No need to create custom template for MVC 4. Use TextBox instead of EditFor here special html attributes are not supported, it is only supported from MVC 5. TextBox is should support for MVC 4, I don't know about other version.

@Html.TextBox("test", "", new { @id = "signupform", @class = "form-control", @role = "form",@placeholder="Name" })

I had the same frustrating issue  and I didn t want to create an EditorTemplate that applied to all DateTime values  there were times in my UI where I wanted to display the time and not a jQuery UI drop-down calendar   In my research  the root issues I came across were    The standard TextBoxFor helper allowed me to apply a custom class of  date-picker  to render the unobtrusive jQuery UI calender  but TextBoxFor wouldn t format a DateTime without the time  therefore causing the calendar rendering to fail  The standard EditorFor would display the DateTime as a formatted string  when decorated with the proper attributes such as  DisplayFormat ApplyFormatInEditMode   true  DataFormatString     0 dd MM yyyy      but it wouldn t allow me to apply the custom  date-picker  class    Therefore  I created custom HtmlHelper class that has the following benefits    The method automatically converts the DateTime into the ShortDateString needed by the jQuery calendar  jQuery will fail if the time is present   By default  the helper will apply the required htmlAttributes to display a jQuery calendar  but they can be overridden if needs be  If the date is null  ASP NET MVC will put a date of 1 1 0001 as a value     This method replaces that with an empty string   public static MvcHtmlString CalenderTextBoxFor lt TModel  TProperty gt  this HtmlHelper lt TModel gt  htmlHelper  Expression lt Func lt TModel  TProperty gt  gt  expression  object htmlAttributes   null        var mvcHtmlString   System Web Mvc Html InputExtensions TextBoxFor htmlHelper  expression  htmlAttributes    new    class    text-box single-line date-picker          var xDoc   XDocument Parse mvcHtmlString ToHtmlString         var xElement   xDoc Element  input        if  xElement    null                var valueAttribute   xElement Attribute  value            if  valueAttribute    null                        valueAttribute Value   DateTime Parse valueAttribute Value  ToShortDateString                if  valueAttribute Value     1 1 0001                   valueAttribute Value   string Empty                      return new MvcHtmlString xDoc ToString         And for those that want to know the JQuery syntax that looks for objects with the date-picker class decoration to then render the calendar  here it is     document  ready function              date-picker   datepicker   inline  true  maxDate  0  changeMonth  true  changeYear  true             date-picker   datepicker  option    showAnim    slideDown

I used another solution using CSS attribute selectors to get what you need   Indicate the HTML attribute you know and put in the relative style you want   Like below   input type  date          width  150px

Html EditorFor m  gt m Created         does not allow any arguments to be passed in for the Text box  This is how you can apply attributes    Html TextBoxFor m  gt m Created  new    class   date   Name   myName   id  myId

It is possible to provide a class or other information through AdditionalViewData - I use this where I m allowing a user to create a form based on database fields  propertyName  editorType  and editorClass    Based on your initial example    Html EditorFor x   gt  x Created  new   cssClass    date       and in the custom template    lt div gt       Html TextBoxFor x   gt  x Created  new    class   ViewData  cssClass       lt  div gt

You can create the same behavior creating a simple custom editor called DateTime cshtml  saving it in Views Shared EditorTemplates   model DateTime         var css   ViewData  class               Html TextBox      Model    DateTime MinValue  Model ToString  dd MM yyyy     string Empty   new    class    calendar medium     css        and in your views    Html EditorFor model   gt  model StartDate  new    class    required       Note that in my example I m hard-coding two css classes and the date format  You can  of course  change that  You also can do the same with others html attributes  like readonly  disabled  etc

You can t set class for the generic EditorFor  If you know the editor that you want  you can use it straight away  there you can set the class  You don t need to build any custom templates    Html TextBoxFor x   gt  x Created  new    class    date

