I wrote a blog entry to answer my own question

<a href="http://aspadvice.com/blogs/kiran/archive/2009/11/29/Adding-html-attributes-support-for-Templates-_2D00_-ASP.Net-MVC-2.0-Beta_2D00_1.aspx" rel="nofollow">Adding html attributes support for Templates - ASP.Net MVC 2.0 Beta</a>

blocks|key|438847|text|在MVC3中，您可以按如下方式设置宽度：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|438848|@Html.TextBoxFor(c+=>+c.PropertyName,+new+{+style+=+"width:+500px;"+})|code-block|syntax|javascript|438849|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In MVC3, you can set width as follows:

<pre><code>@Html.TextBoxFor(c =&gt; c.PropertyName, new { style = "width: 500px;" })
</code></pre>

I solved this by creating an EditorTemplate named String.ascx in my /Views/Shared/EditorTemplates folder:

<pre><code>&lt;%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl&lt;string&gt;" %&gt;
&lt;% int size = 10;
 int maxLength = 100;
 if (ViewData["size"] != null)
 {
 size = (int)ViewData["size"];
 }
 if (ViewData["maxLength"] != null)
 {
 maxLength = (int)ViewData["maxLength"];
 }
%&gt;
&lt;%= Html.TextBox("", Model, new { Size=size, MaxLength=maxLength }) %&gt;
</code></pre>

In my view, I use

<pre><code>&lt;%= Html.EditorFor(model =&gt; model.SomeStringToBeEdited, new { size = 15, maxLength = 10 }) %&gt;
</code></pre>

Works like a charm for me!

None of the answers in this or any other thread on setting HTML attributes for @Html.EditorFor were much help to me. However, I did find a great answer at 

<a href="http://forums.asp.net/t/1687150.aspx/1" rel="noreferrer">Styling an @Html.EditorFor helper</a>

I used the same approach and it worked beautifully without writing a lot of extra code. Note that the id attribute of the html output of Html.EditorFor is set. The view code

<pre><code>&lt;style type="text/css"&gt;
#dob
{
 width:6em;
}
&lt;/style&gt;

@using (Html.BeginForm())
{
 Enter date: 
 @Html.EditorFor(m =&gt; m.DateOfBirth, null, "dob", null)
}
</code></pre>

The model property with data annotation and date formatting as "dd MMM yyyy"

<pre><code>[Required(ErrorMessage= "Date of birth is required")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd MMM yyyy}")]
public DateTime DateOfBirth { get; set; }
</code></pre>

Worked like a charm without writing a whole lot of extra code. This answer uses ASP.NET MVC 3 Razor C#.

blocks|key|1752316|text|可能想看看Kiran+Chand's+Blog+post，他在视图模型上使用定制的元数据，例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1752317|[HtmlProperties(Size+=+5,+MaxLength+=+10)]
public+string+Title+{+get;+set;+}|code-block|syntax|javascript|1752318|这与利用元数据的自定义模板相结合。在我看来，这是一种干净而简单的方法，但我希望看到这种常见的用例被内置到mvc中。|1752319|entityMap|0|LINK|mutability|MUTABLE|url|http://aspadvice.com/blogs/kiran/archive/2009/11/29/Adding-html-attributes-support-for-Templates-_2D00_-ASP.Net-MVC-2.0-Beta_2D00_1.aspx^0|5|N|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@$A|T|B|U|1|V]]|C|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|X|8|@]|9|@]|C|$]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|C|$]]]|L|$M|$5|N|O|P|C|$Q|R]]]]

May want to look at <a href="http://aspadvice.com/blogs/kiran/archive/2009/11/29/Adding-html-attributes-support-for-Templates-_2D00_-ASP.Net-MVC-2.0-Beta_2D00_1.aspx" rel="noreferrer">Kiran Chand's Blog post</a>, he uses custom metadata on the view model such as:

<pre><code>[HtmlProperties(Size = 5, MaxLength = 10)]
public string Title { get; set; }
</code></pre>

This is combined with custom templates that make use of the metadata. A clean and simple approach in my opinion but I would like to see this common use case built-in to mvc.

I'm surprised no one mentioned passing it in "additionalViewData" and reading it on the other side.

 {
 htmlAttributes = new

Editor template:

&lt;%= Html.TextBox("", Model, ViewData["htmlAttributes"])) %&gt;

The problem is, your template can contain several HTML elements, so MVC won't know to which one to apply your size/class. You'll have to define it yourself.

