Blazor’s Razor Components are at the heart of Blazor development. A component is a piece of a user interface with processing asp net razor tutorial logic to enable dynamic behavior. ASP.NET helpers are components that can be accessed by single lines of
Razor code.
This alignment allows developers to immediately utilize the advanced capabilities and performance benefits of .NET 8, while continuing to enjoy the rich set of UI components Progress Telerik provides. Let’s explore some of the key .NET 8 new features together. You can build and run the application with default contents or let open the Index.cshtml file and put some contents there. With these events you can manage the lifecycle of a component as needed. Note that some events are only raised upon the first time a client accesses a page. Additionally, there is a workflow to how components are rendered.
Explain how Razor Pages work in ASP.NET Core
Server code can create dynamic HTML content on the fly, before it is
sent to the browser. Seen from the browser, the HTML generated by server code is
no different than static HTML content. It’s no secret in software development that components enable modular development and promote code reuse since each component is a discrete unit of code and markup. In Blazor, components are controlled through lifecycle events, where you can retrieve data and render displays. If you choose to build your own, you can choose from a wide range of programming languages and frameworks.
As a result, the component is statically rendered server-side. When the server reads the page, it runs the Razor code first, before it sends
the HTML page to the browser. The code that is executed on the server can
perform tasks that cannot be done in the browser, for example accessing a server
database.

MessageText is the parameter, so at runtime «An error has occurred» is passed to the Message component for display. Two-way data binding means that the DOM element that is data bound participates in the HTTP POST request when data is sent to an API. Two-way data binding is done by using the @bind or @bind-Value attributes in an element.
- In general, it’s better to use async operations for scalability and a smoother responding UI.
- The following view is located under /Pages/Index.cshtml.
- We can start with the ASP.NET Razor Pages template installed with .NET.
- Note that some events are only raised upon the first time a client accesses a page.
- MessageText is the parameter, so at runtime «An error has occurred» is passed to the Message component for display.
This mode handles user interactions over a real-time connection with the browser, and the circuit connection is established when the Server component is first rendered. Static render mode is the default setting for all components, which results in the component being rendered to the response stream, and does not enable interactivity. A PageModel class is the «code-behind» for a Razor Page that performs the actual heavy lifting, e.g., processing business logic, making external requests, fetching data from the database, etc. All Page Model classes derive from the PageModel base class. They also provide one or more page handers, which are simply methods that define how to handle requests to the Razor Page.
