What are surface controllers?
A surface controller is basically an MVC controller that interacts with the frontend rendering of your Umbraco page.
They can be used for many things, like Child actions content, and are most commonly used to handle data from form submissions.
That is also what we will be using the surface controller for in this chapter; for handling the data that is submitted via a form on our website.
Benefits of using and working with surface controllers
When you are working with surface controllers you will also benefit from the native Umbraco support for interacting with routes during HTTP POST requests, for rendering forms, and for rendering ASP.NET MVC child actions.
Surface controllers in this chapter
In this chapter, you will be using the surface controller to handle data from a submission form on your website. The data needs to be mapped to a set of properties on a Document Type and added to a new piece of content. Finally, you will use the controller to ensure that the data is rendered using the correct view.
Check out the resources below to learn more about MVC and MVC in Umbraco.
Download the template project, if you want to follow along with the exact steps throughout this chapter.
Template project and ModelsBuilder
In the template project, the ModelBuilder is enabled. The project is configured to use the `LiveAppData` ModelBuilder mode.
The project is also configured to store all PublishedModels - the models generated automatically by Umbraco, in a folder called "PublishedModels".
If you're using your own project to run through this chapter, make sure to use the same or similar ModelsBuilder configuration.
