An Introduction To ASP NET Razor Pages
If you are porting an existing .NET Framework MVC application to .NET Core, it may well be quicker or easier to keep with the MVC framework. However, Razor Pages removes a lot of the unnecessary ceremony that comes with the ASP.NET implementation of MVC and is a simpler, and therefore more maintainable development experience. Assuming the request is valid, the application model will return the required details to the page handler. It’s then up to the page handler to choose a response to generate.
MVC also takes care of live-reloading Razor Views behind-the-scenes so we’re also able to get the same iterative development experience we’re used to. By using MVC Views we also naturally get good tooling support which can be a dark art in .NET 4.5 which was tightly coupled to Web.config configuration and therefore poorly supported in Self-Hosting Console Apps. Razor Pages can also be used to make things other than web pages, like APIs and microservices. (Remember when Microsoft said ASP.NET is good for web apps AND services?) In those cases we wouldn’t need a view page, we’d just use page models. Razor is a template language used by ASP.NET Web Pages, ASP.NET MVC , and ASP.NET Core.

All Telerik UI for ASP.NET Core components are compatible with the ASP.NET Razor Pages framework. The following example demonstrates how to add a Grid to a Razor page and configure its CRUD operations. The @page directive placed at the top of the page makes it a Razor Page. The page contains both HTML and server-side logic, which you include by using Razor syntax. I am not sure why the ModelState validity checks keep returning false, hence preventing a write to DB action, even though values supplied to all the properties are of right DataType and successfully … Advertise with TechnologyAdvice on CodeGuru and our other developer-focused platforms.

Only employees will be ableto use the system, though at some point in the future they want to develop … I just wanted to ask if it is possible to save a boolean to see if a user is currently logged in WITHOUT a cookie? I read about Identity in ASP.NET, but how does it save the whole data? They exclude namespaces, as those may differ depending on the project name.

- The Razor syntax is a template markup syntax, based on the C# programming language, that enables the programmer to use an HTML construction workflow.
- Razor was in development in June 2010 and was released for Microsoft Visual Studio 2010 in January 2011.

It has additional features, such as the filter pipeline, and more advanced behavior around binding models, but the overall behavior of the system is the same. A few months later, someone new started working on the app, and immediately “helped” by renaming an innocuous spelling error in a class in the business layer. Unfortunately, the names of those classes had been used to generate our HTML code, https://remotemode.net/ so renaming the class caused the whole website to break in users’ browsers! Suffice it to say, we made a concerted effort to apply the MVC pattern after that, and ensure we had a proper separation of concerns. The application model is responsible only for executing the required business logic. This binding model in this case corresponds to the method parameter of the OnGet page handler.

ASP.NET Core Razor Pages in Action teaches you to develop dynamic websites using the powerful Razor Pages framework, .NET 6, and ASP.NET. Razor Pages generates HTML on the server, and is the perfect choice for eCommerce sites, intranet services, content management systems, and other apps that require reliability. In this book, you’ll use Razor Pages to build a complete application for booking city breaks, learning to iterate amazing new features chapter-by-chapter. You’ll even learn how to enhance your web applications with the huge ecosystem of C# libraries, and how to locate the perfect tool for your task using centralized repositories. A request to the `/category/Simple` URL results in the `CategoryModel.OnGet` page handler being executed, passing in a populated binding model, category. In this case, the binding model is a simple string, category, which is “bound” to the “Simple” value. A more complex binding model could also have been used, where multiple properties were populated.
- I showed how to specify the cultures that the application supports, how to set the culture for the current request, and how some items, such as calendars are translated depending on the current culture.
- A view model captures the details necessary for the view to generate a response.
- The vast majority of examples out there feature the convention-based approach.
- The razor pages project looks quite similar to ASP.NET Core MVC project, except there is no Model – View – Controller folders, instead a new Pages folder added.
- Since we start with an empty application and don’t even have a single controller, let’s add a HomeController.
We first start by creating a storage mechanism to hold our Name value. We are using TempData, which is a volatile storage mechanism provided how to become a .net razor developer by ASP.NET. Any data stored in TempData will only exist from the time of our incoming request to the time we return a response.
