Asp.net mvc 单选按钮检索选定的数据

Question

我正在使用带有 razor 和 javascript 的 ASP.net MVC4。

我加载我的视图如下： 当Retrieve data from database不检查radiobutton的值时，radiobutton是空的，我该如何解决这个问题？ Textbox中的值都是回收的radiobutton号。

    <table>
    <tr>
        <th>Parte Frontal</th>
        <th>Cant.</th>
        <th>Bueno</th>
        <th>Regular</th>
        <th>Deficiente</th>
        <th>Observaciones</th>
    </tr>      
    @{int numitem = 0;} 
    @for (var i = 0; i < ViewBag.DatosExtFrontal.Count; i++)
    {                                          
        <tr>            
        <td>@ViewBag.DatosExtFrontal[i].cprp_descripcion</td>
        <td>@Html.TextBox(string.Format("txtpieza{0}", numitem), (int)ViewBag.DatosExtFrontal[i].piv_cantidad, new { id = string.Format("txtpieza{0}", ViewBag.DatosExtFrontal[i].cprp_idpartepre.ToString()), style = "width:25px;text-align:right;", onkeyup = "checkInt(this)", sololectura = false })</td>       
        <td class="td-center">               
            @Html.RadioButton(String.Format("rbtestado{0}", numitem), "B", new { id = string.Format("B{0}", ViewBag.DatosExtFrontal[i].cprp_idpartepre.ToString()), sololectura = false })                                
        </td>
        <td class="td-center">
            @Html.RadioButton(String.Format("rbtestado{0}", numitem), "R", new { id = string.Format("R{0}", ViewBag.DatosExtFrontal[i].cprp_idpartepre.ToString()), sololectura = false })                                
        </td>
        <td class="td-center">
            @Html.RadioButton(String.Format("rbtestado{0}", numitem), "D", new { id = string.Format("D{0}", ViewBag.DatosExtFrontal[i].cprp_idpartepre.ToString()), sololectura = false })                                
        </td>                
        <td>@Html.TextBox(string.Format("txtobservacion{0}", numitem), (string)ViewBag.DatosExtFrontal[i].piv_observacion, new { id = string.Format("txtobservacion{0}", ViewBag.DatosExtFrontal[i].cprp_idpartepre.ToString()), style = "width:150px;", sololectura = false })</td>
        <td>
        @{                  
            string IdPartePre = String.Format("{0}", numitem);
            string PartePre = String.Format("{0}", (int)ViewBag.DatosExtFrontal[i].cprp_idpartepre);
            numitem++;             
        }  
        <input id="@IdPartePre" type="hidden" name="@PartePre" value="@PartePre"/>
        </td>
        </tr>     

    } 
    </table>

如果您不能使用 for 助手将其绑定到您的模型，那么您将需要在该字段上放置一个唯一名称，然后您可以使用控制器获取值

Request.Form["RadioName"].ToString()
