在 ASP.NET MVC 2 中模板化 Html.DisplayFor()

发布于 2024-08-20 12:31:37 字数 1529 浏览 6 评论 0原文

看起来,如果您仅使用 Html.DisplayFor(model => model) 而没有详细信息视图的模板,则生成的标记将如下所示:

<div class="display-label">first name</div>
<div class="display-field">Dan</div>
<div class="display-label">last name</div>
<div class="display-field">M</div>
<div class="display-label">email</div>
<div class="display-field">[email protected]</div>

这具有相当程度的灵活性。如果您为 display-labeldisplay-field 创建 CSS 类,您可以做很多事情,但是如果我想将其更改为这样的东西怎么办?

<p>
  <span class="display-label">first name</span>:
  <span class="display-field">Dan</span>
</p>
<p>
  <span class="display-label">last name</span>:
  <span class="display-field">M</span>
</p>
<p>
  <span class="display-label">email</span>:
  <span class="display-field">[email protected]</span>
</p>

请注意,现在属性-值对现在并排显示(而不是在单独的行上),并且每个属性后面都有一个冒号。

有没有办法创建一个自定义模板,当构建详细视图时,该模板将针对每个属性值对重复?

我不是在谈论模型的特定模板(例如,< code>Person 模板)或特定属性的模板(例如,EmailAddress 模板)。我想要一些可以让我描述属性值对外观的东西,然后 DispalyFor() 应该自动为我的模型或视图模型中的每个属性重复该模板。

It appears that if you just use Html.DisplayFor(model => model) with no templates for a Details view, the resulting markup will look something like this:

<div class="display-label">first name</div>
<div class="display-field">Dan</div>
<div class="display-label">last name</div>
<div class="display-field">M</div>
<div class="display-label">email</div>
<div class="display-field">[email protected]</div>

This has a fair degree of flexibility. If you create CSS classes for display-label and display-field, you can do quite a bit, but what if I wanted to change it to something like this?

<p>
  <span class="display-label">first name</span>:
  <span class="display-field">Dan</span>
</p>
<p>
  <span class="display-label">last name</span>:
  <span class="display-field">M</span>
</p>
<p>
  <span class="display-label">email</span>:
  <span class="display-field">[email protected]</span>
</p>

Note that now the attribute-value pairs now appear side-by-side (instead of on separate lines) and there is a colon after each attribute.

Is there any way to create a custom template that will be repeated for each attribute-value pair when a details view is scaffolded?

I'm not talking about a specific template for a model (e.g., a Person template) or a template for a particular property (e.g., an EmailAddress template). I want something that just lets me describe how an attribute-value pair looks, then DispalyFor() should automatically repeat that template for each property in my model or view model.

如何覆盖Object模板,例如

    <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
    <% if (ViewData.TemplateInfo.TemplateDepth > 3) { %>
        <%= ViewData.ModelMetadata.SimpleDisplayText %>
    <% } else { %>
        <table>
        <% foreach (ModelMetadata prop in ViewData.ModelMetadata.Properties.Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm))) { %>
            <% if (prop.HideSurroundingHtml) { %>
                <%= Html.Display(prop.PropertyName) %>
            <% } else { %>
                <tr>
                    <td>
                        <div class="display-label" style="text-align: right;">
                            <%= Html.Label(prop.PropertyName) %>
                        </div>
                    </td>
                    <td>
                        <div class="display-field">
                            <%= Html.Display(prop.PropertyName) %>
                            <%= Html.ValidationMessage(prop.PropertyName, "*") %>
                        </div>
                    </td>
                </tr>
            <% } %>
        <% } %>
        </table>
    <% } %>

How about overriding the Object template, e.g.

    <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
    <% if (ViewData.TemplateInfo.TemplateDepth > 3) { %>
        <%= ViewData.ModelMetadata.SimpleDisplayText %>
    <% } else { %>
        <table>
        <% foreach (ModelMetadata prop in ViewData.ModelMetadata.Properties.Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm))) { %>
            <% if (prop.HideSurroundingHtml) { %>
                <%= Html.Display(prop.PropertyName) %>
            <% } else { %>
                <tr>
                    <td>
                        <div class="display-label" style="text-align: right;">
                            <%= Html.Label(prop.PropertyName) %>
                        </div>
                    </td>
                    <td>
                        <div class="display-field">
                            <%= Html.Display(prop.PropertyName) %>
                            <%= Html.ValidationMessage(prop.PropertyName, "*") %>
                        </div>
                    </td>
                </tr>
            <% } %>
        <% } %>
        </table>
    <% } %>
