这是我的代码,它显示我的模型中的两个单选按钮。主要问题是当我提交表单时,当我在表单提交之前选择一个单选按钮时,模型性属性变得为空。请帮我找出问题所在。
模型类
public class StudentModel
{
[Required(ErrorMessage = "First Name Required")] // textboxes will show
[Display(Name = "First Name :")]
[StringLength(5, ErrorMessage = "First Name cannot be longer than 5 characters.")]
public string FirstName { get; set; }
[Required(ErrorMessage = "Last Name Required")] // textboxes will show
[Display(Name = "Last Name :")]
[StringLength(5, ErrorMessage = "Last Name cannot be longer than 5 characters.")]
public string LastName { get; set; }
[Required(ErrorMessage = "Sex Required")]
[Display(Name = "Sex :")]
public int SexID { get; set; }
public List<Sex> Sex { get; set; }
}
public class Sex
{
public string ID { get; set; }
public string Type { get; set; }
}
Controller 类
public class HomeController : Controller
{
[HttpGet]
public ActionResult Index()
{
ViewBag.Message = "Welcome to ASP.NET MVC!";
var student = new StudentModel
{
FirstName = "Rion",
LastName = "Gomes",
//I think the best way to populate this list is to call a service here.
Sex = new List<Sex>
{
new Sex{ID="1" , Type = "Male"},
new Sex{ID="2" , Type = "Female"}
}
};
return View(student );
}
[HttpPost]
public ActionResult Index(StudentModel model)
{
if (ModelState.IsValid)
{
//TODO: Save your model and redirect
}
//Call the same service to initialize your model again (cause we didn't post the list of sexs)
return View(model);
}
}
查看代码
@model MvcRadioButton.Models.StudentModel
@Html.BeginForm()
{
<div>
@Html.LabelFor(model => model.FirstName)
@Html.EditorFor(model => model.FirstName)
@Html.ValidationMessageFor(model => model.FirstName)
</div>
<div>
@Html.LabelFor(model => model.LastName)
@Html.EditorFor(model => model.LastName)
@Html.ValidationMessageFor(model => model.LastName)
</div>
@{
foreach (var sex in Model.Sex)
{
<div>
@Html.RadioButtonFor(model => model.Sex, new { id = "sex" + sex.ID })
@Html.Label("sex" + sex.ID, sex.Type)
</div>
}
}
<input type="submit" value="Submit" />
}
如果可能,请运行我的代码并告诉我如何实现我的目标,如果有人认为这种情况可以以更好的方式处理,只需更改代码,然后请告诉我,因为我是 MVC 的新手。
最佳答案
View 模型
public class StudentModel
{
//properties
public bool Sex { get; set; }
}
查看
@using (Html.BeginForm())
{
@Html.RadioButtonFor(model => model.Sex, "false", new { id = "male" })
@Html.Label("male", "Male")
@Html.RadioButtonFor(model => model.Sex, "true", new { id = "female" })
@Html.Label("female", "Female")
<button type="submit">OK</button>
}
Controller
[HttpPost]
public ActionResult Index(StudentModel model)
{
//you can modify "model" however you want here
return Content("Sex: " + model.Sex);
}
