Question

我的asp.net视图中存在问题。我有一个foreach循环，我不能把我的第一次迭代放到我的表格中。

这就是代码：

<div id="@item.Name" class="tab-pane fade in active">
    <div class="row">
        @{int i = 0;}
        @foreach (var prod in item.Products.Where(p => p.Type_Id == item.Id && p.IsDeleted != true))
        {
            using (Html.BeginForm("AddOrderRow", "Orders", new { enctype = "multipart/form-data", @class = "form-inline" }))
            {
                <input type="hidden" value="@ViewBag.orderId" name="Order_Id" />
                <input type="hidden" value="@prod.Id" name="ProductID" />
                <input type="hidden" value="@prod.Price" name="Price" />
                <div class="col-sm-3" style="padding-bottom:20px">
                    <div align="center">
                        <button style="background-color:transparent; border-color:transparent">
                            <img class="img-responsive" src='@VirtualPathUtility.ToAbsolute(String.Format("{0}/{1}", System.Configuration.ConfigurationManager.AppSettings["ProdUploadPath"], prod.Image))' style="max-height: 100px" data-toggle="tooltip" title="@prod.Name">
                        </button>
                    </div>
                </div>
                if (i % 4 == 3)
                {
                    @:</div><div class="row">
                }
                i++;
            }
        }
    </div>
</div>

这就是它的样子：

正如你所看到的，只有第一行的第一行才是我的形式。

我的建议如果你想要保存列表，请使用保存列表而不是迭代表单

示例控制器在这里;当我学习mvc hahaha时的那个

     public ActionResult Create(int? area, string now, string search, string message)
    {
        ViewBag.Area = new SelectList(CoreList.GetDropdown("UnitArea"), "DropdownId", "Value", area);
        ViewBag.SelectedArea = area;

        var newdate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);
        IFormatProvider culture = new CultureInfo(CultureInfo.CurrentCulture.Name, true);

        if (!string.IsNullOrWhiteSpace(now))
        {
            DateTime.TryParse(now, culture, DateTimeStyles.AssumeLocal, out newdate);
        }

        ViewBag.dateFilter = newdate.ToString(CultureInfo
            .GetCultureInfo(CultureInfo.CurrentCulture.Name)
            .DateTimeFormat.ShortDatePattern);

        ViewBag.Search = search;
        var attendances = (from p in db.MstUnitDriverPairings

                           join x in db.TrnAttendanceUnits
                           .Where(o => o.PresentDate.Value.Year == newdate.Year &&

            throw;
        }

        return RedirectToAction("Index","Transaction/Attendance", new {area, search, message, now = presentDate });
    }

这是模特

public class Attendance
{
    public int DriverId { get; set; }

    [Display(Name = "Name")]
    public string DriverName { get; set; }

    [Display(Name = "Driver In")]
    public bool DriverIn { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? DriverInDate { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? DriverOutDateBefore { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? DriverInDateBefore { get; set; }

    [Display(Name = "Driver Out")]
    public bool DriverOut { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? DriverOutDate { get; set; }
    public int UnitId { get; set; }

    [Display(Name = "Police Number")]
    public string PoliceNumber { get; set; }

    [Display(Name = "Unit In")]
    public bool UnitIn { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? UnitInDate { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? UnitOutDateBefore { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? UnitInDateBefore { get; set; }

    [Display(Name = "Unit Out")]
    public bool UnitOut { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime? UnitOutDate { get; set; }
}
