MVC隐藏字段不回发

Question

我的ComponentParameter S（如下图所示）名单上使用EditorFor。编辑器模板根据值进行切换，并且日期时间不起作用。当我在回发之前查看HTML时，值就在那里，但在模型内的List<ComponentParameter>中，与日期时间对应的点是空的。

public class ComponentParameter 
{ 
    public string Value { get; set; } 
    public string Description { get; set; } 
    public string Type { get; set; } 
    public bool Optional { get; set; } 
} 

EditorTemplate：

@switch (Model.Type.ToLowerInvariant()) 
{ 
case "datetime": 
     Html.RenderPartial("ParameterHeader", Model); 
<div class="grid_4"> 
    @{ 
     DateTime value; 
     if (!DateTime.TryParse(Model.Value, out value)) 
     { 
      value = DateTime.Today + TimeSpan.FromHours(6); 
     } 
    } 
    // Commenting out the next 2 lines causes the value to post back 
    <div class="grid_9">@Html.TextBox("", value.ToString("MM/d/yyyy"), new { @class = "date-picker autotooltip " + Model.RequiredClass, @data_mwtooltip = Model.Description })</div> 
    @Html.TextBox("", value.ToString("hh:mm tt"), new {@class="time-picker"}) 
    @Html.HiddenFor(x => x.Value, new { @class = "input-time-picker" }) 
    @Html.HiddenFor(x => x.Optional) 
    @Html.HiddenFor(x => x.Description) 
    @Html.HiddenFor(x => x.Type) 
</div> 
     break; 
case "string": 
    <div class="grid_12"> 
     @{ Html.RenderPartial("ParameterHeader", @Model); } 
@Html.TextBoxFor(x => x.Value, new { @class = "autotooltip " + Model.RequiredClass, @data_mwtooltip = Model.Description }) 
@Html.HiddenFor(x => x.Optional) 
@Html.HiddenFor(x => x.Description) 
@Html.HiddenFor(x => x.Type) 
    </div> 
     break; 
} 

HTML：

<div class="grid_4"> 
<div class="grid_9"> 
<span class="ui-spinner ui-widget ui-widget-content ui-corner-all"> 
<input id="ComponentList_0__ComponentParameterList_0_" class="time-picker ui-spinner-input valid" type="text" value="06:00 AM" name="ComponentList[0].ComponentParameterList[0]" aria-valuenow="1357041600000" autocomplete="off" role="spinbutton">

<a class="ui-spinner-button ui-spinner-down ui-corner-br ui-button ui-widget ui-state-default ui-button-text-only" tabindex="-1" role="button" aria-disabled="false"> 
</span> 
<input id="ComponentList_0__ComponentParameterList_0__Value" class="input-time-picker" type="hidden" value="07/11/2013 06:00 AM" name="ComponentList[0].ComponentParameterList[0].Value"> 
<input id="ComponentList_0__ComponentParameterList_0__Optional" type="hidden" value="False" name="ComponentList[0].ComponentParameterList[0].Optional"> 
<input id="ComponentList_0__ComponentParameterList_0__Description" type="hidden" value="Start Time" name="ComponentList[0].ComponentParameterList[0].Description"> 
<input id="ComponentList_0__ComponentParameterList_0__Type" type="hidden" value="datetime" name="ComponentList[0].ComponentParameterList[0].Type"> 
</div> 
<div class="grid_12"> 
<label> 
<input id="ComponentList_0__ComponentParameterList_5__Value" class="autotooltip paramRequired required" type="text" value="" name="ComponentList[0].ComponentParameterList[5].Value" data-mwtooltip="Attention Line" title=""> 
<input id="ComponentList_0__ComponentParameterList_5__Optional" type="hidden" value="False" name="ComponentList[0].ComponentParameterList[5].Optional"> 
<input id="ComponentList_0__ComponentParameterList_5__Description" type="hidden" value="Attention Line" name="ComponentList[0].ComponentParameterList[5].Description"> 
<input id="ComponentList_0__ComponentParameterList_5__Type" type="hidden" value="string" name="ComponentList[0].ComponentParameterList[5].Type"> 
</div> 

Answer 1

再次在HTML看，问题是，HTML辅助试图绑定到模型为好，就证明通过id="ComponentList_0__ComponentParameterList_0_"。这似乎导致该模型完全不能绑定，由于错误。

因为我只是想获得一些输入字段一起工作，我删除那些与常规的HTML <input>取而代之。
