ASP.NET MVC 3 introdues a new view-engine option called “Razor” which enables you to quickly integrate server code into your HTML markup with a minimum of keystrokes. Unlike most template syntaxes, you do not need to interrupt your coding to explicitly denote server blocks within your HTML. This enables a really compact and expressive syntax which is clean, fast and fun to type. Here are the quick view related to Razor view-engine in asp.net MVC 3.0.
| File Extension | .cshtml for c# and vbhtml for vb.net |
| _(underscore) | Files that cannot be shown by direct requests (master pages, partial views etc) have underscore (_) prefix in their names. e.g. _Layout.cshtml |
| @ | start of a server side code block. It doesn't require you to explicitly close the code-block. (short-hand of <%= %>) |
| @{ code } | (Multi-line Statements) add multiple lines of server side code by wrapping it within a @{ code } block. |
| @( ) | (Multi-Token Statements) enables a code block to have multiple tokens |
| @: | to explicitly indicate the start of content in the line |
| <text> | to render multi-line content blocks |
| layout page | asp.net master page is recognized in MVC |
| Layout <file> | layout we want to use within a ASP.NET MVC |
| @* comment *@ | To define server side comment (like <%-- --%>) ) |
| @RenderBody | used in layout where we want the views based on this layout to “fill in” specific body content for a requested URL. |
| @RenderSection | define two sections within our layout that the view templates within our site can optionally choose to fill-in |
| @section { } | To define section |
| @model <StrongModelType> | define strongly-typed models |
| @ViewBag.<myData> | New Dynamic Controller property, It internally stores the property name/value pairs within the ViewData dictionary. It is used to pass Data Between a Controller and a View |
| @tempdata | To pass State Between Action Methods |
| Standard HTML Helpers(not a complete list) | * Html.ActionLink() * Html.BeginForm() * Html.CheckBox() * Html.DropDownList() * Html.EndForm() * Html.Hidden() * Html.ListBox() * Html.Password() * Html.RadioButton() * Html.TextArea() * Html.TextBox() |
