Question

I have jquery validation(With twitter bootstrap) on my page and I use the following ASP.NET MVC annotation.

[DisplayName("Text)"),Range(100,35000)]
    public decimal Field { get; set; }

The element is added with:

@Bootstrap.TextBoxFor(x => x.Field, htmlAttributes: new {@class="ignore",id="field" })

The problem is that I want to allow an empty value in this field but keep the range validation in case a non empty value in written.

This is my javascript code:

$("#Field").on("keyup", function (e) {
        e.preventDefault();
        if ($(this).val() == "") {
            $(this).removeClass("input-validation-error");
            $(this).addClass("valid");
            $(this).next().html("");
            $(this).parent().parent().removeClass("error");
        }
    })

    $.validator.setDefaults({ ignore: ".ignore" });

I found the solution…If you make the type nullable it works…

[DisplayName("Text)"),Range(100,35000)]
public decimal? Field { get; set; }

Thank you for your help!
