ASP.NET MVC 编辑单个列的所有行答案

【问题标题】：ASP.NET MVC Edit All rows for a single ColumnASP.NET MVC 编辑单个列的所有行
【发布时间】：2019-02-20 01:16:46
【问题描述】：

我有一张表Employees 有一堆列。我正在寻找一种方法来编辑其中一个列，以便它影响所有行。

该列名为accrualmonth，用于sql server 中的计算列。

。

理想情况下，我想提交一个包含 1 到 12 数字下拉列表的表单。

我已经创建了一个 CRUD 操作，因此我可以为各个行编辑它，但理想情况下我需要“批量”进行操作

 public ActionResult Edit(int? id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Employee employee = db.Employees.Find(id);
        if (employee == null)
        {
            return HttpNotFound();
        }
        ViewBag.AreaID = new SelectList(db.Areas, "AreaID", "Area1", employee.AreaID);
        ViewBag.DisciplineID = new SelectList(db.Disciplines, "DisciplineID", "Discipline1", employee.DisciplineID);
        ViewBag.HeadQuatersID = new SelectList(db.HeadQuaters, "HeadQuatersID", "Name", employee.HeadQuatersID);
        ViewBag.ShiftID = new SelectList(db.Shifts, "ShiftID", "Shift1", employee.ShiftID);
        ViewBag.SiteID = new SelectList(db.Sites, "SiteID", "SiteName", employee.SiteID);
        return View(employee);
    }

    // POST: Accruals/Edit/5
    // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
    // more details see http://go.microsoft.com/fwlink/?LinkId=317598.
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit([Bind(Include = "EmployeeID,FullName,Email,StartDate,ShiftID,AreaID,DisciplineID,SiteID,ALCategory,HoursTaken,HoursCarriedForward,Comments,SickLeaveTaken,SickLeaveEntitlementRemaining,StudyLeaveEntitlement,StudyLeaveTaken,StudyLeaveRemaining,ExamLeaveTaken,ForceMajeure,BereavementLeaveTaken,MaternityLeaveTaken,ParentalLeaveTaken,AdoptionLeaveTaken,ManagerEmail,AreaManagerEmail,SickLeaveEntitlement,ActiveStatus,HeadQuatersID,Apprentice,AwardedLeave,TotalHoursThisYear,EntitlementRemainingThisYear,LeaveDate,LeavingDatEntitlement,accrualmonth,AllowanceToEndofMonth,TotalHolsToAccru")] Employee employee)
    {
        if (ModelState.IsValid)
        {
            db.Entry(employee).State = EntityState.Modified;
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        ViewBag.AreaID = new SelectList(db.Areas, "AreaID", "Area1", employee.AreaID);
        ViewBag.DisciplineID = new SelectList(db.Disciplines, "DisciplineID", "Discipline1", employee.DisciplineID);
        ViewBag.HeadQuatersID = new SelectList(db.HeadQuaters, "HeadQuatersID", "Name", employee.HeadQuatersID);
        ViewBag.ShiftID = new SelectList(db.Shifts, "ShiftID", "Shift1", employee.ShiftID);
        ViewBag.SiteID = new SelectList(db.Sites, "SiteID", "SiteName", employee.SiteID);
        return View(employee);
    }

我该如何着手解决这个问题？我会尝试在编辑视图上使用 foreach 以便它可以循环浏览所有条目。

查看：

【问题讨论】：

您可以截屏以获取更多详细信息吗？
@HienNguyen 完成！我真的只是在寻找一种方法来用某个值填充所有列我不确定如何实现这一点！
您想在表格或网格中编辑类似网格的多行，并且您想保存或更新一次吗？
@MianAlmas 我想基本上一次将每一行更改为 1 到 12 之间的某个值。我在取决于月份的计算中使用它，所以我需要更改所有条目以获得必填值！
@Conor8630 您需要更改所有行的一列值还是多个值？您需要安装一个名为 beginCollection 的 nuget 并查看此帖子 stackoverflow.com/questions/29774822/… github.com/danludwig/BeginCollectionItem

【解决方案1】：

在您的视图中使用以下内容进行强类型定义，是的，请确保将所有控件替换为“For”

{ 
         List<SelectListItem> listOfMonths = new List<SelectListItem>();
        listOfMonths.Add(new SelectListItem() { Text = "1", Value = "1" });
        listOfMonths.Add(new SelectListItem() { Text = "2", Value = "2" });
        listOfMonths.Add(new SelectListItem() { Text = "3", Value = "3" });
        listOfMonths.Add(new SelectListItem() { Text = "4", Value = "4" });
        listOfMonths.Add(new SelectListItem() { Text = "5", Value = "5" });
        listOfMonths.Add(new SelectListItem() { Text = "6", Value = "6" });
        listOfMonths.Add(new SelectListItem() { Text = "7", Value = "7" });
        listOfMonths.Add(new SelectListItem() { Text = "8", Value = "8" });
        listOfMonths.Add(new SelectListItem() { Text = "9", Value = "9" });
        listOfMonths.Add(new SelectListItem() { Text = "10", Value = "10" });
        listOfMonths.Add(new SelectListItem() { Text = "11", Value = "11" });
        listOfMonths.Add(new SelectListItem() { Text = "12", Value = "12" });
    }
    @Html.DropDownListFor(model => model.accrualmonth, listOfMonths, htmlAttributes: new { @class = "form-control" })
    @Html.ValidationMessageFor(model => model.accrualmonth, "", new { @class = "text-danger" })