Make your template derive from your own class called TextBoxViewModel:

<pre><code>public class TextBoxViewModel
{
 public string Value { get; set; }
 IDictionary&lt;string, object&gt; moreAttributes;
 public TextBoxViewModel(string value, IDictionary&lt;string, object&gt; moreAttributes)
 {
 // set class properties here
 }
 public string GetAttributesString()
 {
 return string.Join(" ", moreAttributes.Select(x =&gt; x.Key + "='" + x.Value + "'").ToArray()); // don't forget to encode
 }
</code></pre>

}

In the template you can do this:

<pre><code>&lt;input value="&lt;%= Model.Value %&gt;" &lt;%= Model.GetAttributesString() %&gt; /&gt;
</code></pre>

In your view you do:

<pre><code>&lt;%= Html.EditorFor(x =&gt; x.StringValue) %&gt;
or
&lt;%= Html.EditorFor(x =&gt; new TextBoxViewModel(x.StringValue, new IDictionary&lt;string, object&gt; { {'class', 'myclass'}, {'size', 15}}) %&gt;
</code></pre>

The first form will render default template for string. The second form will render the custom template.

Alternative syntax use fluent interface:

<pre><code>public class TextBoxViewModel
{
 public string Value { get; set; }
 IDictionary&lt;string, object&gt; moreAttributes;
 public TextBoxViewModel(string value, IDictionary&lt;string, object&gt; moreAttributes)
 {
 // set class properties here
 moreAttributes = new Dictionary&lt;string, object&gt;();
 }

 public TextBoxViewModel Attr(string name, object value)
 {
 moreAttributes[name] = value;
 return this;
 }
</code></pre>

}

<pre><code> // and in the view
 &lt;%= Html.EditorFor(x =&gt; new TextBoxViewModel(x.StringValue).Attr("class", "myclass").Attr("size", 15) %&gt;
</code></pre>

Notice that instead of doing this in the view, you may also do this in controller, or much better in the ViewModel:

<pre><code>public ActionResult Action()
{
 // now you can Html.EditorFor(x =&gt; x.StringValue) and it will pick attributes
 return View(new { StringValue = new TextBoxViewModel(x.StringValue).Attr("class", "myclass").Attr("size", 15) });
}
</code></pre>

Also notice that you can make base TemplateViewModel class - a common ground for all your view templates - which will contain basic support for attributes/etc.

But in general I think MVC v2 needs a better solution. It's still Beta - go ask for it ;-)

I think using CSS is the way to go. I wish I could do more with .NET coding, like in XAML, but in the browser CSS is king.

Site.css 

<pre><code>#account-note-input { 
 width:1000px; 
 height:100px; 
} 
</code></pre>

.cshtml

<pre><code>&lt;div class="editor-label"&gt;

&lt;/div&gt; 
&lt;div class="editor-field"&gt; 
 @Html.EditorFor(model =&gt; model.Note, null, "account-note-input", null) 
 @Html.ValidationMessageFor(model =&gt; model.Note)

blocks|key|1752909|text|与在MVC5中一样，如果您希望添加任何属性，可以简单地执行以下操作|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1752910|+@Html.EditorFor(m+=>+m.Name,+new+{+htmlAttributes+=+new+{+@required+=+"true",+@anotherAttribute+=+"whatever"+}+})|code-block|syntax|javascript|1752911|从this+blog找到的信息|offset|length|1752912|entityMap|0|LINK|mutability|MUTABLE|url|http://cpratt.co/html-editorfor-and-htmlattributes/^0|0|0|1|9|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@$I|V|J|W|1|X]]|A|$]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|L|$M|$5|N|O|P|A|$Q|R]]]]

You can define attributes for your properties.

<pre><code>[StringLength(100)]
public string Body { get; set; }
</code></pre>

This is known as <code>System.ComponentModel.DataAnnotations</code>.
If you can't find the <code>ValidationAttribute</code> that you need you can allways define custom attributes.

This may not be the slickest solution, but it is straightforward. You can write an extension to the HtmlHelper.EditorFor class. In that extension, you can supply an options parameter that will write the options to the ViewData for the helper. Here's some code:

First, the extension method:

<pre><code>public static MvcHtmlString EditorFor&lt;TModel, TProperty&gt;(this HtmlHelper&lt;TModel&gt; helper, Expression&lt;Func&lt;TModel, TProperty&gt;&gt; expression, TemplateOptions options)
{
 return helper.EditorFor(expression, options.TemplateName, new
 {
 cssClass = options.CssClass
 });
}
</code></pre>

Next, the options object:

<pre><code>public class TemplateOptions
{
 public string TemplateName { get; set; }
 public string CssClass { get; set; }
 // other properties for info you'd like to pass to your templates,
 // and by using an options object, you avoid method overload bloat.
}
</code></pre>

And finally, here's the line from the String.ascx template:

<pre><code>&lt;%= Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, new { @class = ViewData["cssClass"] ?? "" }) %&gt;
</code></pre>

