ASP MVC 5 - 頁上的兩種形式

我有兩種形式在ASP MVC 5中創建的網頁。 Screan of page ASP MVC 5 - 頁上的兩種形式

第一個「LoginPanel」是局部視圖，類似這樣的

@model UowTest.Models.LoginPanelModel 

@using (Html.BeginForm("LoginPanel", "Account", FormMethod.Post, new { @class = "navbar-form navbar-left" })) 
{ 
    if(!Model.IsLogin) 
    { 
     <div class="form-group"> 
      @Html.TextBoxFor(m => m.Login, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.Login) }) 
     </div> 
     <div class="form-group"> 
      @Html.PasswordFor(m => m.Password, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.Password) }) 
     </div> 
     <button type="submit" class="btn btn-default">Zaloguj</button> 
    } 
    else 
    { 
     <ul class="nav navbar-nav navbar-left"> 
      <li><span>Witaj</span></li> 
      <li><a href="#">@Model.UserName</a></li> 
     </ul> 
    } 
}

被添加到_Layout.cshtml在頂板部：

<body> 
    <div class="navbar navbar-inverse navbar-fixed-top"> 
     <div class="container"> 
      <div class="navbar-header"> 
      ... 
      </div> 
      <div class="navbar-collapse collapse"> 
       <ul class="nav navbar-nav navbar-right"> 
        <li>@Html.Action("LoginPanel", "Account")</li> 
       </ul> 
      </div> 
     </div> 
    </div> 
</body>

中的AccountController

我有HTTP GET和Post方法：

public ActionResult LoginPanel() 
{ 
    return PartialView(new LoginPanelModel()); 
} 

[HttpPost] 
public ActionResult LoginPanel(LoginPanelModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     return RedirectToAction("Index", "Home"); 
    } 

    return RedirectToAction("Login", new { message = "Login lub hasło jest nieprawidłowe!" }); 
}

它工作得很好，直到我說像註冊視圖：

@model UowTest.Models.RegisterModel 

@{ 
    ViewBag.Title = "Register"; 
} 

@using (Html.BeginForm("Register", "Account", FormMethod.Post)) 
{ 
    <div class="form-group"> 
     @Html.LabelFor(m => m.Login) 
     @Html.TextBoxFor(m => m.Login, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.Login) }) 
    </div> 
    <div class="form-group"> 
     @Html.LabelFor(m => m.Password) 
     @Html.PasswordFor(m => m.Password, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.Password) }) 
    </div> 
    <div class="form-group"> 
     @Html.LabelFor(m => m.RepeatedPassword) 
     @Html.PasswordFor(m => m.RepeatedPassword, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.RepeatedPassword) }) 
    </div> 
    <div class="form-group"> 
     @Html.LabelFor(m => m.FirstName) 
     @Html.TextBoxFor(m => m.FirstName, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.FirstName) }) 
    </div> 
    <div class="form-group"> 
     @Html.LabelFor(m => m.LastName) 
     @Html.TextBoxFor(m => m.LastName, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.LastName) }) 
    </div> 
    <div class="form-group"> 
     @Html.LabelFor(m => m.Email) 
     @Html.TextBoxFor(m => m.Email, new { @class = "form-control", @placeholder = Html.PlaceholderFor(m => m.Email) }) 
    </div> 
    <button type="submit" class="btn btn-default">Zarejestruj</button> 
}

用的AccountController方法：

public ActionResult Register() 
{ 
    return View(new RegisterModel()); 
} 

[HttpPost] 
public ActionResult Register(RegisterModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     return RedirectToAction("Login"); 
    } 

    return View(model); 
}

當我擊註冊按鈕，它會調用

[HttpPost] 
public ActionResult Register(RegisterModel model)

當ModelState中不有效的我返回寄存器視圖來顯示驗證消息，但insted的看到這個頁面，有什麼叫

[HttpPost] 
public ActionResult LoginPanel(LoginPanelModel model)

什麼原因錯誤：

在_Layout.cshtml符合在其中創建登錄局部視圖。

嘗試返回PatrialView而不是視圖。

[HttpPost] 
public ActionResult Register(RegisterModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     return RedirectToAction("Login"); 
    } 

    return PartialView(model); 
}

這不是一個解決方案，因爲當我返回PartialView頁面不使用我的layaut和註冊頁面是醜陋的，但錯誤沒有發生。 – user1988350

你爲什麼不讓註冊表成爲局部視圖，從你的圖像看來，註冊是一個局部視圖。 – SadiRubaiyet

註冊是標準視圖並使用_Layout女巫包含LoginPanel局部視圖。註冊爲部分視圖也許可以解決我的問題，但需要使用表單作爲部分視圖，因爲所有視圖都使用_Layout。我認爲這個問題是在LoginPanel post方法中重定向的，但是如何在模型無效後做重定向。 – user1988350
