MVC3中使用RadioButtonFor()

创建页面  进行初始化   默认 男 被选中

<div class="label">
            <div class="editor-label">
                @Html.LabelFor(model => model.Sex)
            </div>
            <div class="radios">
              <label id="boy"> @Html.RadioButtonFor(model => model.Sex,"男", new { @id="boy",@name="sex",@checked=true})男</label>
              <label id="gril">  @Html.RadioButtonFor(model => model.Sex, "女", new { @id="gril",@name="sex"})女</label>
            </div>

        </div>

编辑页面 编辑时，绑定值，根据数据显示 RadioButtonFor自动选中状态

<div class="label">
    <div class="editor-label">
        @Html.LabelFor(model => model.Sex)
    </div>
    <div class="radios">
  <label id="boy"> @Html.RadioButtonFor(model => model.Sex,"男", new { @id="boy",@name="sex",@checked=true})男</label>
<label id="gril">  @Html.RadioButtonFor(model => model.Sex, "女", new { @id="gril",@name="sex"})女</label>

    </div>
</div>

model.Sex是int 也可以是bool  sex值是1时 男被选中 2时女被选中

<div class="label">
     <div class="editor-label">
         @Html.LabelFor(model => model.Activity)
     </div>
     <div class="radios">
         @Html.RadioButtonFor(model => model.Activity, true, new { @id = "radio3", @name = "Activity" })<label id="tr">启用</label>
         @Html.RadioButtonFor(model => model.Activity, false, new { @id = "radio4", @name = "Activity" })<label id="fl">禁用</label>
     </div>
 </div>
