复选框和下拉列表的自定义验证

Question

我在我的某个表单上使用DataAnnotations进行验证。字符串类型的验证是可以的。它适用于必需和错误消息。但是在验证复选框时我遇到了问题。我有某种规范/规则，如。

我有一组包含4个复选框的复选框。我想验证它，以便至少选择一个复选框，这是必须的。 但就性别而言，应该标记性别，但一次只应检查一个性别。  我怎样才能在Mvc中实现这一目标。

我发现另外一个难以验证的字段，那就是与ViewBag捆绑在一起的Dropdownlist。如果Dropdown与Viewbag捆绑在一起，如何使用dataAnnotations验证下拉列表。我正在使用一个隐藏字段来发布Dropdownlist.Below的值是我的代码::

我真的很难找到解决方案。

View Page
@{
    ViewBag.Title = "Home Page";
}
@model MvcValidation.Models.Model
<script src="~/Scripts/jquery-1.7.1.min.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>


<style type="text/css">
    #DataContent
    {
        width: 100%;
        height: 1000px;
    }

    .Contentdiv
    {
        float: left;
        width: 100%;
        height: 100%;
    }

    .HeadingDiv
    {
        float: left;
        width: 100%;
        padding-bottom: 2%;
    }

    .CommonDiv
    {
        float: left;
        width: 100%;
    }

    .LeftDiv
    {
        float: left;
        width: 50%;
    }
</style>
