如何使用在的WebGrid列标题显示名称数据注解？ [英] How can I use DisplayName data annotations for column headers in WebGrid?

问题描述

我有我想要在使用的WebGrid助手的MVC 3视图显示汽车类。下面是汽车和它的元数据类。

I have a Car class that I'm trying to display in an MVC 3 view using the WebGrid helper. Below are the Car and it's metadata class.

车类：

[MetadataType(typeof(CarMetadata))]
public partial class Car
{
    // car implementation
}

租车元数据类：

public class CarMetadata
{        
    [DisplayName("Car Name")]
    [StringLength(100, ErrorMessageResourceType = typeof(ValidationText), ErrorMessageResourceName="CarNameDescriptionLength")]
    [Required]
    public string CarName { get; set; }    
}

查看内容：

@model List<Car>
...
var grid = new WebGrid(Model, canPage: true, rowsPerPage: 10);
grid.Pager(WebGridPagerModes.NextPrevious);

@grid.GetHtml(
    htmlAttributes: new { id = "grid" },
    columns: grid.Columns(
        grid.Column("CarName", ?????)
    ));

目标：我想弄清楚如何使用数据显示名称注释作为的WebGrid列标题的文本（ ????? ）。有谁知道这是如何实现的？

GOAL: I'd like to figure out how to use the DisplayName data annotation as the column header text in the WebGrid (?????). Does anyone know how this is accomplished?

在此先感谢！

推荐答案

丑陋不堪，地狱，但它可以工作：

Ugly as hell but it could work:

grid.Column(
    "CarName", 
    ModelMetadata.FromLambdaExpression(
        car => car.CarName, 
        new ViewDataDictionary<Car>(new Car())
    ).DisplayName
)

问题是，在助手的WebGrid完全是基于动态数据，绝对没有强类型，这就是为什么我讨厌它的原因之一。该WebMatrix的团队在微软必须在C＃4.0的动态功能的真正的球迷为他们的整个API仅需弱类型的对象： - ）

The problem is that the WebGrid helper is entirely based on dynamic data, absolutely no strong typing and that's one of the reasons why I hate it. The WebMatrix team at Microsoft must be real fans of the C# 4.0 dynamic feature as their entire API takes only weakly typed objects :-)
