MVC pagedlist日期在第二页上失去价值 [英] mvc pagedlist date loses value on second page

问题描述

我有一个索引页面，上面有各种过滤选项，所有这些选项都包含在PagedList中.除日期外，它们似乎都工作正常.

I have an Index page with various filtering options on it, all included within a PagedList. They all appear to be working fine, except for the dates.

当我第一次按日期过滤时，它们可以正常工作，但是当我单击底部的页码时，用于日期的搜索条件就消失了.

When I first filter by date, they work fine however when I click on a page number at the bottom, the search criteria for my date is disappearing.

我看到我可以在页面列表中传递搜索词，并且可以看到此日期命中了控制器，并且发生了过滤，但是ViewBag.filterStartDate和ViewBag.filterEndDate并没有绑定到我的文本框中出于某些原因.

I can see that I can passing the search term in the paged list, and I can see this date hit my controller and the filtering happen but the ViewBag.filterStartDate and ViewBag.filterEndDate just aren't binding back to my textboxes for some reason.

推荐答案

@ Html.TextBox()可以将值拉出ModelState或ViewData.

@Html.TextBox() can pull values out of the ModelState or ViewData.

尝试像这样手动为输入的日期构建html:

Try building the html for the date input manually like this:

<input type="date" name="filterStartDate" id="filterStartDate" class="form-control date" value="@ViewBag.filterStartDate.ToString("yyyy-MM-dd")"/>
