MVC2-两个单选按钮组保持状态

您是使用MVC的ValidationMessage助手验证客户端还是在控制器中验证客户端?如果您发布页面并使用模型状态.IsValid在控制器上,确保返回具有相同实体的视图。

是否将默认单选按钮设置为on文件准备就绪(…)或使用JQuery/Javascript在客户端加载(…)?否则,我已经测试了以下内容,它工作正常,单选按钮状态保持不变:

 public class MyModel
    {
        [Required(ErrorMessage="Name is required")]
        public string Name { get; set; }
        public bool IsSelected { get; set; }
    }

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TestSample.Models.MyModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Home Page
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<%Html.BeginForm(); %>
<%Html.EnableClientValidation(); %>
        <p>
        <%=Html.RadioButtonFor(m=>m.IsSelected,"true") %>
        <%=Html.RadioButtonFor(m=>m.IsSelected,"false") %>
        <%=Html.TextBoxFor(m => m.Name) %>
        <%=Html.ValidationMessageFor(m => m.Name, "Required") %>
        <input type="submit" id="btnSubmit" name="name" value="Submit" />
        </p>
<%Html.EndForm(); %>
    <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
      </asp:Content>

[HttpPost]
public ActionResult Index(MyModel model)
  {
       if (ModelState.IsValid)
       {//Your code goes here }
       return View(model);
  }
