使用mvc3获取根据数据库中的值选择的单选按钮

Question

我在创建视图中有一个单选按钮列表。它在选择下拉列表时与复选框一起生成。

@model IEnumerable<Admin.Models.viewmodel> 
@foreach (var item in Model) 
{ 
    <label> 
      @Html.CheckBox("User", item.Selected, new { @id = "User" + item.Value, @value = item.Value }) 
      @item.Text 
    </label> 
    <label> 
     @Html.RadioButton("rdnUser" + item.Value.TrimStart(), 1, item.IsSelected,new { @id = "rdnUser"})Primary     

    </label> 
    <label> 
     @Html.RadioButton("rdnUser" + item.Value.TrimStart(), 2,item.IsSelected, new { @id = "rdnUser"})Secondary 
    </label> 
} 

Iam将单选按钮的值保存到表UserMapping中的字段UserType。

当我点击编辑链接，我想根据数据库值选择的单选按钮..

创建一个视图模型采取复选框，并radiobutton.viewpartial视图模型数值是： -

public class viewpartial : System.Web.Mvc.SelectListItem 
    { 
     public int Values { get; set; } 
     public bool IsSelected { get; set; } 
    } 

查询是： -

var query = (from u in UserMapping 
           where u.UserID == id && u.Active == 1 
           join f in Financial on u.FinancialID equals f.FinancialID 
           into c 
           from d in c.DefaultIfEmpty() 
           select new viewpartialIFC 
           { 
            Text = d.FiName, 
            Value = SqlFunctions.StringConvert((double)d.FinancialID), 
            Selected = d.FinancialID == u.FinancialID ? true : false, 
            Values = u.UserType, 
            //IsSelected=??? 
           }).Distinct().ToList(); 

我应该在查询什么样的变化得到单选按钮选择..

Answer 1

这是你可以创建一个用户列表，并可以选择它们选择（复选框），并选择一个特定的角色（单选按钮）的方式：

视图模型：

public class AdminViewModel 
{ 
    public int Id { get; set; } 
    public string Name { get; set; } 
    public bool isSelected { get; set; } 
    public int RadioValue { get; set; } 
} 

控制器：

public class HomeController : Controller 
{ 
    public ActionResult Index() 
    { 
    var data = GenerateViews(); 

    return View(data); 
    } 

    [HttpPost] 
    public ActionResult Index(IList<AdminViewModel> data) 
    { 
    var selectedViews = data.Where(d => d.isSelected == true); 

    foreach (var selected in selectedViews) 
    { 
     //selected.Id; 
     //selected.RadioValue; 
    } 

    System.Diagnostics.Debugger.Break(); 

    return View(data); 
    } 

    private IList<AdminViewModel> GenerateViews() 
    { 
    var output = new List<AdminViewModel>(); 
    var rand = new Random(); 

    for (var count = 1; count <= 10; ++count) 
    { 
     var newView = new AdminViewModel(); 

     newView.Id = count; 
     newView.Name = "Name " + count.ToString(); 
     newView.isSelected = false; 
     newView.RadioValue = rand.Next(1, 3); 

     output.Add(newView); 
    } 

    return output; 
    } 
} 

查看：

@model IList<WebMVC3.Controllers.AdminViewModel> 

<h2>Index</h2> 

@using (Html.BeginForm()) 
{ 

    //foreach (var item in Model) 
    for(var index = 0; index < Model.Count; ++index) 
    { 
    <div> 
     @Html.HiddenFor(m => Model[index].Id) 
     <label> 
     @Html.CheckBoxFor(m => Model[index].isSelected, Model[index].isSelected) 
     @Model[index].Name 
     </label> 
     <label> 
     @Html.RadioButtonFor(m => Model[index].RadioValue, 1) 
     Primary 
     </label> 
     <label> 
     @Html.RadioButtonFor(m => Model[index].RadioValue, 2) 
     Secondary 
     </label> 
    </div> 
    } 
    <input type="submit" value="Save" /> 
}
