網頁Razor 2 - 如何在回發後保留選定的選項

Question

因此，我在.NET 4.0 ASP.NET Web Pages Razor v2解決方案中擁有這個小小的cshtml頁面。

@{ 
    Layout = "~/_SiteLayout.cshtml"; 
    Page.Title = "News For All Crew"; 

    var db = Database.Open("ConnectionString");  
    var departmentsQry = "select Name from Info_Department_Names IPN order by Name";  
} 

<form method="post" action=""> 
    <select id="selectStation" name="selectStation" onchange="this.form.submit();"> 
     @foreach (var dept in db.Query(departmentsQry)) 
     { 
      <option value="@dept.Name">@dept.Name</option> 
     } 
    </select> 
</form> 

當用戶選擇一個選項時，我希望它在回發後保持選擇狀態。我該怎麼做呢？

Answer 1

@foreach (var dept in db.Query(departmentsQry)) 
{ 
    <option value="@dept.Name" selected="@(dept.Name == Request["selectStation"])">@dept.Name</option> 
}
