我在ComponentParameters 列表中使用 EditorFor（如下所示）。编辑器模板根据值切换，日期时间不起作用。当我在回发之前查看 HTML 时，值在那里，但在List<ComponentParameter>模型内部，与日期时间对应的点为空。

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

编辑器模板：

@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">

再次查看 HTML，问题在于 Html 助手也试图绑定到模型，如id="ComponentList_0__ComponentParameterList_0_". 由于错误，这似乎导致该模型根本不绑定。

由于我只是想使用一些输入字段，因此我删除了这些并用常规 HTML 替换它们<input>。
