Configure routing for controller actions

With Sitefinity CMS, you can work with attribute routing in the context of Sitefinity CMS widgets. As a result of the integration with ASP.NET MVC 5, you can use the RelativeRoute attribute to work with attribute routing and attributes to define routes for controller actions.

NOTE: When using the RelativeRoute attribute on one of the controllers actions, all controller actions must be decorated with the attribute, as well. 

The RelativeRoute attribute has the same constructors and properties as the stock Route attribute. Sitefinity CMS automatically maps all routes defined, using the attributes for both RelativeRoute and Route attributes. As a result, you do not need to call the MapMvcAttributeRoutes.

The Route attribute, describes routes relative to the application path. The RelativeRoute attribute, on the other hand, describes routes relative to the page node where the widget is placed.

This example illustrates the difference between the two attributes. You have the following widget implementation:

If you add this widget to a page with an URL ~/my-page, then you get two routes:

• ~/my-page/my-sample-path
  Displays the page and renders "This is Action1" on the place where the widget is located on the page.
• ~/my-sample-path
  Renders "This is Action2" as plain text.

NOTE: If there are any RelativeRoute attributes on your controller, then the default Sitefinity CMS autorouting handling and the convention-based routes are ignored.
