBy(o => o.Broadcaster.CallLetters);
}
