在MVC中构建页面期间丢失隐藏字段3

Question

我有一个基本上是三阶段向导的页面。我创建了一个类来保存页面上的所有字段，并隐藏三个DIV中的两个，使它们依次可见。 我使用一个名为“wiz”的变量来跟踪我在哪个阶段。

申请2的3

然而，即使在标签显示来自控制器的正确的值旅行通阶段..

' 
' POST: /Apply 
<HttpPost()> 
Function Apply(ByVal mdl As ApplyViewData, ByVal postbutton As Integer) As ActionResult 
.. 
mdl.wiz = 2 
.. 
Return View(mdl) 
End Function 

..隐藏字段下方保持不同的价值！我看不到这是什么原因造成的。

<h2>Apply for travel pass stage 2 of 3</h2> 

<form action="/Pass/Apply" method="post"> 

<input id="wiz" name="wiz" type="hidden" value="1" /> 
<input id="client_address" name="client_address" type="hidden" value="" /> 
<input id="client_name" name="client_name" type="hidden" value="" /> 

这看起来没有任何意义。

<h2>Apply for travel pass stage @Model.wiz of 3</h2> 

@Code 
    Html.BeginForm() 
End Code 

@Html.Hidden("wiz", Model.wiz) 
@Html.Hidden("client_address", Model.client_address) 
@Html.Hidden("client_name", Model.client_name) 

@Html.ValidationSummary() 

为什么wiz变量显示为2但隐藏为1？我很难过。

下面是使用的类。