Frankly, I think this is straightforward and clear to the poor soul who has to maintain your code down the road. And it is easy to extend for various other bits of info you'd like to pass to your templates. It's working well so far for me in a project where I'm trying to wrap as much as I can in a set of template to help standardize the surrounding html, a la <a href="http://bradwilson.typepad.com/blog/2009/10/aspnet-mvc-2-templates-part-5-master-page-templates.html" rel="nofollow noreferrer">http://bradwilson.typepad.com/blog/2009/10/aspnet-mvc-2-templates-part-5-master-page-templates.html</a>.

blocks|key|438909|text|在我的实践中，我发现最好使用只有一个HtmlHelper的EditorTemplates+-+TextBox，即在大多数情况下。如果我想要一个用于更复杂html结构的模板，我将编写一个单独的HtmlHelper。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|438910|假设我们可以将整个ViewData对象放在TextBox的htmlAttributes的位置。此外，如果ViewData的一些属性需要特殊处理，我们可以为它们编写一些自定义代码：|438911|@model+DateTime?|code-block|syntax|javascript|438912|@*

In my practice I found that it is best to use EditorTemplates with only one HtmlHelper in it - TextBox that is in most cases. If I want a template for more complex html structure, I'll write a separate HtmlHelper.

Given that we can stick the whole ViewData object in place of htmlAttributes of the TextBox. In addition we can write some customization code for some of the properties of the ViewData if they need special treatment:

<pre class="lang-cs prettyprint-override"><code>@model DateTime?
</code></pre>

<pre class="lang-none prettyprint-override"><code>@*
 1) applies class datepicker to the input;
 2) applies additionalViewData object to the attributes of the input
 3) applies property "format" to the format of the input date.
*@
</code></pre>

<pre class="lang-cs prettyprint-override"><code>@{
 if (ViewData["class"] != null) { ViewData["class"] += " datepicker"; }
 else { ViewData["class"] = " datepicker"; }
 string format = "MM/dd/yyyy";
 if (ViewData["format"] != null)
 {
 format = ViewData["format"].ToString();
 ViewData.Remove("format");
 }
}

@Html.TextBox("", (Model.HasValue ? Model.Value.ToString(format) : string.Empty), ViewData)
</code></pre>

Below are the examples of the syntax in the view and the outputted html:

<pre class="lang-cs prettyprint-override"><code>@Html.EditorFor(m =&gt; m.Date)
</code></pre>

<pre><code>&lt;input class="datepicker" data-val="true" data-val-required="&amp;amp;#39;Date&amp;amp;#39; must not be empty." id="Date" name="Date" type="text" value="01/08/2012"&gt;
</code></pre>

<pre class="lang-cs prettyprint-override"><code>@Html.EditorFor(m =&gt; m.Date, new { @class = "myClass", @format = "M/dd" })
</code></pre>

<pre><code>&lt;input class="myClass datepicker" data-val="true" data-val-required="&amp;amp;#39;Date&amp;amp;#39; must not be empty." id="Date" name="Date" type="text" value="1/08"&gt;
</code></pre>

blocks|key|1752733|text|因为问题是针对EditorFor，而不是TextBoxFor，所以WEFX的建议行不通。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1752734|对于更改单个输入框，您可以处理EditorFor方法的输出：|1752735|<%25:+new+HtmlString(Html.EditorFor(m=>m.propertyname).ToString().Replace("class=\"text-box+single-line\"",+"class=\"text-box+single-line+my500pxWideClass\""))+%25>|code-block|syntax|javascript|1752736|还可以更改所有的EditorFors，因为MVC使用.text-box设置了EditorFor文本框的类，因此您可以直接在样式表或页面上覆盖此样式。|1752737|.text-box+{

Because the question is for EditorFor not TextBoxFor WEFX's suggestion doesn't work. 

For changing individual input boxes, you can process the output of the EditorFor method:

<pre><code>&lt;%: new HtmlString(Html.EditorFor(m=&gt;m.propertyname).ToString().Replace("class=\"text-box single-line\"", "class=\"text-box single-line my500pxWideClass\"")) %&gt;
</code></pre>

It is also possible to change ALL your EditorFors as it turns out MVC sets the class of EditorFor text boxes with .text-box, therefore you can just override this style, in your stylesheet or on the page. 

