I am using MVC to display a table of checkbox options. I know that I can call EditorFor() on a collection of objects and it will produce a list of them by looping through the collection and outputting HTML based on each item's editor template. My question is, is there a way of accessing the iterator of this loop within the editor template, so that I can start a new row of the table every, say, 3 columns?

Additionally, naming the items the correct thing for your model binding is important. See this article:

  • Excellent, thanks. I especially found helpful the part describing naming the complex object array elements. – Bondolin Oct 26 '12 at 20:51

  • thanks for the reply, but I already have a template; I'm trying to get it to work with the iterator from the automatic MVC loop started by using an EditorFor a collection. – Bondolin Oct 26 '12 at 19:48

The simplest you can use:

  List<string> items = new List<string>();
  items.Add("Item 1");
  items.Add("Item 2");
  items.Add("Item 3");

  var result = items.Select((item, index) => new { index, item });

and then if(index % 3 == 0) { ... }

OR

In ASP.NET MVC, is there a way to get the loop index when using EditorTemplates?
