這是我的看法

 <div id="Domain"> 
      <ul class="formlist"> 
       <li class="width100"> 
        <div class="form-check form-check-inline"> 
         <label class="form-check-label"> 
          @Html.RadioButtonFor(model => model.domain_flag, 1, new { @class = "form-check-input" }) <span>Yes</span> 
         </label> 
        </div> 
        <div class="form-check form-check-inline">

我的模型

public int? domain_flag { get; set; } 
    [Display(Name = "Date of Renewal")] 
    [DataType(DataType.Date)] 
    [RequiredIf("domain_flag==1",ErrorMessage ="Enter Renew Date")] 
    public DateTime? domain_renew_date { get; set; } 
    [Display(Name = "Date of Expiry")] 
    [DataType(DataType.Date)] 
    [DisplayFormat(DataFormatString = "{0:mm/dd/yy}", ApplyFormatInEditMode = true)] 
    [RequiredIf("domain_flag==1", ErrorMessage = "Enter Expiry Date")] 
    public DateTime? domain_exp_date { get; set; } 
    [Display(Name = "Vendor")] 
    [RequiredIf("domain_flag==1", ErrorMessage = "Please Select Vendor")] 
    public int? domain_vendor_id { get; set; } 
    [Display(Name = "Amount(Rs.)")] 
    [RequiredIf("domain_flag==1", ErrorMessage = "Enter Amount")] 
    [RegularExpression("^[0-9]+$", ErrorMessage = "Enter Numeric Values")] 
    public decimal? domain_amt { get; set; } 
    [Display(Name = "Comments")]   
    public string domain_remarks { get; set; } 

的Global.asax

     DataAnnotationsModelValidatorProvider.RegisterAdapter(
      typeof(RequiredIfAttribute), typeof(RequiredIfValidator)); 
     DataAnnotationsModelValidatorProvider.RegisterAdapter(
      typeof(AssertThatAttribute), typeof(AssertThatValidator)); 

在這，只要我選擇單選按鈕如果在輸入值之前顯示錯誤消息，則爲必填項。在發佈到服務器之前，應該在點擊提交按鈕時顯示錯誤消息。這可能與表達式註釋Nuget包？

是的，這可以使用ExpressiveAnnotations。

@jwaliszko提到它。

你必須在客戶端設置EA的configuation這樣的：

<script> 
    ea.settings.dependencyTriggers = '';
