Question

通过单击行上的删除按钮从以下代码中删除列表项ex：4中的第2项后，它在视图中显示1,2,3而不是1,3,4。当我调试视图时它显示正确的值，但是在页面呈现TextBoxFor AeroDromeID显示错误。删除机场按钮也显示正确的值。有人可以帮我解决这个问题。

控制器

    [HttpPost]
    [MultipleButton(Name = "action", Argument = "DeleteAerodrome")]
    public ActionResult DeleteAerodrome(FormCollection fc)
    {
        int AerodromeID = Int32.Parse(fc["action:DeleteAerodrome"]);
        var studentSignoutModel = new StudentSignoutViewModel();
        UpdateModel<StudentSignoutViewModel>(studentSignoutModel);
        if (studentSignoutModel.Aerodromes.Count > 0)
            studentSignoutModel.Aerodromes.RemoveAll(m => m.AerodromeID == AerodromeID);
        return View("StudentSignoutStageView", studentSignoutModel);
    }

查看

@if (Model.Aerodromes != null && Model.Aerodromes.Any())
                        {
                            for (int i = 0; i < Model.Aerodromes.Count; i++)
                            {
                                <tr>
                                    <td>@Html.TextBoxFor(a => Model.Aerodromes[i].AerodromeID, new { @class = "form-control"})</td>
                                    <td>@Html.TextBoxFor(a => Model.Aerodromes[i].CloudBase, new { @class = "form-control" })</td>

                                    <td>@Html.TextBoxFor(a => Model.Aerodromes[i].Visibility, new { @class = "form-control" })</td>

                                    <td>@Html.TextBoxFor(a => Model.Aerodromes[i].Wind, new { @class = "form-control" })</td>

                                    <td>@Html.TextBoxFor(a => Model.Aerodromes[i].Crosswind, new { @class = "form-control" })</td>

                                    <td>@Html.TextBoxFor(a => Model.Aerodromes[i].InterTempo, new { @class = "form-control" })</td>
                                    <td>
                                    <input type="submit" id="BtnDelAerodrome" value="@Model.Aerodromes[i].AerodromeID" name="action:DeleteAerodrome" style="font-size:1em" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete the record with AerodromeID = '+ @Model.Aerodromes[i].AerodromeID);" />
                                    </td>
                                </tr>
                            }
                        }

我认为当我们使用TextBoxFor时，从服务器端渲染时应该存在数据绑定概念的错误。当我使用模型绑定器的html标签输入时，它工作。这很容易复制。

在MVC中删除了不正确的项目
