MVC - 绑定基于复选框

Question

视图模型的特定属性我有一个这样的模型：

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; } 
} 

在我的观点：

   <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> 

等的不同的属性。

控制器是非常基本的：

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

的问题是：我想要的模型保存与物业AutonomousActivity只有当用户点击复选框IsAutonomous，或者如果复选框保存属性Employer和Position没有被检查。

我该如何做到这一点，模型活页夹能帮我吗？ 谢谢先进。

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(); 
}
