    <p>I've solved my question. But It may be not the best answer : I created an object to return from controller :</p> <pre><code>public class GroupViewDetail { public tbl_group GroupDB { get; set; } public List&lt;GroupViewRow&gt; GVRow { get; set; } public List&lt;tbl_action&gt; ListActionDB { get; set; } public class GroupViewRow { public tbl_controller ControllerDB { get; set; } public List&lt;SubGroupViewRow&gt; SubGVRow { get; set; } public class SubGroupViewRow { public tbl_action ActionDB { get; set; } public bool IsVisible { get; set; } public bool IsExisted { get; set; } } } } </code></pre> <p>Then, in controller, I do this :</p> <pre><code>DBDataContext db = new DBDataContext(); GroupViewDetail gvd = new GroupViewDetail(); gvd.GroupDB = db.tbl_groups.Single&lt;tbl_group&gt;(g =&gt; g.id == id); gvd.ListActionDB = (from a in db.tbl_actions select a).DefaultIfEmpty&lt;tbl_action&gt;().ToList&lt;tbl_action&gt;(); gvd.GVRow = new List&lt;GroupViewDetail.GroupViewRow&gt;(); foreach (tbl_controller c in db.tbl_controllers) { GroupViewDetail.GroupViewRow gvr = new GroupViewDetail.GroupViewRow(); gvr.ControllerDB = c; gvr.SubGVRow = new List&lt;GroupViewDetail.GroupViewRow.SubGroupViewRow&gt;(); foreach (tbl_action a in db.tbl_actions) { GroupViewDetail.GroupViewRow.SubGroupViewRow sgvr = new GroupViewDetail.GroupViewRow.SubGroupViewRow(); sgvr.ActionDB = a; sgvr.IsExisted = (from t in db.tbl_group_controller_actions where t.groupId == id &amp;&amp; t.controllerId == c.id &amp;&amp; t.actionId == a.id select t).DefaultIfEmpty&lt;tbl_group_controller_action&gt;().Single&lt;tbl_group_controller_action&gt;() == null ? false : true; sgvr.IsVisible = (from z in db.tbl_controller_actions where z.actionId == a.id &amp;&amp; z.controllerId == c.id select z).DefaultIfEmpty&lt;tbl_controller_action&gt;().Single&lt;tbl_controller_action&gt;() == null ? false : true; gvr.SubGVRow.Add(sgvr); } gvd.GVRow.Add(gvr); } return View(gvd); </code></pre> <p>finally, this is the view :</p> <pre><code>&lt;%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/MasterPage.Master" Inherits="System.Web.Mvc.ViewPage&lt;TestMVC4.Models.Group.GroupViewDetail&gt;" %&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
