限于2位小数在TextBoxFor [英] Limit to 2 decimals in TextBoxFor

问题描述

下code工作正常，但在文本框中的十进制值的格式为0,0000
（是小数点分隔符）。我想只有2位小数。我怎样才能做到这一点？

The code below works fine but, in the textbox the decimal value has this format "0,0000" (, is the decimal separator). I'd like have only 2 decimal. How can I do this ?

谢谢，

//Database model used with NHibernate
public class Bank
{
    public virtual int Id { get; set; }
    public virtual string FirstName { get; set; }
    public virtual string LastName{ get; set; }
    public virtual decimal Amount { get; set; }
}

//MVC Model
public class MyModel
{
    public Bank Bank { get; set; }  
}

//View
@Html.TextBoxFor(m => m.Bank.Amount, new { id = "tbAmount"})

在调试器中，我看不到任何小数，wehn我一步一步做内（O @ HTML.Textbofor）认为，价值没有任何小数，但在显示页面时，有4位小数

Update 1

In the debugger, I don't see any decimal, wehn I do step by step inside (o @HTML.Textbofor) the view, the value does not have any decimal but when the page is displayed there are 4 decimals

//Database model used with NHibernate
public class Bank
{
    public virtual int Id { get; set; }
    public virtual string FirstName { get; set; }
    public virtual string LastName{ get; set; }
    public virtual decimal Amount { get; set; }
}

//Class for view
public class ViewBank
{
    [DisplayFormat(DataFormatString = "{0:n2}", ApplyFormatInEditMode = true)]
    public decimal Amount { get; set; }
}

//MVC Model
public class MyModel
{
    public Bank Bank { get; set; }      
    var ViewBank = new ViewBank() { Amount = Bank.Amount};
}

//View
@Html.TextBoxFor(m => m.Amount, new { id = "tbAmount"})

推荐答案

我会使用编辑器模板和我的不可以使用我的NHibernate领域模型中的我的看法。我将定义哪些是专门给定视图的要求（在这个情况下，限制的量，以2位小数）视图模型

I would use editor templates and I would not use my NHibernate domain models in my views. I would define view models which are specifically tailored to the requirements of the given view (in this case limiting the amount to 2 decimals):

[DisplayFormat(DataFormatString = "{0:n2}", ApplyFormatInEditMode = true)]
public decimal Amount { get; set; }

和则：

@Html.EditorFor(m => m.Bank.Amount)
