Using Html.EditorFor() for custom type in ASP.NET MVC

Question

I have a custom type Money for my ViewModel:

public class Money { public Money(decimal value) { Value = value; } public decimal Value { get; private set; } public override string ToString() { return string.Format("{0:0.00}", Value); } } 

and I want to render a textbox in ASP.NET MVC via HTML.EditorFor(viewModel => viewModel.MyMoneyProperty) but it doesn't work. Is there a special interface which I have to implement in Money?

Best regards and thanks in advance,

Steffen

Try like this:

public class Money { public Money(decimal value) { Value = value; } [DisplayFormat(DataFormatString = "{0:0.00}", ApplyFormatInEditMode = true)] public decimal Value { get; private set; } } 

and in your view:

<%= Html.EditorFor(x => x.SomePropertyOfTypeMoney.Value) %> 

Or you could have a custom editor template for Money (~/Views/Shared/EditorTemplates/Money.ascx):

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<AppName.Models.Money>" %> <%= Html.TextBox("", Model.Value.ToString("0.00")) %> 

and then in your view:

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