我有一个索引页，其上有各种过滤选项，全部包含在PagedList中。除了日期之外，它们似乎都工作正常。mvc pagedlist日期在第二页丢失值
当我第一次过滤日期时，他们工作正常，但是当我点击底部的页码时，我的日期的搜索条件正在消失。
我可以看到，我可以通过搜索项在分页列表中，我可以看到这个日期击中了我的控制和过滤发生，但ViewBag.filterStartDate和ViewBag.filterEndDate只是没有约束力回到我的文本框因为某些原因。

作业从索引操作返回时是否正确排序？ – derape 2015-03-31 08:45:21
我现在实际上没有使用任何排序。 sortOrder当前未被使用。相反，我只是通过DateCreated DESC对它们全部进行排序，但是我选择忽略那一行代码，因为我认为它对于我遇到的问题并不重要。 – 2015-03-31 09:04:27
