细节和编辑视图中的对齐问题

Question

我不太明白如何让它与 mvc 6 正确对齐。"dropdown" 有一个 CSS 标签，但它只是位置：相对并且不做任何事情全部。这都是使用 Entity Framework.

<div class="form-horizontal">
        <h4>Person</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        @Html.HiddenFor(model => model.PersonId)

        <div class="form-group">
            @Html.LabelFor(model => model.FullName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.DisplayFor(model => model.FullName, new { htmlAttributes = new { @class = "form-control" } })
            </div>
        </div>

        <div class="form-group">

                @Html.ValidationMessageFor(model => model.Roles, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">

                <input type="submit" value="Save" class="btn btn-default" />

UPDATE：这是我的 HTML 的更新，由下面的答案推荐。这使得页面上的每个元素都散落在各处。请参阅下一个屏幕截图。

@model NewUserTool.Models.PersonViewModel

@{
    ViewBag.Title = "Edit";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Edit</h2>

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Person</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        @Html.HiddenFor(model => model.PersonId)

        <div class="form-control-static">
            @Html.LabelFor(model => model.FullName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.DisplayFor(model => model.FullName, new { @class = "form-control" })
            </div>
        </div>

        <div class="form-control-static">
            @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.DisplayFor(model => model.Email, new { @class = "form-control" })
            </div>
        </div>

        <div class="form-control-static">
            @Html.LabelFor(model => model.Roles, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="dropdown">
                @Html.DropDownList("RoleList", null, new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.Roles, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-control-static">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Save" class="btn btn-default" />
            </div>
        </div>
    </div>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

是否这样做：

Answer 1

DisplayFor 不像 EditorFor 那样接受 htmlAttributes。对于 FullName 之类的字符串，默认显示只是转储字符串值而不包含任何 HTML，因此在大多数情况下，没有任何内容可以实际添加属性。但是，即使这确实有效，你仍然会在这里使用错误的 class，因为你正在寻找的实际上是 form-control-static 哪些样式文本要对齐，就好像它是输入 class form-control。所以你实际需要的代码是：

<p class="form-control-static">@Html.DisplayFor(m => m.Email)</p>

此外，您的下拉菜单未对齐，因为您没有正确传递 HTML 属性。匿名对象语法中的匿名对象用于 EditorFor。 EditorFor 中的该参数实际上用于附加视图数据。实际上，您正在向 ViewData 添加一个名为 htmlAttributes 的键，默认编辑器模板会在 ViewData 中查找此键并对其进行处理。但是，对于像 TextBoxFor、DropDownListFor 等助手，参数本身是针对 HTML 属性的。结果，您要告诉它添加一个名为 htmlAttributes 的属性并为其赋予该匿名对象的值，我什至不确定助手会用它做什么。长短不一，把代码改成：

@Html.DropDownList("RoleList", null, new { @class = "form-control" })

Answer 2

在您的 html 中，您从未正确包装 dropdown。如果您有一行，请务必声明列，总共 12。

<div class="form-group">
    <label class="control-label col-md-2" for="Roles">Roles</label>
    <div class="col-md-10">
        <div class="dropdown">
            <select class="form-control" id="RoleList" name="RoleList"><option selected="selected" value="71758b95-b2b1-410a-8267-ebbd26905102">Admin</option>
                <option value="5c0c5cba-fb44-4320-8d9c-e76544e77d60">Basic</option>
                <option value="c34e731d-30a2-42e5-9d64-d1c2bd33ef17">Create</option>
            </select>
            <span class="field-validation-valid text-danger" data-valmsg-for="Roles" data-valmsg-replace="true"></span>
        </div>
    </div>
</div>

此外，我确实将您的文本包装到 p 标签中，并应用了与标签相同的上边距。
