Injecting content into specific sections from a partial view ASP.NET MVC 3 with Razor View Engine. Optional Razor Sections with Default Content - Marcin On ASP.NET. Razor, Nested Layouts and Redefined Sections - Marcin On ASP.NET. In a recent post I introduced a technique for dealing with optional Razor sections and default content.
In this post I will expand upon that technique and describe a way of working with sections across nested layout hierarchies. If you are not familiar with sections, layout pages, or my technique then go ahead and read that post to catch up. One aspect of the relationship between layout pages and sections in Razor that a fair number of people might find surprising is that a section defined in a content page can only be used in its immediate layout. There is implicit scoping going on that prevents certain use cases. Take the following example: In the above example you can certainly call RenderSection("SubSection") in _MasterLayout.cshtml, as well as call RenderSection("ContentSection") in _SubLayout.cshtml.

Introduction In the last article, I explored Creating Custom HTML Helpers by creating a static method that returns a string.
In this article, I will explore HTML Helpers with Extension Methods. The HtmlHelper class provides a set of helper methods that generate plain HTML and return the result as a string. The extensions add helper methods for creating forms, rendering HTML controls and rendering partial views and they are located in the System.Web.Mvc.Html namespace. I will create a submit confirm button that renders an HTML <input type=”submit”> tag as SubmitConfirmHelper class shown below: using System.Web.Mvc; namespace Helpers { public static class SubmitConfirmHelper { public static string SubmitConfirm(this HtmlHelper helper, string buttonText, string alertMessage) { return String.Format( "<input type=\"submit\" value=\"{0}\" onClick=\"return confirm('{1}');\" />", buttonText, alertMessage); } } } Now you can run the project and it will render the form as shown below: Summary.
Telerik MVC : Extending the Telerik HTML Helper - ASP.NET Wiki. Written by John DeVight on 2011-May-18 Last Updated by John DeVight on 2013-Mar-15 Download TelerikBuilderExtensions.cs Last week I wrote a wiki page MVC 3 Razor : Creating Custom HTML Helpers about extending the HTML Helpers to be able to render controls read-only.
I also needed to extend the Telerik MVC controls to render the Telerik MVC controls read-only as well. I took a look at the Telerik.Web.Mvc.dll assembly using .NET Reflector and looked to see how Telerik extended the HTML Helper with their ViewComponentFactory, what we usually see as the Html.Telerik() method. The ViewComponentFactory creates an instance of a ViewComponentBuilder to "build" the control. Since I wanted to be able to render the Telerik controls as read-only, I overloaded the Render method to take a parameter of bool that indicates whether the control is editable or not. The class that derives from ViewComponentBuilder to render the DropDownList control is the DropDownListBuilder. TagBuilder Class to Build HTML Helpers (C# Stephen Walther introduces you to a useful utility class in the ASP.NET MVC framework named the TagBuilder class.
