Format decimal value with comma MVC 5

Question

I have a problem! I am using Mvc5, and I have a property like this.

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

And razor :

@Html.EditorFor(modelItem => Model.Total, new { htmlAttributes = new { @class = "form-control input-sm" } })

There is not error at this point. But if I send like 1.300,40 I getting always 0.

But if I send like 1300,40 I getting correct value. How can I solve it? I want get correct value, if I send 1300,50 or 1.300,40

You will have to add your own ModelBinder:

public class DecimalModelBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var valueResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
        var modelState = new ModelState { Value = valueResult };
        decimal actualValue = 0;

        try
        {
            actualValue = Convert.ToDecimal(valueResult.AttemptedValue,
                CultureInfo.CurrentCulture);
        }
        catch (FormatException e)
        {
            modelState.Errors.Add(e);
        }

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

and register it in your Application_Start:

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