c# - Html.RadioButton 将所有值设置为选定值

Question

经过鼓捣解决[this][1]问题，我认为问题的核心在于:

当您将 Html.RadioButton() html 助手与枚举作为值字段一起使用时，您只能选择一次选项。重新发布页面后，助手将忽略调用中设置的值并将所有单选按钮设置为相同的值，即您在上次回发时选择的值。我做错了什么吗？

示例(观察按钮的值)

<fieldset>
    <legend>Test</legend>                            
    <div>
        <label for="SearchBag.EffectIndicatorAny" id="EffectIndicatorAnyLabel">
            Any
        </label>                
        <%=Html.RadioButton("SearchBag.EffectIndicator", "Any" , ViewData.Model.SearchBag.EffectIndicatorIsAny, new { @id = "SearchBag.EffectIndicatorAny" })%>
    </div>
    <div>
        <label for="SearchBag.EffectIndicatorSolid" id="EffectIndicatorSolidLabel">
            Solid
        </label>                
        <%=Html.RadioButton("SearchBag.EffectIndicator", "Solid", ViewData.Model.SearchBag.EffectIndicatorIsSolid, new { @id = "SearchBag.EffectIndicatorSolid" })%>
    </div>
    <div>
        <label for="SearchBag.EffectIndicatorEffect" id="EffectIndicatorEffectLabel">
            Effect
        </label>                
        <%=Html.RadioButton("SearchBag.EffectIndicator", "Effect", ViewData.Model.SearchBag.EffectIndicatorIsEffect, new { @id = "SearchBag.EffectIndicatorEffect" })%>
    </div>
</fieldset>

会生成

<fieldset>
    <legend>Effect</legend>                            
    <div class="horizontalRadio">
        <label for="SearchBag.EffectIndicatorAny" id="EffectIndicatorAnyLabel">
            Any                                      
        </label>                
        <input checked="checked" id="SearchBag.EffectIndicatorAny" name="SearchBag.EffectIndicator" type="radio" value="Any" />
    </div>
    <div class="horizontalRadio">
        <label for="SearchBag.EffectIndicatorSolid" id="EffectIndicatorSolidLabel">
            Solid
        </label>                
        <input id="SearchBag.EffectIndicatorSolid" name="SearchBag.EffectIndicator" type="radio" value="Solid" />
    </div>
    <div class="horizontalRadio">
        <label for="SearchBag.EffectIndicatorEffect" id="EffectIndicatorEffectLabel">
            Effect
        </label>                
        <input id="SearchBag.EffectIndicatorEffect" name="SearchBag.EffectIndicator" type="radio" value="Effect" />
    </div>
</fieldset>

第二次会生成:

<fieldset>
    <legend>Effect</legend>                            
    <div class="horizontalRadio">
        <label for="SearchBag.EffectIndicatorAny" id="EffectIndicatorAnyLabel">
            Any                                      
        </label>                
        <input id="SearchBag.EffectIndicatorAny" name="SearchBag.EffectIndicator" type="radio" value="Solid" />
    </div>
    <div class="horizontalRadio">
        <label for="SearchBag.EffectIndicatorSolid" id="EffectIndicatorSolidLabel">
            Solid
        </label>                
        <input checked="checked" id="SearchBag.EffectIndicatorSolid" name="SearchBag.EffectIndicator" type="radio" value="Solid" />
    </div>
    <div class="horizontalRadio">
        <label for="SearchBag.EffectIndicatorEffect" id="EffectIndicatorEffectLabel">
            Effect
        </label>                
        <input id="SearchBag.EffectIndicatorEffect" name="SearchBag.EffectIndicator" type="radio" value="Solid" />
    </div>
</fieldset>

这是由于 ASP.NET MVC Beta 代码中的一个错误。我在 asp.net MVC 论坛上写了关于这个问题的完整解释。引用这个link
