As you can see, this brand new controller is a simple class which inherits from Controllerand contains only one method — Cree, which returns the View associated with this Action. Each Action can be associated with a View, without having to explicitly name the View as you could see, the Index method calls the View method without any parameters.

    This association is created by another instance of convention over configuration. Now go ahead and create the View. This is called markup syntax — the core of the magic of ASP. This is what allows you to create dynamic content and not just write static HTML pages. The default view tutorkal is called Razor and was designed for ASP. Different view engines may have different markup syntaxes for example, the classic ASP.

    For example, you may do the following:.

    As you could intuitively tell, the result of this simple markup block will be a list containing the numbers 0 to 9. Razor knows that a C for statement is beginning thanks to the character. It then searches for brackets that indicate a block of code is ahead. Had we not included this character, Razor would treat this as regular text.

    Code in markup sequences is your familiar C and. NET, and you may use whatever namespaces you like by adding a using statement at the top of the page — again, just like a regular class. You may also place breakpoints on Razor markup segments, which will be triggered at runtime. If you find yourself writing a lot of code in the View, double check yourself.

    The View should only contain code that renders the data from the Controller for textual representation. Code that interacts with the data, performs calls to external resources or can be even hypothetically reused outside the View, should always go in the Controller. Switch back to the Controller.

    In our Index method, just before we return the View, add the following line:. Now go ahead and press F5 to start debugging. This will launch an instance of your default browser, hosted on a local instance of IIS Express. Replace the with the random port number you see when the browser is launched.

    It worked! You can see bginners the routing is pretty intuitive — we went to the Person controller and then eownload the Index Action. This helps freee cleaner, search engine friendly URLs. Notice how our brand new View looks pretty nice without us doing any work? This is because of the Layout page. Most web applications have a consistent look throughout the website — same header, menu and footer, as well as additional items that we might want to make available site-wide.

    To do this in ASP. When you create a new View, Visual Studio will ask you if you want to associate it with a Layout page — by default this option is enabled.

    Open the Layout page. This is where each View will be rendered. In ASP. This is why the header we just added got a style which is different from the vanilla HTML style. We need to create a repository that will store the Persons in our application.

    We will store an instance of this data context as a private field inside our PersonController, and initialize it in the constructor. Now go ahead and populate this table with Persons you can easily do this by creating a Console Application project, referencing the current project, and adding Person objects to an instance of the PersonManagerDbContext, then calling context.

    So now we can easily access the Persons in our database by calling mDataContext. But how do we make this available to the View? One way would be using one of the shared objects — ViewBag or ViewData. We could add a Person property on the ViewBag and access it from the View. This approach has several problems associated with gor.

    To avoid this, we can make the model instance available tjtorial the View. To do this, open the Index view we worked on earlier, and add the following line in the top of the page:. You can then access the instance of this Model type by using the Model downlod.

    Notice that capitalization, as usual with Cmatters. Model with a capital M means a call to the instance downloadd the Model, and model represents the declaration similar to using.

    This is what the markup looks like:. Note the using statement for the Person class; this is different from the model statement, and is identical to a using statement we would use in a traditional class.

    But how would ASP. NET know which Action to access in every use case? Thanks to the [HttpGet] and [HttpPost] attributes.