如果你按照下面的操作，你会得到想要的结果。

使用任何名称创建一个 partialView 并添加这样的代码。

    @model HolidayTracker.Models.Employee
      List<SelectListItem> listOfMonths= (List<SelectListItem>)ViewData["listOfMonths"];

    @using (Html.BeginCollectionItem("employees"))
    {


     @Html.HiddenFor(model => model.EmployeeID)


@Html.HiddenFor(model => model.FullName)


@Html.HiddenFor(model => model.Email)


@Html.HiddenFor(model => model.StartDate)


@Html.HiddenFor(model => model.ShiftID)


@Html.HiddenFor(model => model.AreaID)


@Html.HiddenFor(model => model.DisciplineID)


@Html.HiddenFor(model => model.SiteID)


@Html.HiddenFor(model => model.ALCategory)


@Html.HiddenFor(model => model.HoursTaken)


@Html.HiddenFor(model => model.HoursCarriedForward)


@Html.HiddenFor(model => model.Comments)


@Html.HiddenFor(model => model.SickLeaveTaken)


@Html.HiddenFor(model => model.SickLeaveEntitlementRemaining)


@Html.HiddenFor(model => model.StudyLeaveTaken)


@Html.HiddenFor(model => model.StudyLeaveRemaining)


@Html.HiddenFor(model => model.ExamLeaveTaken)


@Html.HiddenFor(model => model.ForceMajeure)


@Html.HiddenFor(model => model.BereavementLeaveTaken)


@Html.HiddenFor(model => model.MaternityLeaveTaken)


@Html.HiddenFor(model => model.ParentalLeaveTaken)


@Html.HiddenFor(model => model.AdoptionLeaveTaken)


@Html.HiddenFor(model => model.ManagerEmail)


@Html.HiddenFor(model => model.AreaManagerEmail)


@Html.HiddenFor(model => model.SickLeaveEntitlement)


@Html.HiddenFor(model => model.ActiveStatus)


@Html.HiddenFor(model => model.HeadQuatersID)


@Html.HiddenFor(model => model.Apprentice)


@Html.HiddenFor(model => model.AwardedLeave)


@Html.HiddenFor(model => model.TotalHoursThisYear)


@Html.HiddenFor(model => model.EntitlementRemainingThisYear)


@Html.HiddenFor(model => model.LeaveDate)


@Html.HiddenFor(model => model.LeavingDatEntitlement)


@Html.HiddenFor(model => model.AllowanceToEndofMonth)


@Html.HiddenFor(model => model.TotalHolsToAccru)

<div class="form-group">
    @Html.LabelFor(model => model.accrualmonth, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.DropDownListFor(model => model.accrualmonth, listOfMonths, htmlAttributes: new { @class = "form-control" })
        @Html.ValidationMessageFor(model => model.accrualmonth, "", new { @class = "text-danger" })
    </div>
</div>
    }

然后使用上一页中添加此代码的部分视图，如果您说这是一个网格，则必须有多个行

在主视图中

List<SelectListItem> listOfMonths = new List<SelectListItem>();
                    listOfMonths.Add(new SelectListItem() { Text = "1", Value = "1" });
                    listOfMonths.Add(new SelectListItem() { Text = "2", Value = "2" });
                    listOfMonths.Add(new SelectListItem() { Text = "3", Value = "3" });
                    listOfMonths.Add(new SelectListItem() { Text = "4", Value = "4" });
                    listOfMonths.Add(new SelectListItem() { Text = "5", Value = "5" });
                    listOfMonths.Add(new SelectListItem() { Text = "6", Value = "6" });
                    listOfMonths.Add(new SelectListItem() { Text = "7", Value = "7" });
                    listOfMonths.Add(new SelectListItem() { Text = "8", Value = "8" });
                    listOfMonths.Add(new SelectListItem() { Text = "9", Value = "9" });
                    listOfMonths.Add(new SelectListItem() { Text = "10", Value = "10" });
                    listOfMonths.Add(new SelectListItem() { Text = "11", Value = "11" });
                    listOfMonths.Add(new SelectListItem() { Text = "12", Value = "12" });

foreach (var module in Model?.Related)
                                            {

@{Html.RenderPartial("_YourPartialViewName", module, new ViewDataDictionary() { { "ListOfMonths", listOfMonths } });}

                                            }

控制器会像这样接收。

 [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit(   List<Employee > employees)

如果术前名称相同，则无需包含绑定，您将通过此获得它
