为什么 DisplayFormat DataFormatString 不起作用? [英] Why is DisplayFormat DataFormatString not working?

问题描述

我的视图模型中有一个属性如下:

I have a property in my view model as follows:

[Editable(false)]
[Display(Name = "Date")]
[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}", ApplyFormatInEditMode = true)]
public DateTime MovementDate { get; set; }

还有标记

<td>
    @Html.DisplayFor(modelItem => item.MovementDate)
</td>

将日期值呈现为 2013/05/15 12:00:00 AM.

我做错了什么?我的模型:

What am I doing wrong? My model:

public class WithDateModel
{
    [DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}")]
    public DateTime TheDate { get; set; }
    public WithDateModel()
    {
        TheDate = DateTime.Now;
    }
}

我的观点:

@model ParkPay.WebTests.Models.WithDateModel
@Html.DisplayFor(m => m.TheDate)
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

渲染的内容:

2013/05/25 02:23:37 AM

推荐答案

如果您设置了 [Editable(false)]，为什么还要使用 ApplyFormatInEditMode?所有 ApplyFormatInEditMode 所做的就是格式化日期，如果您将日期放在文本框中或用于编辑的东西中，由于上述原因，您可能不会这样做.

Why are you using ApplyFormatInEditMode if you have set ? All ApplyFormatInEditMode does is format the date if you have it in a text box or something for editing, which you probably won't because of the aforementioned.

我能够使用以下方法正确显示日期:

I was able to get the date to display correctly using the following:

[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}")]
public DateTime Date 
{
    get
    {
        return DateTime.Now;
    }
    set
    {
        Date = DateTime.Now;
    }
}

并在视图中(带有结果输出):

and in the view (with resulting output):

@Html.DisplayFor(x => x.Date)        // 2013/05/23
<br />
@Model.Date                          // 23/05/2013 09:57:56
<br />
@Html.DisplayFor(x => Model.Date)    // 2013/05/23

希望这会有所帮助.
