如何基于复选框值验证文本框

我正在尝试根据复选框值验证文本框。 请查看我的模型类和 IsValid 覆盖方法。

public class Product
{
    //Below property value(HaveExperiance)
    [MustBeProductEntered(HaveExperiance)] 
    public string ProductName { get; set; }
    public bool HaveExperiance { get; set; }
}
public class MustBeTrueAttribute : ValidationAttribute
{
    //Here i need the value of HaveExperiance property which 
    //i passed from  [MustBeProductEntered(HaveExperiance)]  in product class above.
    public override bool IsValid(object value)
    {
        return value is bool && (bool)value;
    }
}

您可以在上面看到product类ProductName属性中，我正在尝试传递HaveExperiance类属性值，如果选中，则用户必须填写ProductName文本框。

所以我的原始问题是，我如何根据HaveExperiance值验证ProductName文本框，提前感谢。

控制器

public class HomeController : Controller
    {
        //
        // GET: /Home/
        MvcDbContext _db = new MvcDbContext();
        public ActionResult Index()
        {
          return View();
        }
        [HttpPost]
        public ActionResult Index(MyProducts model)
        {
            string ProductId = model.ProductId;
            string ProductName = model.ProductName;
            //bool remember = model.HaveExperiance;
            return View();
        }
    }

视图

@model   Mvc.Affiliates.Models.MyProducts
@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Details</h2>
<br />
<div style="height:200px; width:100%">
  @using  (Html.BeginForm("Index","Home", FormMethod.Post))
    {
   <h2>Details</h2>
        @Html.LabelFor(model => model.ProductId)
        @Html.TextBoxFor(model => model.ProductId)
        @Html.LabelFor(model => model.ProductName)
        @Html.EditorFor(model => model.ProductName)
        @Html.ValidationMessageFor(model => model.ProductName, "*")
        @Html.CheckBoxFor(model => model.HaveExperiance)
        @Html.ValidationMessageFor(model => model.HaveExperiance, "*")
       <input type="submit" value="Submit" />
  }
</div>

到目前为止，我已经尝试了上面的代码，实际上当我单击复选框时我需要，然后它应该开始验证我的产品名称文本框，如果未选中，则不。 我在上面的代码中缺少一点东西，请帮助并纠正我。
