Question

我的一个同事创建了一个模型，现在就是。

模型

[Serializable]
public class ModifyCollegeListModel
{
    public List<SchoolModel> CollegeList { get; set; }
    public List<SchoolListModel> SchoolList { get; set; }
    public string Notes { get; set; }
    public int QuestionnaireId { get; set; }
}

[Serializable]
public class SchoolModel
{
    public Guid SchoolId { get; set; }
    public string SchoolName { get; set; }
    public string StateName { get; set; }
    public int DisplayIndex { get; set; }
    public int DetailId { get; set; }
    public int CategoryId { get; set; }
    public int? ApplicationStatusId { get; set; }
}

我打算创建一个循环来生成ApplicationStatusId的radiobutton列表，就像这样......

剃刀代码

   @foreach (SchoolModel justright in Model.CollegeList.Where(m => m.CategoryId == 3).OrderBy(m => m.SchoolName).ToList<SchoolModel>())
    {
        <tr class="@HtmlHelpers.WriteIf(eventCounter % 2 == 0, "even", "odd")">
                <td class="school"><b>@justright.SchoolName</b></td>
                <td class="location"><b>@justright.StateName</b></td>
            <td><label>@Html.RadioButtonFor(x => justright.SchoolId, (int)BrightHorizons.CC.BusinessLogic.CollegeListApplicationStatusEnum.DidNotApply)</label></td>
            <td><label>@Html.RadioButtonFor(x => justright.SchoolId, (int)BrightHorizons.CC.BusinessLogic.CollegeListApplicationStatusEnum.Accepted)</label></td>
            <td><label>@Html.RadioButtonFor(x => justright.SchoolId, (int)BrightHorizons.CC.BusinessLogic.CollegeListApplicationStatusEnum.NotAccepted)</label></td>
        </tr>

    }

但是，所发生的是所有创建的radiobhutton具有相同的名称，因此它们被分组为一个巨大的radiobutton集合。不是通过schoolID ... 划伤头

有人可以帮助我，并指出我如何能够创建按行分组的单选按钮的正确方向吗？

Answer 1

我会做两件事。

首先，我会从视图中删除过滤逻辑。我的意思是这部分：

Model.CollegeList.Where(m => m.CategoryId == 3).OrderBy(m => m.SchoolName).ToList<SchoolModel>()

这种逻辑属于服务。它也会使视图更清晰。

其次，我认为您需要使用for循环，因此MVC会根据您的需要将所有内容绑定：

for (int i = 0; i < Model.CollegeList.Count; i++) {
    <tr class="@HtmlHelpers.WriteIf(eventCounter % 2 == 0, "even", "odd")">
        <td class="school"><b>@CollegeList[i].SchoolName</b></td>
        <td class="location"><b>@CollegeList[i].StateName</b></td>
        <td><label>@Html.RadioButtonFor(x => x.CollegeList[i].SchoolId, (int)BrightHorizons.CC.BusinessLogic.CollegeListApplicationStatusEnum.DidNotApply)</label></td>
        <td><label>@Html.RadioButtonFor(x => x.CollegeList[i].SchoolId, (int)BrightHorizons.CC.BusinessLogic.CollegeListApplicationStatusEnum.Accepted)</label></td>
        <td><label>@Html.RadioButtonFor(x => x.CollegeList[i].SchoolId, (int)BrightHorizons.CC.BusinessLogic.CollegeListApplicationStatusEnum.NotAccepted)</label></td>
    </tr>
}

使用for循环后你会注意到，radiobutton名称和ID也包含在CollegeList中的索引。例如：

<input id="CollegeList_0__SchoolId" name="CollegeList[0].SchoolId" type="radio" value="2">
