在MVC中構建頁面期間丟失隱藏字段3

Question

我有一個基本上是三階段嚮導的頁面。我創建了一個類來保存頁面上的所有字段，並隱藏三個DIV中的兩個，使它們依次可見。 我使用一個名爲「wiz」的變量來跟蹤我在哪個階段。

申請2的3

然而，即使在標籤顯示來自控制器的正確的值旅行通階段..

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

..隱藏字段下方保持不同的價值！我看不到這是什麼原因造成的。

<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="" /> 

這看起來沒有任何意義。

<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() 

爲什麼wiz變量顯示爲2但隱藏爲1？我很難過。

下面是使用的類。
