保存页面状态mvc4

Question

我很努力地看到如何保存一个页面状态而不做一个会话变种。 我有一个页面，其中包含一个改变页面状态的按钮，在发布后，视图可能返回，但处于错误状态。我试过ViewBag，这不能在java范围内设置。我需要一个解决方案，以节省的进行AuthType值..

@model Trakman_Portal_Administration.Models.Connection 

@ {

ViewBag.Title = "Create"; 
var conStringType = ViewBag.conStringType; 

}

@Scripts.Render("~/bundles/jquery") 

<script type='text/javascript'> 

var authType = 1 

$(document).ready(function() { 
    alert(authType); 
    if (authType == 0) { 

     $("#usernameLabel").hide(); 
     $("#usernameField").hide().find('input:text').val(""); 

     $("#passwordLabel").hide(); 
     $("#passwordField").hide().find('input:text').val(""); 

     //$("#initialCatalogLabel").show(); 
     //$("#initialCatalogField").show(); 

     document.getElementById("button1").textContent = "Intergrated"; 
     authType = 1; 
    } 
    else { 

     $("#usernameLabel").show(); 
     $("#usernameField").show(); 
     $("#passwordLabel").show(); 
     $("#passwordField").show(); 
     //$("#initialCatalogLabel").hide(); 
     //$("#initialCatalogField").hide(); 

     document.getElementById("button1").textContent = "SQL Authentication"; 
     authType = 0; 
    } 

    $("button").click(function() { 

     //$("#usernameField").attr("value",""); 
     //$("#passwordField").attr("value",""); 


     if (authType == 0) { 

      $("#usernameLabel").hide(); 
      $("#usernameField").hide().find('input:text').val(""); 

      $("#passwordLabel").hide(); 
      $("#passwordField").hide().find('input:text').val(""); 

      //$("#initialCatalogLabel").show(); 
      //$("#initialCatalogField").show(); 

      document.getElementById("button1").textContent = "Intergrated"; 
      authType = 1; 

     } 
     else { 

      $("#usernameLabel").show(); 
      $("#usernameField").show(); 
      $("#passwordLabel").show(); 
      $("#passwordField").show(); 
      //$("#initialCatalogLabel").hide(); 
      //$("#initialCatalogField").hide(); 

      document.getElementById("button1").textContent = "SQL Authentication"; 
      authType = 0; 

     } 
    }); 
}); 

<h2>Create</h2> 



@using (Html.BeginForm()) 
{ 
@Html.ValidationSummary(true) 

<fieldset> 
    <legend>connection</legend> 
    <div class="editor-label">

     @Html.ValidationMessageFor(model => model.password) 
    </div> 

    <p> 
     <input type="submit" value="Create"/> 
     @{ 
if (!string.IsNullOrEmpty(ViewBag.error)) 
{ 
       <div style="color:Red">

       </div>   
} 
     } 
    </p>

我很努力，看看如何保存页面状态而不进行会话变种

使用视图模型保留整个后背上你的信息会做的伎俩。

public class ConnectionViewModel 
{ 
    public string AuthenticationType { get; set; } 
    public string ConnectionString { get; set; } 
    ... 
} 

public ActionResult Login() 
{ 
    // pass in defaults 
    return View(new ConnectionViewModel 
    { 
     AuthenticationType = "Windows", 
     ConnectionString = "..." 
    }); 
} 

[HttpPost] 
public ActionResult Login(ConnectionViewModel viewModel) 
{ 
    // pass view model back into view to retain values 
    return View(viewModel); 
}
