ASP.net MVC - 集合的显示模板 [英] ASP.net MVC - Display Template for a collection

问题描述

我在 MVC 中有以下模型:

I have the following model in MVC:

public class ParentModel
{
    public string Property1 { get; set; }
    public string Property2 { get; set; }

    public IEnumerable<ChildModel> Children { get; set; }
}

当我想显示父模型的所有孩子时，我可以这样做:

When I want to display all of the children for the parent model I can do:

@Html.DisplayFor(m => m.Children)

然后我可以创建一个 ChildModel.cshtml 显示模板，DisplayFor 将自动遍历列表.

I can then create a ChildModel.cshtml display template and the DisplayFor will automatically iterate over the list.

如果我想为 IEnumerable 创建自定义模板怎么办?

What if I want to create a custom template for IEnumerable?

@model IEnumerable<ChildModel>

<table>
    <tr>
        <th>Property 1</th>
        <th>Property 2</th>
    </tr>
    ...
</table>

如何创建模型类型为 IEnumerable 的显示模板，然后调用 @Html.DisplayFor(m => m.Children)没有它抱怨模型类型错误?

How can I create a Display Template that has a model type of IEnumerable<ChildModel> and then call @Html.DisplayFor(m => m.Children) without it complaining about the model type being wrong?

推荐答案

像这样:

@Html.DisplayFor(m => m.Children, "YourTemplateName")

或者像这样:

[UIHint("YourTemplateName")]
public IEnumerable<ChildModel> Children { get; set; }

显然你会有~/Views/Shared/DisplayTemplates/YourTemplateName.cshtml:

@model IEnumerable<ChildModel>

<table>
    <tr>
        <th>Property 1</th>
        <th>Property 2</th>
    </tr>
    ...
</table>
