asp.net - 如何在 asp.net mvc 回发期间保留部分 View 模型数据

Question

我有包含部门信息的部分 View 部门。我有员工的页面 View 。在员工 View 中，我使用部门的部分 View 来显示员工部门。我的员工模型如下

class Employee
{
  public string EmployeeName{get;set};
  public Department EmployeeName{get;set};

}

class Department
{
  public string DepartmentName{get;set};
}

我在员工页面 View 上有提交按钮。
当我提交员工 View 时，我将 Department 对象设为 null。
您能否建议我如何在回发期间获得子部门模型。
Controller 代码

[HttpGet]
        public ActionResult Employee2()
        {
            Employee e = new Employee();
            e.EmployeeName = "Prashant";
            e.Department = new Department() { DepartmentName = "Phy" };

            return View(e);
        }

        [HttpPost]
        public ActionResult Employee2(Employee e)
        {

            return View(e);
        }

先尝试搜索。这个问题之前已经被问过很多次了。

这是一种方法:

mvc partial view post

总结:将每个部分包装在多个表单标签中，每个标签都有自己的提交按钮。

但这似乎更像是您所追求的:

Post a form with multiple partial views

为此使用编辑器模板而不是部分。

您遇到的问题是，当您的 DepartmentName 文本框未正确命名以供 Controller 读取时。您的 POST将是 EmployeeName=Prashant&DepartmentName=Phy因此 Department是 null ，因此错误。
