I use Jquery MaskMoney in my inputs to treat decimais , so far so good, but I noticed that when I type values above 1,000,00 But when the value is a thousand where the point (999.99) does not go, the value arrives correct in MaskMoney follow my Bind and my Mvc :

Controller

[HttpPost]
public ActionResult Editar(Produto produto, string returnUrl)
{
    TempData["mensagem"] = "PRODUTO EDITADO COM SUCESSO!";
    if (!String.IsNullOrEmpty(produto.Cest))
    {
        produto.Cest = produto.Cest.Replace(".", "");
    }
    produto.Codigo = produto.Codigo.Split(Convert.ToChar("."))[1];
    ctx.Entry(produto).State = EntityState.Modified;
    ctx.SaveChanges();
    return Redirect("~" + returnUrl);
    //  return RedirectToAction("sucesso", "produto");
}

Controller

public decimal Custo { get; set; }

Model

<div class="col-lg-2">
   <label for="Custo">Custo</label>
   @Html.TextBoxFor(model => model.Custo, new { @class = "form-control decimal required" })
</div>

c# asp.net mvc

You will have to create your own Model Binder to handle this specific case of decimal number localization (Brazilian formatting).

follows an example class for this decimal model binder:

using System;
using System.Globalization;
using System.Web.Mvc;

public class DecimalModelBinder : IModelBinder {
    public object BindModel(ControllerContext controllerContext, 
        ModelBindingContext bindingContext) {
        ValueProviderResult valueResult = bindingContext.ValueProvider
            .GetValue(bindingContext.ModelName);
        ModelState modelState = new ModelState { Value = valueResult };
        object actualValue = null;
        try {
            actualValue = Convert.ToDecimal(valueResult.AttemptedValue, 
                CultureInfo.CurrentCulture);
        }
        catch (FormatException e) {
            modelState.Errors.Add(e);
        }

        bindingContext.ModelState.Add(bindingContext.ModelName, modelState);
        return actualValue;
    }
}

This class is extracting a decimal value from the parameters of the posted form and transforming it into decimal

Then, in order for MVC to use its binder class, simply add that line to the% method of% pain file Application_Start

like this:

protected void Application_Start() {
    AreaRegistration.RegisterAllAreas();

    ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder());

    // All that other stuff you usually put in here...
}

If you'd like to read more about this solution, have some more explanation, I found it on Phil Haack's blog: Model Binding Decimal Values
