Executing an Umbraco request
During the Umbraco request execution, an MVC Action is called which executes a Razor view to render content to the end-user,
Using the Model
Whenever a content item is rendered on the front-end, it is based on a model of type
This model contains all of the information about the content item associated with the current request.
If you are working in a custom MVC Controller's action, a model of type
ContentModel will be provided in the Action's method parameters.
This model contains an instance of
IPublishedContent which you can use.
When you are working in a View of type
UmbracoViewPage (which is the default view type), the Model provided to that view
IPublishedContent. For example, to render the current content model's name you could do:
All Umbraco view page types inherit from
UmbracoViewPage<TModel>. A neat trick is that if you want your view Model to be
you can change your view type to
UmbracoViewPage and the view will still render without issue even though the controller
is passing it a model of type ContentModel.
IPublishedContent is the standard model used for all published content, media and members in Umbraco. It is a strongly typed model and is very flexible.
UmbracoHelper is the unified way to work with published content/media on your website. Whether you are using MVC or WebForms you will be able to use UmbracoHelper to query/traverse Umbraco published data.
MembershipHelper is a general helper class for accessing ASP.NET membership data, as well as Umbraco Member data, which are stored in a format similar to Umbraco content and media.
