Trying to use EditorFor with ICollection <string> in an ASP.NET MVC3 view?

Question

I am trying to show a class object in the Create view, where the property is ICollection<string> .

For instance...

 namespace StackOverflow.Entities { public class Question { public int Id { get; set; } .... public ICollection<string> Tags { get; set; } } } 

and if the view was like a StackOverflow "ask question" page, where the Tags html element is one input box . I'm not sure how to do this in ASP.NET MVC3 view

Any ideas?

I tried using EditorFor , but nothing was displayed in the browser because it is not sure how to display the collection of strings.

Start by decorating your model with the [UIHint] attribute:

 public class Question { public int Id { get; set; } [UIHint("tags")] public ICollection<string> Tags { get; set; } } 

and then on the main screen:

 @model StackOverflow.Entities.Question @Html.EditorFor(x => x.Tags) 

and then you can write your own editor template ( ~/Views/Shared/EditorTemplates/tags.cshtml ):

 @model ICollection<string> @Html.TextBox("", string.Join(",", Model)) 

or if you do not like decoration, you can also specify an editor template that will be used for this property directly in the view:

 @model StackOverflow.Entities.Question @Html.EditorFor(x => x.Tags, "tags")
