Question

背景

我的控制器中有以下方法

[HttpGet]
 public ActionResult GetModulePropertyName(string moduleTypeValue)
 {
    var moduleKindId = _repository.GetModuleKindId(moduleTypeValue);
    var modulePropertyNames = _repository.GetModuleKindPropertyNames(moduleKindId);
    return PartialView(modulePropertyNames);
  }

modulePropertyNames可能包含List of strings，可能为null。

我想做什么

我想为传递给Partial视图的每个字符串创建文本框，其中占位符或标签为字符串，用户将在那里键入一些文本，我稍后会检索它。

我一直在做什么

我现在正在关注，但它说无法解析符号TextboxFor

@foreach (var names in Model)
{
  <div class="input-block-level">@Html.TextBoxFor(names, new {@placeholder = names})</div>
}

以下是我一直致力于

        Enabling request validation in view pages would cause validation to occur
        after the input has already been processed by the controller. By default

Answer 1

Html.TextBoxFor将Expression<Func<List<Model>>, TProperty>作为第一个参数。尝试以另一种方式使用它：

@for (int i = 0; i < Model.Count; i++)
{
    @Html.TextBoxFor(name => name[i], new {@placeholder = names})
}

或使用Html.TextBox()：

@for (int i = 0; i < Model.Count; i++)
{
    @Html.TextBox("name[" + i + "]", Model[i], new {@placeholder = names})
}

在局部视图中不能使用Html助手？
