如何设置Html.TextBoxFor默认值？ [英] How to set a default value with Html.TextBoxFor?

问题描述

简单的问题，如果从ASP.NET MVC框架1使用HTML辅助很容易设置的默认值上一个文本框，因为有一个过载 Html.TextBox（字符串名称，对象的值）。当我尝试使用的 Html.TextBoxFor 的方法，我的第一个猜测是尝试，没有工作的情况如下：

Simple question, if you use the Html Helper from ASP.NET MVC Framework 1 it is easy to set a default value on a textbox because there is an overload Html.TextBox(string name, object value). When I tried using the Html.TextBoxFor method, my first guess was to try the following which did not work:

<%: Html.TextBoxFor(x => x.Age, new { value = "0"}) %>

我应该只是Html.TextBox（字符串对象）坚持现在？

Should I just stick with Html.TextBox(string, object) for now?

推荐答案

事实证明，如果不指定型号到控制器内的视图的方法，它不会为您创建一个对象，使用默认值

It turns out that if you don't specify the Model to the View method within your controller, it doesn't create a object for you with the default values.

[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Create()
{
  // Loads default values
  Instructor i = new Instructor();
  return View("Create", i);
}

[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Create()
{
  // Does not load default values from instructor
  return View("Create");
}
