A default layout is set up for your application in the _Layout.cshtml file located in Pages/Shared/. A database record
might have a FirstName and a LastName property (among others). This course will teach you https://remotemode.net/ how to build modern web applications using Razor Pages. You’ll learn how to implement common design patterns, build pages and layouts, work with forms and data, configure and deploy apps, and much more.

  • Security issues and bugs should be reported privately, via email, to the Microsoft Security Response Center (MSRC) You should receive a response within 24 hours.
  • If you are porting an existing .NET Framework MVC application (MVC5 or earlier) to .NET Core, it may well be quicker or easier to keep with the MVC framework.

By specifying the model in the view page, Razor exposes a Model property for accessing the model passed to the view page.

Redirecting is an essential part of web development, as it avoids the additional POST requests when we refresh a URL in our browser session. If there is server code in the web page, server executes that code first then send response to the browser. Razor Pages have layouts, base templates that define the common elements of the application, such as headers and footers. asp net razor tutorial This layout HTML is added to the Razor Page HTML to generate the complete HTML response, preventing duplicate code.

Basics of Razor Pages

Once the application receives an HTTP request, it moves through the middleware pipeline until it reaches a middleware component that can handle and process it. Typically, it’s a routing middleware that matches a URL path to a configured route. This route defines which Razor page to invoke for this particular request. ViewData is a dictionary that can contain key-value pairs where each key must be a string. In Razor Pages, you can use the ViewData property to pass data from a Page Model to its corresponding view page, as well as share it with the layout, and any partial views.

Razor Syntax allows you to embed code (C#) into page views through the use of a few keywords (such as “@”), and then have the C# code be processed and converted at runtime to HTML. Our next step is to implement our OnPost method, which will process our incoming form data, and assign it to our TempData property. After storage, we want to redirect the page to the OnGet handler of our page.
