在剃刀语法文本框的默认值 [英] Text box default value in Razor syntax

问题描述

    <div class="editor-label">
        @Html.LabelFor(model => model.UserName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.AccountModel.UserName)
        @Html.ValidationMessageFor(model => model.AccountModel.UserName)

推荐答案

在你的控制器动作，你可以填充视图模型，并在其上​​设置相应的属性。因此，假如你的看法是强类型为 MyViewModel ：

In your controller action you could populate the view model and set the corresponding properties on it. So assuming your view is strongly typed to MyViewModel:

[Authorize]
public ActionResult Foo()
{
    var model = new MyViewModel
    {
        UserName = User.Identity.Name
    };
    return View(model);
}

和在视图中简单：

<div class="editor-label">
    @Html.LabelFor(model => model.UserName)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.UserName)
    @Html.ValidationMessageFor(model => model.UserName)
</div>

如果您的视图模型具有一定的 AccountModel 属性，你必须实例化，并在控制器动作来填充它。在我的例子我已经夷为平地视图模型。

If your view model has some AccountModel property, you will have to instantiate and populate it in the controller action. In my example I have flattened the view model.
