Question

我曾尝试使用Requiredif和RequiredifTrue，但两者都无效。下面是我的代码。当我将IsmedicalInsurance的值设为true / false时，其他两个都无法正常工作。

[Required(ErrorMessage="Please update about medical insurance")]
    public bool? IsMedicalInsurance { set; get; } 

[RequiredIf("IsMedicalInsurance", true, ErrorMessage = "Enter Primary Insuracne Name")]
    public string PrimaryInsurance { set; get; }

[RequiredIfTrue("IsMedicalInsurance", ErrorMessage = "Enter Id number")]
     public string IDnumber { set; get; }

查看代码。

<label class="radio-inline">
@Html.RadioButtonFor(m => m.IsMedicalInsurance, true, new { id="rdhaveinsur"}) Yes  
</label>
<label class="radio-inline">
  @Html.RadioButtonFor(m => m.IsMedicalInsurance, false, new { id="rdhaveno"})No
  @Html.ValidationMessageFor(m => m.IsMedicalInsurance)
 </label>


<div class="col-sm-7">
  @Html.TextBoxFor(m => m.PrimaryInsurance, new { @class = "form-control", id =  "txtInsurance" })
@Html.ValidationMessageFor(m => m.PrimaryInsurance)
</div>

<div class="col-sm-7">
 @Html.TextBoxFor(m => m.IDnumber, new { @class = "form-control", id = "txtIdNumber" })
 @Html.ValidationMessageFor(m => m.IDnumber)
 </div>

为什么你需要让IsMedicalInsurance可以为空，因为该值为true，不应为null？我已经尝试了你的代码，它正在使用IsMedicalInsurance更改为bool而不是bool

你是否在脚本下面加载了？

@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/jqueryval")
@Scripts.Render("~/Scripts/mvcfoolproof.unobtrusive.min.js")

使用mvc4进行MVC万无一失的验证
