Asp.Net MVC中的步骤向导无意中使用上一页按钮

Question

我正在按照本指南here创建一个步骤向导来遍历多个页面，每个页面都有表单，同时保存每个表单数据以存储在我的数据库中，但我遇到的问题是在第二页上详细地址'。当我按prevBtn返回上一页'basicDetails'时，我的表单正在尝试进行客户端验证，我得到所有验证错误，而不是发布到我的操作方法，看看是否按下了prevBtn或nextBtn

这是我的地址详细信息页面

<div class="col-sm-7 col-sm-offset-1">
  @using (Html.BeginForm("AddressDetails", "User", FormMethod.Post)) {
  <div class="row">
    <h3>What's the address for this payout method?</h3>
  </div>

  <div class="row">
    <div class="form-group">
      <label for="AddressLine1">Street address</label> 
      @Html.TextBoxFor(m => m.StreetAddressLine1, new { @id = "AddressLine1", @class = "form-control input-lg", placeholder = "e.g. 123 Main St." }) @Html.ValidationMessageFor(m => m.StreetAddressLine1,
      "", new { @class = "text-danger" })
    </div>
  </div>

  <div class="row">
    <div class="form-group">
      <label for="AddressLine2">Apt, suite, bldg. (optional)</label> 
      @Html.TextBoxFor(m => m.StreetAddressLine2, new { @id = "AddressLine2", @class = "form-control input-lg", placeholder = "e.g. Apt #6" }) @Html.ValidationMessageFor(m => m.StreetAddressLine2,
      "", new { @class = "text-danger" })
    </div>
  </div>


  <div class="row">
    <div class="col-sm-6" style="padding-left: 0px; padding-right: 5px;">
      <div class="form-group">
        <label for="City">City</label> @Html.TextBoxFor(m => m.City, new { @id = "City", @class = "form-control input-lg" }) 
        @Html.ValidationMessageFor(m => m.City, "", new { @class = "text-danger" })
      </div>
    </div>
    <div class="col-sm-6" style="padding-left: 5px; padding-right: 0px;">
      <div class="form-group">
        <label for="State">State / Province</label> 
        @Html.DropDownListFor(m => m.StateCode, new SelectList(Model.StateList, "Value", "Text"), "", new { @id = "State", @class = "btn-group-lg countryList form-control selectpicker" }) @Html.ValidationMessageFor(m
        => m.StateCode, "", new { @class = "text-danger" })
      </div>

    </div>
  </div>

  <div class="row">
    <div class="form-group">
      <label for="PostalCode">Zip code / Postal code</label> 
      @Html.TextBoxFor(m => m.PostalCode, new { @id = "PostalCode", @class = "form-control input-lg", placeholder = "e.g. 94102" }) @Html.ValidationMessageFor(m => m.PostalCode, "", new { @class =
      "text-danger" })
    </div>
  </div>

  <div class="row">
    @Html.DropDownListFor(m => m.SelectedCountryId, new SelectList(Model.CountryList, "Value", "Text"), new { @id = "Country", @class = "btn-group-lg countryList form-control selectpicker" })
  </div>

  <div class="row">
    <hr />
  </div>

  <div class="row">

    <div class="col-sm-12">
      <input type="submit" name="prevBtn" value='Previous' />
      <input type="submit" name="nextBtn" value='Next' />
    </div>

  </div>
  }
</div>

这是我的行动方法

[HttpPost]
    public ActionResult AddressDetails(UserAddressViewModel addressViewModel, string prevBtn, string nextBtn)
    {

        YogaProfileBankAccount obj = GetBankAccount();

        if (prevBtn != null)
        {
            UserBillingViewModel billingViewModel = new UserBillingViewModel();
            //bd.CustomerID = obj.CustomerID;
            //bd.CompanyName = obj.CompanyName;

            return View("BasicDetails", billingViewModel);
        }

        if (nextBtn != null)
        {
            if (ModelState.IsValid)
            {
                //obj.Address = data.Address;
                //obj.City = data.City;
                //obj.Country = data.Country;
                //obj.PostalCode = data.PostalCode;

                return View("AccountDetails");
            }
        }
        return View();
    }

因此，当我按下之前会发生的情况，所有字段都会尝试验证
