MVC - 綁定基於複選框

Question

視圖模型的特定屬性我有一個這樣的模型：

public class EmploymentVM 
{ 
    public string EmploymentType { get; set; } 
    public string Employer { get; set; } 
    public string Position { get; set; } 
    public double GrossMonthlyIncome { get; set; } 
    public DateTime? StartDate { get; set; } 
    public string AutonomousActivity { get; set; } 
} 

在我的觀點：

   <div class="form-group"> 
        @Html.LabelFor(x => x.Employer) 
        @Html.TextBoxFor(x => x.Employer, new { @class = "form-control required" }) 
       </div> 
       <div class="form-group"> 
        @Html.LabelFor(x => x.Position) 
        @Html.TextBoxFor(x => x.Position, new { @class = "form-control required" }) 
       </div> 
       <div class="form-group"> 
        @Html.LabelFor(x => x.GrossMonthlyIncome) 
        @Html.TextBoxFor(x => x.GrossMonthlyIncome, new { @class = "form-control required digits" }) 
       </div> 

等的不同的屬性。

控制器是非常基本的：

[HttpPost] 
    public ActionResult EmploymentInfo(EmploymentVM vm) 
    { 
     //the actual code to save employment 
     return View(); 
    } 

的問題是：我想要的模型保存與物業AutonomousActivity只有當用戶點擊複選框IsAutonomous，或者如果複選框保存屬性Employer和Position沒有被檢查。

我該如何做到這一點，模型活頁夾能幫我嗎？ 謝謝先進。

Answer 1

public class EmploymentVM 
{ 
public string EmploymentType { get; set; } 
public string Employer { get; set; } 
public string Position { get; set; } 
public double GrossMonthlyIncome { get; set; } 
public DateTime? StartDate { get; set; } 
public string AutonomousActivity { get; set; } 
public bool IsAutonomous { get; set; } //add in viewmodel bind it with checkbox 

} 

控制器：

public ActionResult EmploymentInfo(Employments vm) 
{ 
    if(vm.IsAutonomous) { 
    // you can set the value null/empty to any property 
     vm.Employer =null; 

    //save it 
    } 
    else { 
     // if checkbox is not checked 
     //save it 
    } 

    return View(); 
}
