MVC3 Decimal truncated to 2 decimal places on edit

Question

I\'m running MVC3 with Razor and noticed that decimal values are truncated to 2 decimal places when in edit mode. I\'ve managed to get round it by annotating my property wit

Answer 1

If you don't need the functionality of the 'EditorFor' HtmlHelper, you can simply swap it out for the 'TextBoxFor' and it shouldn't truncate your decimal value...

Answer 2

IMO, this article has a better option:

html-editorfor-with-3-decimal-places

I used this code to display up to 4 decimal digits in my EditFor:

    [Display(Name = "Discount Percentage")]
    [Range(0, 100.0)]
    [DisplayFormat(DataFormatString="{0:0.0000}", ApplyFormatInEditMode=true)]
    public Decimal? DiscountPercent { get; set; }

Answer 3

That's how the default Decimal editor template is defined:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<script runat="server">
    private object ModelValue {
        get {
            if (ViewData.TemplateInfo.FormattedModelValue == ViewData.ModelMetadata.Model) {
                return String.Format(
                    System.Globalization.CultureInfo.CurrentCulture,
                    "{0:0.00}", ViewData.ModelMetadata.Model
                );
            }
            return ViewData.TemplateInfo.FormattedModelValue;
        }
    }
</script>
<%= Html.TextBox("", ModelValue, new { @class = "text-box single-line" }) %>

Notice the {0:0.00} format.

So you have two possibilities:

1. Use double instead of decimal as type in your model

2. Modify the default editor template by creating a custom ~/Views/Shared/EditorTemplates/Decimal.cshtml which might simply look like this:

   @Html.TextBox(
       "", 
       ViewData.TemplateInfo.FormattedModelValue, 
       new { @class = "text-box single-line" }
   )
   

You probably might want to modify the display template as well.
