我想要在SelectDaycshtml
页面呈现查看页面ViewByDay.cshtml
的员工详细信息。概念是从下拉列表中选择一周中的几天,并在ViewByDay
中检索与当天相关的信息。为了做到这一点,我在SelectDay
中使用了@Html.RenderAction("ViewByDay")
。但是我得到这个错误如何在C#MVC5中查看动作?
过程或函数'ViewByDay'期望参数'@Days',它没有提供。
这是我的视图类的代码段和控制器:
SelectDay.cshtml
@model CrudMvc.Models.EmpInfoModels
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Select Employee By Days</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.Days, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.DropDownListFor(model => model.Days, (List <SelectListItem>)ViewBag.DayItems, new { @class = "form-control" })
@Html.ValidationMessageFor(model => model.Days, "", new { @class = "text-danger" })
</div>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Select" class="btn btn-default" />
</div>
</div>
}
<div>
@{ Html.RenderAction("ViewByDay"); }
// @{ Html.RenderPartial("_ViewByDay");}
// @Html.Partial("_ViewByDay")
// @Html.ActionLink("Get All Employee Details", "GetAllEmpDetails","Employee") *@
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
ViewByDay.cshtml
@model IList<CrudMvc.Models.EmpInfoModels>
<div>
<h4>ListEmpByDays</h4>
<hr />
<table class="table">
<tr>
<th>Employee Name</th>
<th>Day</th>
<th>Destination</th>
</tr>
@foreach (var item in Model)
{
<tr>
<td>@Html.DisplayFor(modelItem => item.EmpName)</td>
<td>@Html.DisplayFor(modelItem => item.Days)</td>
<td>@Html.DisplayFor(modelItem => item.Destination)</td>
</tr>
}
</table>
</div>
<p>@Html.ActionLink("Back to List", "GetAllEmpDetails")</p>
控制器硒lectDay和ViewByDay
public ActionResult SelectDay()
{
var days= new List<SelectListItem>();
days.Add(new SelectListItem { Text = "Monday", Value = "Monday" });
days.Add(new SelectListItem { Text = "Tuesday", Value = "Tuesday" });
days.Add(new SelectListItem { Text = "Wednesday", Value = "Wednesday" });
days.Add(new SelectListItem { Text = "Thursday", Value = "Thursday" });
days.Add(new SelectListItem { Text = "Friday", Value = "Friday" });
ViewBag.DayItems = days;
return View();
}
[HttpPost]
public ActionResult SelectDay(string Days)
{
return RedirectToAction("ViewByDay", new {Days = Days});
}
public ActionResult ViewByDay(string days)
{
EmpRepository EmpRepo = new EmpRepository();
ModelState.Clear();
var emps = EmpRepo.ViewByDay(days);
return View(emps);
}
删除'@ {Html.RenderAction( “ViewByDay”); }'from'SelectDay.cshtml' - 你有一个表单,并发布'Days'的值,然后重定向到'ViewByDay'方法/视图。注意:'ViewByDay()'方法中'ModelState.Clear();'是毫无意义的(ModelState中没有任何东西可以清除) –
您的代码没有意义,如果要在第一个view,然后你需要一个带有FormMethod.Get的窗体,'SelectDay()'方法需要'Days'的一个参数(并且你需要返回模型),但是使用ajax会得到更好的性能根据选定的选项更新DOM –
亲爱的朋友,我建议你阅读部分视图,然后在ViewByDay和SelectDay中使用相同的局部视图,否则我认为Stefan Kert答案是正确的。 –
