DisplayFormat not getting applied on decimal value
提问by Jerad Rose
I have a model property I'm trying to render using an EditorFor template, and I'm trying to apply formatting using the DisplayFormat attribute. However, it's not working at all -- it's totally being ignored.
我有一个模型属性，我正在尝试使用 EditorFor 模板呈现，并且我正在尝试使用 DisplayFormat 属性应用格式。然而，它根本不起作用——它完全被忽略了。
Here is my template:
这是我的模板：
@model System.Decimal?
@Html.TextBoxFor(m => m)
Here is my model:
这是我的模型：
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:0.00}")]
public decimal? Retail { get; set; }
Here is my view:
这是我的观点：
@Html.EditorFor(m => m.Retail)
But it's rendering a textbox with the following value:
但它渲染了一个具有以下值的文本框：
189.9900
189.9900
It seems pretty straight forward, but it's not working, and I have no idea why.
这看起来很简单，但它不起作用，我不知道为什么。
UPDATE:Just for kicks, I tried it with a DisplayFor template, and it worked:
更新：只是为了踢球，我用 DisplayFor 模板试了一下，它有效：
@Html.DisplayFor(m => m.Retail)
So why would the DisplayFor template work, but not the EditorFor template, when I've set ApplyFormatInEditModeto true?
那么当我设置ApplyFormatInEditMode为 true时，为什么 DisplayFor 模板可以工作，而 EditorFor 模板不行？
UPDATE 2:Never mind, the reason that worked is because my Decimal display template was hard-coded to format that way. So my display template also does not work.
更新 2：没关系，有效的原因是因为我的十进制显示模板是硬编码的。所以我的显示模板也不起作用。

Darin Dimitrov 发布了这个答案，我能够使用他的解决方案让它工作：
@Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue)
A bit crude, IMO, that this doesn't work w/ TextBoxFor, but at least it works.
有点粗糙，IMO，这对 w/ 不起作用TextBoxFor，但至少它有效。

DisplayFormatwon't work like that; if you manually create a text box for the property it doesn't come into play. It would only work if you did
DisplayFormat不会那样工作；如果您手动为该属性创建一个文本框，它就不会起作用。只有当你这样做时它才会起作用
@model System.Decimal?
@Html.DisplayFor(m => m)

Try with this format, it outputs 18.999,00
试试这种格式，它输出 18.999,00
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:N}")]