<pre><code>.text-box {
 width: 80em;
}
</code></pre>

Additionally, you could set the style for

<pre><code>input[type="text"] {
 width: 200px;
}
</code></pre>

<ul>
<li>this overrides .text-box and will change all input text boxes, EditorFor or otherwise. </li>
</ul>

blocks|key|345871|text|解决这个问题的一种方法是在视图模型上使用委托来处理打印输出的特殊渲染，如下所示。我已经为一个分页类这样做了，我在模型Func<int,+string>+RenderUrl上公开了一个公共属性来处理它。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|345872|因此，定义如何写入自定义位：|345873|Model.Paging.RenderUrl+=+(page)+=>+{+return+string.Concat(@"/foo/",+page);+};|code-block|syntax|javascript|345874|输出Paging类的视图：|345875|@Html.DisplayFor(m+=>+m.Paging)|345876|实际Paging视图的...and：|345877|@model+Paging

++++</ul>
}|345878|这可能被视为过于复杂的问题，但我在任何地方都使用这些寻呼机，无法忍受看到相同的样板代码来呈现它们。|345879|entityMap^0|1M|R|0|0|0|2|6|0|0|2|6|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|11|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|12|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|13|8|@$9|14|A|15|B|C]]|D|@]|E|$]]|$1|O|3|P|5|J|7|16|8|@]|D|@]|E|$K|L]]|$1|Q|3|R|5|6|7|17|8|@$9|18|A|19|B|C]]|D|@]|E|$]]|$1|S|3|T|5|J|7|1A|8|@]|D|@]|E|$K|L]]|$1|U|3|V|5|6|7|1B|8|@]|D|@]|E|$]]|$1|W|3|-4|5|6|7|1C|8|@]|D|@]|E|$]]]|X|$]]

One way you could get round it is by having delegates on the view model to handle printing out special rendering like this. I've done this for a paging class, I expose a public property on the model <code>Func&lt;int, string&gt; RenderUrl</code> to deal with it.

So define how the custom bit will be written:

<pre><code>Model.Paging.RenderUrl = (page) =&gt; { return string.Concat(@"/foo/", page); };
</code></pre>

Output the view for the <code>Paging</code> class:

<pre><code>@Html.DisplayFor(m =&gt; m.Paging)
</code></pre>

...and for the actual <code>Paging</code> view:

<pre><code>@model Paging
@if (Model.Pages &gt; 1)
{
 &lt;ul class="paging"&gt;
 @for (int page = 1; page &lt;= Model.Pages; page++)
 {
 &lt;li&gt;&lt;a href="@Model.RenderUrl(page)"&gt;@page&lt;/a&gt;&lt;/li&gt;
 }
 &lt;/ul&gt;
}
</code></pre>

It could be seen as over-complicating matters but I use these pagers everywhere and couldn't stand seeing the same boilerplate code to get them rendered.

UPDATE: hm, obviously this won't work because model is passed by value so attributes are not preserved; but I leave this answer as an idea.

Another solution, I think, would be to add your own TextBox/etc helpers, that will check for your own attributes on model.

<pre><code>public class ViewModel
{
 [MyAddAttribute("class", "myclass")]
 public string StringValue { get; set; }
}

public class MyExtensions
{
 public static IDictionary&lt;string, object&gt; GetMyAttributes(object model)
 {
 // kind of prototype code...
 return model.GetType().GetCustomAttributes(typeof(MyAddAttribute)).OfType&lt;MyAddAttribute&gt;().ToDictionary(
 x =&gt; x.Name, x =&gt; x.Value);
 }
}

&lt;!-- in the template --&gt;
&lt;%= Html.TextBox("Name", Model, MyExtensions.GetMyAttributes(Model)) %&gt;
</code></pre>

This one is easier but not as convinient/flexible.

I really liked @tjeerdans answer which utilizes the EditorTemplate named String.ascx in the /Views/Shared/EditorTemplates folder. It seems to be the most straight-forward answer to this question. However, I wanted a template using Razor syntax. In addition, it seems that MVC3 uses the String template as a default (see the StackOverflow question "<a href="https://stackoverflow.com/questions/5038858/asp-net-mvc-display-template-for-strings-is-used-for-integers" title="mvc display template for strings is used for integers">mvc display template for strings is used for integers</a>") so you need to set the model to object rather than string. My template seems to be working so far:

<pre><code>@model object 

@{ int size = 10; int maxLength = 100; }

@if (ViewData["size"] != null) {
 Int32.TryParse((string)ViewData["size"], out size); 
} 

@if (ViewData["maxLength"] != null) {
 Int32.TryParse((string)ViewData["maxLength"], out maxLength); 
}

@Html.TextBox("", Model, new { Size = size, MaxLength = maxLength})

I solved it!! 
For Razor the syntax is: 
<code>@Html.TextAreaFor(m=&gt;m.Address, new { style="Width:174px" })</code> this adjusts the text area width to the width that i defined in the style parameter.
 
For ASPx the syntax is: 
<code>&lt;%=Html.TextAreaFor(m =&gt; m.Description, new { cols = "20", rows = "15", style="Width:174px" })%&gt;</code> 
this will do the trick

Asp.Net MVC 2.0 preview builds provide helpers like 

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

If the property name is string, the above code renders a texbox.

What if I want to pass in MaxLength and Size properties to the text box or my own css class property?

Do I need to create one template for each size and length combinations in my application? If so, that doesn't make the default templates that usable.
