ValidationSummary和ValidationMessageFor在没有错误时显示自定义CSS

Question

一旦我将自定义CSS应用于ValidationSummary和ValidationMessageFor,即使没有错误,它也会出现在页面上.CSS确实有一个图像.

如果没有错误,如何隐藏摘要和错误？

@Html.ValidationSummary("", new { @class = "required" })
@Html.ValidationMessageFor(m => m.UserName, null, new { @class = "required" })


.required {
    background-image: url(/images/required.jpg);
    background-repeat: no-repeat;
    height: 33px;
    width: 386px;
    font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
    font-size: 13px;
    font-weight: bold;
    color: #1eb4ec;
    padding-top: 16px;
    padding-left: 54px;
    margin-left: 30px;
}

这些已经内置了css类型:

/* Styles for validation helpers
-----------------------------------------------------------*/
.field-validation-error {
    color: #ff0000;
}

.field-validation-valid {
    display: none;
}

.input-validation-error {
    border: 1px solid #ff0000;
    background-color: #ffeeee;
}

.validation-summary-errors {
    font-weight: bold;
    color: #ff0000;
}

.validation-summary-valid {
    display: none;
}

在MVC3项目的默认css文件中.这些是根据指定的或是否ModelState有任何错误而适当显示Property的ValidationSummary.如果没有错误,ModelState那么display:none;from .field-validation-valid将隐藏错误.