User · Answer

There isn t any EditorFor override that lets you pass in an anonymous object whose properties would somehow get added as attributes on some tag  especially for the built-in editor templates  You would need to write your own custom editor template and pass the value you want as additional viewdata

As of ASP NET MVC 5 1  adding a class to an EditorFor is possible  the original question specified ASP NET MVC 3  and the accepted answer is still the best with that considered     Html EditorFor x  gt  x MyProperty      new   htmlAttributes   new    class    MyCssClass         See  What s New in ASP NET MVC 5 1  Bootstrap support for editor templates

You can use    Html EditorFor x   gt  x Created  new   htmlAttributes   new    class    date          At least with ASP NET MVC 5  but I do not know how that was with ASP NET MVC 3

While the question was targeted at MVC 3 0  we find the problem persists in MVC 4 0 as well   MVC 5 0 now includes natively an overload for htmlAttributes   I am forced to use MVC 4 0 at my current place of employment and needed to add a css class for JQuery integration   I solved this problem using a single extension method     Extension Method   using System Linq  using System Web Mvc  using System Web Routing  using System Xml Linq   namespace MyTest Utilities       public static class MVCHelperExtensionMethods               public static MvcHtmlString AddHtmlAttributes this MvcHtmlString input  object htmlAttributes                           WE WANT TO INJECT INTO AN EXISTING ELEMENT   IF THE ATTRIBUTE ALREADY EXISTS  ADD TO IT  OTHERWISE                CREATE THE ATTRIBUTE WITH DATA VALUES                  USE XML PARSER TO PARSE HTML ELEMENT             var xdoc   XDocument Parse input ToHtmlString                 var rootElement    from e in xdoc Elements   select e  FirstOrDefault                    IF WE CANNOT PARSE THE INPUT USING XDocument THEN RETURN THE ORIGINAL UNMODIFIED              if  rootElement    null                                return input                                USE RouteValueDictionary TO PARSE THE NEW HTML ATTRIBUTES             var routeValueDictionary   new RouteValueDictionary htmlAttributes                foreach  var routeValue in routeValueDictionary                                var attribute   rootElement Attribute routeValue Key                    if  attribute    null                                        attribute   new XAttribute name  routeValue Key  value  routeValue Value                       rootElement Add attribute                                     else                                       attribute Value   string Format   0   1    attribute Value  routeValue Value  Trim                                                 var elementString   rootElement ToString                var response   new MvcHtmlString elementString               return response                      HTML Markup Usage    Html EditorFor expression  x   gt  x MyTestProperty  AddHtmlAttributes new    class    form-control        Make sure to include the extension method s namespace in the razor view   Explanation  The idea is to inject into the existing HTML   I opted to parse the current element using Linq-to-XML using XDocument Parse     I pass the htmlAttributes as type object   I utilize MVC RouteValueDictionary to parse the htmlAttributes passed in   I merge the attributes where they already exist  or add a new attribute if it does not yet exist   In the event the input is not parsable by XDocument Parse   I abandon all hope and return the original input string   Now I can use the benefit of the DisplayFor  rendering datatypes such as currency appropriately  but also have the ability to specify css classes  and any other attribute for that matter    Could be helpful for adding attributes such as data-   or ng-   Angular

I just needed to set the size of one textbox on one page  Coding attributes on the model and creating custom editor templates were overkill  so I just wrapped the  Html EditorFor call with a span tag that called a class which specifies the size of the textbox   CSS class declaration    SpaceAvailableSearch input       width 25px      View code    lt span class  SpaceAvailableSearch  gt  Html EditorFor model   gt  model SearchForm SpaceAvailable  lt  span gt

User · Answer

Adding a class to Html EditorFor doesn t make sense as inside its template you could have many different tags  So you need to assign the class inside the editor template    Html EditorFor x   gt  x Created    and in the custom template    lt div gt       Html TextBoxForModel x   gt  x Created  new    class    date      lt  div gt
