I've managed to figure something out. Although my problem is not exactly the same you have, but it can certainly help you. But first things first. The problem I have a number of controls (in my case they are Partial Views). For example: <pre><code>Views/Shared/EditName.cshtml Views/Shared/EditAddress.cshtml Views/Shared/EditEmail.cshtml Views/Shared/EditFavoriteColour.cshtml </code></pre> I want to define groups of these controls (in database or web.config), for example: <pre><code>SimpleEditGroup: EditName ExtendedEditGroup: EditName EditEmail FullEditGroup: EditName EditAddress EditEmail EditFavoriteColour </code></pre> Then I want to render a view based on a particular group. I was thinking the following syntax would be sufficient. <pre><code>@Html.Partial("ControlGroup:ExtendedEditGroup", Model) </code></pre> Draft of the solution I wanted to create my own render engine which will do the following: <ol> <li>If the name of the view begins with "ControlGroup:" then use previously defined groups to render the page. Each of the controls should be rendered by RazorViewEngine.</li> <li>If the name of the view doesn't begin with "ControlGroup:" just let the RazorViewEngine do its work.</li> </ol> Research I've found following resources: <ol> <li>Article on CodeProject - <a href="http://www.codeproject.com/Articles/259365/Custom-ViewEngine-in-ASP-NET-MVC3" rel="nofollow">Custom ViewEngine in ASP.NET MVC3</a></li> <li>Article based on StackOverflow question - <a href="http://www.paulstovell.com/widgets" rel="nofollow">Creating a Widget system in ASP.NET MVC 3</a></li> <li>I recommend you the book <a href="http://rads.stackoverflow.com/amzn/click/1430234040" rel="nofollow">Pro ASP.NET MVC 3 Framework</a>. It will give you the idea how many things you can customize in ASP.NET MVC 3</li> <li>Of course source code of <a href="http://aspnet.codeplex.com/releases/view/58781" rel="nofollow">ASP.NET MVC 3 RTM</a> was very helpful.</li> </ol> Final solution MyViewEngine: <pre><code>public class MyViewEngine : RazorViewEngine { IDictionary<string, List<string>> groups = new Dictionary<string, List<string>>(); public MyViewEngine() { // Temporary data source groups["SimpleEditGroup"] = new List<string>() { "EditName"}; groups["ExtendedEditGroup"] = new List<string>() { "EditName", "EditEmail"}; } public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache) { if (viewName.StartsWith("ControlGroup")) { var groupName = viewName.Split(':')[1]; var controls = new List<ViewEngineResult>(); foreach (var controlName in groups[groupName]) { // Find each control using Razor magic var control = base.FindPartialView(controllerContext, controlName, useCache); if (control.View != null) { controls.Add(control); } } if(controls.Count > 0) return new ViewEngineResult(new MyView(controls), this); } return base.FindView(controllerContext, viewName, masterName, useCache); } } </code></pre> MyView.cs: <pre><code>public class MyView : IView { IList<ViewEngineResult> controls; public MyView(IList<ViewEngineResult> _controls) { controls = _controls; } public void Render(ViewContext viewContext, TextWriter textWriter) { // For simplicity I used table for layout textWriter.Write("<table border='1'>"); foreach (var ctrl in controls) { textWriter.Write("<tr><td>"); // Render control using Razor ctrl.View.Render(viewContext, textWriter); textWriter.Write("</td></tr>"); } textWriter.Write("</table>"); } } </code></pre> Don't forget to register your new engine in Global.asax <code>ViewEngines.Engines.Add(new MyViewEngine());</code> Happy ending I can use this in two ways: embedded in a view using <code>Render.Partial</code> or just returning <code>PartialView</code> from my controller. Let me know if it helps you. And also you can share your solution.

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.
