Here's what I've found:

<pre><code>@Html.TextBoxFor(c =&gt; c.Propertyname, new { @Value = "5" })
</code></pre>

works with a capital V, not a lower case v (the assumption being value is a keyword used in setters typically) <a href="https://stackoverflow.com/questions/3034986/how-to-set-a-default-value-with-html-textboxfor">Lower vs upper value</a>

<pre><code>@Html.EditorFor(c =&gt; c.Propertyname, new { @Value = "5" })
</code></pre>

does not work 

Your code ends up looking like this though

<pre><code>&lt;input Value="5" id="Propertyname" name="Propertyname" type="text" value="" /&gt;
</code></pre>

Value vs. value. Not sure I'd be too fond of that. 

Why not just check in the controller action if the proprety has a value or not and if it doesn't just set it there in your view model to your defaulted value and let it bind so as to avoid all this monkey work in the view?

blocks|key|3179021|text|更好的选择是在视图模型中执行此操作，如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3179022|public+class+MyVM

}|code-block|syntax|javascript|3179023|那么在你看来|3179024|@Html.EditorFor(c+=>+c.PropertyName)|3179025|将按照您想要的方式工作(如果没有值，则会有默认值)|3179026|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Better option is to do this in your view model like

<pre><code>public class MyVM
{
 int _propertyValue = 5;//set Default Value here
 public int PropertyName{
 get
 {
 return _propertyValue; 
 }
 set
 {
 _propertyValue = value;
 }
 }
}
</code></pre>

Then in your view 

<pre><code>@Html.EditorFor(c =&gt; c.PropertyName)
</code></pre>

will work the way u want it (if no value default value will be there)

blocks|key|2965326|text|在视图中设置默认值是不正确的。视图应该执行显示工作，而不是更多。这一行为打破了MVC模式的思想。所以设置控制器类的默认创建方法的位置是正确的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2965327|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Its not right to set default value in View. The View should perform display work, not more. This action breaks ideology of MVC pattern. So the right place to set defaults - create method of controller class.

blocks|key|2965355|text|最简单的方法是通过控制器传递创建的实体的一个新实例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2965356|//GET
public+ActionResult+CreateNewMyEntity(string+default_value)
{
++++MyEntity+newMyEntity+=+new+MyEntity();
++++newMyEntity._propertyValue+=+default_value;

++++return+View(newMyEntity);
}|code-block|syntax|javascript|2965357|如果要通过ActionLink传递缺省值|2965358|@Html.ActionLink("Create+New",+"CreateNewMyEntity",+new+{+default_value+=+"5"+})|2965359|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

The clean way to do so is to pass a new instance of the created entity through the controller:

<pre><code>//GET
public ActionResult CreateNewMyEntity(string default_value)
{
 MyEntity newMyEntity = new MyEntity();
 newMyEntity._propertyValue = default_value;

 return View(newMyEntity);
}
</code></pre>

If you want to pass the default value through ActionLink

<pre><code>@Html.ActionLink("Create New", "CreateNewMyEntity", new { default_value = "5" })
</code></pre>

I just did this (Shadi's first answer) and it works a treat:

<pre><code> public ActionResult Create()
 {
 Article article = new Article();
 article.Active = true;
 article.DatePublished = DateTime.Now;
 ViewData.Model = article;
 return View();
 } 
</code></pre>

I could put the default values in my model like a propper MVC addict: (I'm using Entity Framework)

<pre><code> public partial class Article
 {
 public Article()
 {
 Active = true;
 DatePublished = Datetime.Now;
 }
 }

 public ActionResult Create()
 {
 Article article = new Article();
 ViewData.Model = article;
 return View();
 } 
</code></pre>

Can anyone see any downsides to this?

In the constructor method of your model class set the default value whatever you want.
Then in your first action create an instance of the model and pass it to your view.

 VolunteerModel model = new VolunteerModel(); //to set the default values
 return View(model);

Would the following work?? Where the number 5 is a parameter I pass into the text field to set default value.
