ASP NET Razor Markup

The second line links the Razor page to a PageModel, IndexModel. Next, inside the @ block, we have C# code that executes without writing any HTML to the response. We can also have dynamic C# code to render HTML and plain old static HTML inside a Razor Page.

• The important thing that Razor Pages accomplish is that they separate the view generation logic from the actual data computation or business logic.
• This follows the separation-of-concerns principle and keeps the application maintainable.
• If you have a Razor Page located inside Pages/Admin/Login.cshtml then you can access it using the following URL.
• Another important feature of dynamic web pages is that you can read user
  input.
• If you want client-side validation on several pages in your web application, then implement the scripts using the Layout file else implement them on the specified razor pages.
• The Razor syntax gives you all the power of ASP.NET, but is using a simplified
  syntax that’s easier to learn if you’re a beginner, and makes you more
  productive if you’re an expert.
• If you’re creating a new app using Razor, I strongly suggest considering Razor Pages as the default approach.

In validation, we will look at the client-side validation of the razor pages. EzzyLearning.net is an online tutorial website to learn about ASP.NET Core, ASP.NET MVC, AngularJS, C#, VB.NET, AJAX, JQuery, WCF, LINQ, Android, Java and more. Last but not least, you also have to register the services needed for Razor https://remotemode.net/ Pages in your Startup.cs file using AddRazorPages method. If you have a Razor Page located inside Pages/Admin/Login.cshtml then you can access it using the following URL. Another important line in your Razor Page is the @page directive which specifies that this View is not a normal Razor View, it’s a Razor Page.

Razor Syntax

Another common practice you may have noticed in MVC applications is a grouping of similar actions in almost all of your controllers. The number of these actions also increases as your applications grow and I have seen examples where people have almost 100+ actions inside a single controller. If you choose to build your own, you can choose from a wide range of programming languages and frameworks. If you are a beginner, you will probably want to start with a framework and language that is easy to learn, well supported and robust. If you are considering making a career as a programmer, you probably want to know that the skills you acquire while learning your new framework will enhance your value to potential employers. In both cases, learning C# as a language and ASP.NET Core as a framework will tick those boxes.

If you have been looking for a better and simpler way to create a razor pages web app, using ASP.NET Core would be the best for you. This focuses on how one could come up with a working razor page web app. If you have too many properties in your model then you may use [BindProperties] attribute on your entire class rather than specifying [BindProperty] with each property. Once the router has selected the Razor Page, the framework executes that Razor Page to generate the final HTML response. This response then makes its way back to the client browser that made the request.

Advantages of Razor Pages

These actions are also highly coupled in the sense that most of the time they require similar initialization logic, same View Model, and even the same Razor View. If you have worked with ASP.NET MVC controllers, then you may already know those action methods in MVC controllers have built-in data binding mechanism. The parameters of an action method are automatically bound with the query string or request parameters of incoming requests.

• These actions are also highly coupled in the sense that most of the time they require similar initialization logic, same View Model, and even the same Razor View.
• Our next step is to implement our OnPost method, which will process our incoming form data, and assign it to our TempData property.
• Razor syntax is based on the ASP.NET framework, the part of the Microsoft.NET Framework that’s specifically designed for creating web
  applications.
• You can easily see in the above AccountController that a single page e.g.

A corresponding Page Model class will also be generated for you. You will be asked to provide a name with some other options that will allow you to generate a Page Model (code behind) class with your page, specify the Layout of your page, etc. They exclude namespaces, as those may differ depending on the project name.

Under the hood, Razor Pages use the same routing infrastructure that is used by MVC but there are few differences related to configuration. For MVC and Web API applications, we have convention-based routing that means the incoming URL will be matched directly with controllers and actions. For example, the URL /Products/Index will match with the following action method of the Products controller in MVC. Razor Pages are physical .cshtml files and to create Razor Page you need to create a Pages folder inside your project. This is by convention but if you want to create a folder with some other name then you have to tell ASP.NET where the Razor Pages are located.

Ideal candidates can be About Us, Contact Us, and Site Map pages. If you are not a big fan of mixing HTML and C# in a single file or your page logic is becoming more complex, then you are also allowed to put your C# code in a separate file attached to Razor Page. This is an almost similar idea as we had in ASP.NET Web Forms in the past where we were adding all the C# code in a code-behind asp net razor tutorial file. Microsoft introduced a new programming model in ASP.NET Core 2.0 called Razor Pages that reduced all this ceremony and simplified the process of implementing page focus scenarios. In this tutorial, I will cover the Razor Pages in detail and hopefully, if you will follow along with me, you will be able to use Razor Pages in your applications with more confidence.
