For example, place the English version of a view in the Views/Home folder and the French version in Views/fr/Home. This property ensures that your views are compiled during the publishing process, reducing the startup overhead. The Razor syntax provides a concise and readable way to embed C# code within your HTML markup. It uses @ as a prefix to indicate code execution, variable interpolation, or control flow.
When embarking on a new ASP.NET Core project, getting the initial setup right is essential for a smooth development journey. The Razor engine does not have many of the features found in ASP.NET MVC. That means we can’t merely transplant our MVC views into a console application and hope it all works. We can register this instance with a dependency injection framework and share it throughout our application. The library has a static engine accessible through Engine.Razor, but we can also create an instance of the Razor engine for use in our applications. Let’s modify our code one more time to take advantage of a newly created Person class.

Razor view files are named to match controller action methods. For example, if you have an Index action in your HomeController, the corresponding view file should be named Index.cshtml. This naming convention helps ASP.NET Core automatically locate the correct view for a given action. Remember, a well-structured and organized project starts with setting up ASP.NET Core applications wisely.
- Create methods in your Page Model to handle Create, Read, Update, and Delete (CRUD) operations, leveraging the methods provided by Entity Framework Core.
- Fortunately, there are effective debugging and troubleshooting techniques to help you identify and resolve these problems.
- You can print @ in HTML by repeating (Escape) the @ symbol as shown below.
- Layout sections allow views to inject content into specific sections of a layout, adding flexibility and customization.
- The Views must have the power to process the info and generate a response.
- In this example, we’ve modified the view location formats to place views directly within the “Views” folder and its “Shared” subfolder.
It’s possible we want to use our own view instead of one that comes with Razor classlibrary. From Introduction to Razor Pages Razor Pages can make coding page-focused scenarios easier and more productive than using controllers and views. As far as Razor Page vs MVC approaches goes, Razor Pages essentially have no controller.
Leveraging Razor Page Conventions
Enhance user experience by implementing client-side validation. This provides immediate feedback on input forms before submitting data to the server. Configure the application to display custom error pages that provide a better user experience instead of the default https://remotemode.net/ technical error pages. They enforce rules like required fields, string lengths, and custom validation. When working with related data, you can include navigation properties in your models and use methods like Include and ThenInclude to fetch related records.
If you opted for Razor Pages, you’ll find a Pages folder that organizes your Razor Pages. Our results are exactly like the previous sample, but now we’re using our Person class to strongly-type our template. The Razor engine is able to process conditional statements like if and Switch statements.
Configuring Layout Sections for Dynamic Content
In this Razor tutorial, we will take a quick tour of the Razor View Engine in ASP.NET Core MVC. The Razor makes it easier to embed the C# code inside the HTML, thus providing the ability to generate the dynamic response. It starts with code block and its condition is written in parenthesis and the code which needs to be executed once condition razor engine .net core gets true is written inside braces. Razor is based
on ASP.NET, and designed
for creating web applications. It has the power of traditional ASP.NET markup,
but it is easier to use, and easier to learn. If needed we can override views but we have to be careful – views from Razor class library may contain logic we don’t know.
By
running on the server, the code can perform complex tasks, like accessing
databases. Razor Class Library is excellent way how to share web application components and UI artifacts. It’s not just about sharing components between projects in same solution – we can share our Razor class libraries as NuGet packages. The model seems flexible enough for me as it easy to take risks of overriding controllers, models, views and other components. I don’t give any suggestion right now about overriding as I am not yet sure what weight it actually puts to those responsible of Razor class libraries.
Understanding The Page Model
Use the AddModelError method to add validation errors to the ModelState. You can use conditions to process forms differently based on the input. This could include redirecting, re-displaying the form with an error, or sending a success message. The OnPost method in your Page Model handles form submissions.
As you embark on your journey with ASP.NET Core, understanding how the Razor View Engine operates out-of-the-box is essential. Let’s delve into the intricacies of its default behavior and grasp the conventions and settings that shape your view rendering experience. The library caches all template compilations using the template key parameter. Pranaya Rout has published more than 3,000 articles in his 11-year career.
