我应该如何使用EditorFor（）在MVC的货币/货币类型？

问题描述

在我看来，我有以下电话。

 ＆LT;％= Html.EditorFor（X =＆GT; x.Cost）％GT;
 

我有以下code一个ViewModel定义成本。

 公共小数成本{搞定;组; }
 

然而，这显示小数（如0.0000）后，用四位数字的十进制值。我知道 Decimal.ToString的（G）的（），这似乎解决了这个问题，但我不确定在哪里应用它。

一个解决方案似乎是创建一个局部视图Currency.aspx。

 ＆LT;％@控制语言=C＃继承=System.Web.Mvc.ViewUserControl＆LT;＆十进制GT; ％GT;
＆LT;％= Html.TextBox（Model.ToString（G），新{@class =货币}）％GT;
 

和一个 [UIHint（货币）] 在我的视图模型。

这看起来不太优雅。我认为这个问题已经解决了MVC框架或C＃整齐的地方，但我不知道更清洁的解决方案。

什么是处理MVC编辑货币值的适当方法？

解决方案

  [DisplayFormat（DataFormatString ={0：F2}，ApplyFormatInEditMode = TRUE）]
公共小数成本{搞定;组; }
 

和在您的视图：

 ＆LT;％= Html.EditorFor（X =＆GT; x.Cost）％GT;
 

和这一切。

您可能希望应用自定义CSS类。你可以这样做：

 ＆LT; D​​IV CLASS =货币＆GT;
    ＆所述;％= Html.EditorFor（X =＆GT; x.Cost）％GT;
＆LT; / DIV＆GT;
 

然后在你的CSS：

  .currency输入{
    / **一些CSS规则** /
}
 

或write自定义DataAnnotationsModelMetadataProvider 这将允许您：

  [DisplayFormat（DataFormatString ={0：F2}，ApplyFormatInEditMode = TRUE）]
[HtmlProperties（的CssClass =货币）]
公共小数成本{搞定;组; }
 

，然后在您的视图：

 ＆LT;％= Html.EditorFor（X =＆GT; x.Cost）％GT;
 

In my view I have the following call.

<%= Html.EditorFor(x => x.Cost) %>

I have a ViewModel with the following code to define Cost.

public decimal Cost { get; set; }

However this displays a decimal value with four digits after the decimal (e.g. 0.0000). I am aware of Decimal.toString("G") (MSDN) which appears to solve this issue, but I'm uncertain of where to apply it.

One solution seems to be create a partial view "Currency.aspx".

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Decimal>" %>
<%= Html.TextBox(Model.ToString("g"), new { @class = "currency" }) %>

And a [UIHint("Currency")] in my ViewModel.

This seems inelegant. I assume that this problem has been solved tidily somewhere in the MVC framework or C# but I am unaware of cleaner solutions.

What is the appropriate way to handle editing currency values in MVC?

解决方案

[DisplayFormat(DataFormatString = "{0:F2}", ApplyFormatInEditMode = true)]
public decimal Cost { get; set; }

and in your view:

<%= Html.EditorFor(x => x.Cost) %>

and that's all.

You will probably want to apply a custom CSS class. You could do this:

<div class="currency">
    <%= Html.EditorFor(x => x.Cost) %>
</div>

and then have in your css:

.currency input {
    /** some CSS rules **/
}

or write a custom DataAnnotationsModelMetadataProvider which will allow you to:

[DisplayFormat(DataFormatString = "{0:F2}", ApplyFormatInEditMode = true)]
[HtmlProperties(CssClass = "currency")]
public decimal Cost { get; set; }

and then in your view:

<%= Html.EditorFor(x => x.Cost) %>
