<p>Here is what I ended up needing to do:</p> <p>Define a new Controller Method to handle the post back with the relevant Model class, and process the nested related Checkboxes with this in the View:</p> <pre><code> @Html.Raw(ViewBag.TextBoxes) </code></pre> <p>I also renamed the class for from 'RadioButtonItem' to 'TableOrViewItem' for clarity. Here's the Controller method I addeed:</p> <pre><code> [HttpPost] public ActionResult Connect( TableOrViewItem rbl ) { /* TEST SESSION FIRST*/ if ( Session["connstr"] == null ) return RedirectToAction( "Index" ); else { ViewBag.Message = ""; ViewBag.ConnectionString = Server.UrlDecode( Session["connstr"].ToString() ); ViewBag.Server = ParseConnectionString( ViewBag.ConnectionString, "Data Source" ); ViewBag.Database = ParseConnectionString( ViewBag.ConnectionString, "Initial Catalog" ); ViewBag.Selected = Request["name"] != null ? Request["name"].ToString() : ""; ViewBag.ObjectID = Request["id"] != null ? Request["id"].ToString() : ""; using ( var dbo = new SqlObjectContext( ViewBag.ConnectionString ) ) { // obtain this item's objectid string CurrentObjectId = Request["id"].ToString(); int CurrentID = StringToInt( CurrentObjectId ); // populate Checkbox Area var rawColumns = dbo.Set<SqlColumn>() .Where( column => column.ObjectId == CurrentID ) .OrderBy( o => o.ColumnId ) .ToList(); string htmlColumns = string.Empty; foreach ( EF_Utility.Models.SqlColumn item in rawColumns ) { htmlColumns += "<input checked=\"checked\" id=\"RadioButtonViewModel_CheckBox" + item.ColumnId + "\" name=\"CheckBox_" + item.ColumnId + "\" type=\"checkbox\" value=\"" + item.Name + "\">" + item.Name + " <br>"; } if(! string.IsNullOrEmpty(htmlColumns)) { htmlColumns += "<br /><center><input type=\"submit\" value=\"Generate\" name=\"btnGenerate\" id=\"btnGenerate\" /></center>"; htmlColumns += "<input type=\"hidden\" name=\"id\" value=\"" + CurrentObjectId + "\" />"; htmlColumns += "<input type=\"hidden\" name=\"name\" value=\"" + ViewBag.Selected + "\" />"; } ViewBag.TextBoxes = htmlColumns; /*var ColumnItemList = columns .Select( c => new ColumnItem { Name = c.Name, Selected = true, ObjectId = c.ObjectId } ) .Where( tvi => tvi.ObjectId == CurrentID ); */ // Check to see if the user wants the list generated if(Request["btnGenerate"] != null) { string sNewLine = System.Environment.NewLine; string htmlText = "[Table( \"" + ViewBag.Selected +"\" )]" + sNewLine + "public class " + POCOFormated( ViewBag.Selected ) + sNewLine + "{"; string tempColumn = string.Empty; string tempName = string.Empty; foreach(string key in Request.Form) { if(!key.StartsWith("CheckBox_")) continue; tempName = POCOFormated( Request.Form[key] ); htmlText = htmlText + sNewLine + "\t" + "public " + "...fieldtype..." + " " + tempName.Trim() + " { get; set; }" + sNewLine; } htmlText = htmlText + sNewLine + "}"; ViewBag.TextArea = htmlText; } var objects = dbo.Set<SqlObject>().ToArray(); var model = objects .Select( o => new TableOrViewItem { Name = o.Name, Selected = false, ObjectId = o.ObjectId } ) .OrderBy( rb => rb.Name ); return View( model ); } } } </code></pre>

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.
