An important feature of dynamic web pages is that you can determine what to
do based on conditions. 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. Data binding enables us to synchronize data between a component and a data store. The following view is located under /Pages/Index.cshtml. They exclude namespaces, as those may differ depending on the project name.
Keep in mind, a page is a component and each page in an app will likely contain multiple components. For more in-depth knowledge on the component lifecycle, visit Microsoft’s ASP.NET Core Razor component lifecycle documentation. 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. Redirecting is an essential part of web development, as it avoids the additional POST requests when we refresh a URL in our browser session. You can still choose to use ASP.NET Core MVC to build your ASP.NET Core web applications.
What are Razor Pages?
Then create a Bindable property called Id which also should support Get within the same EmployeeModel class as shown in the below image. Right-click on your project root directory and then add a new class file with the name Employees.cs and then copy and paste the following code into it. Once you click on the Add button, it will create asp net razor tutorial Employee.cshtml page within the Pages folder as shown in the below image. Once you add the above code within the _Layout.cshtml file, your code should look as shown below. The Get () verb takes an Id parameter and returns the First Name of the employee. To keep things simple, we are using the in-memory collection as the data source.
- The second line links the Razor page to a PageModel, IndexModel.
- ASP.NET web pages with Razor syntax have the special file extension cshtml
(Razor using C#) or vbhtml (Razor using VB).
- In this article, I am going to show you how to develop ASP.NET Core Razor Pages Application step-by-step with an example.
- Stream-based ZipFile methods enhance file handling without relying on disk storage.
- A source generator for options validation reduces startup time, and updated LoggerMessageAttribute constructors offer more logging flexibility.
- It has the power of traditional ASP.NET markup,
but it is easier to use, and easier to learn.
- The following code from the Message component (in Message.razor) renders the message.
We first start by creating a storage mechanism to hold our Name value. We are using TempData, which is a volatile storage mechanism provided 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.
If you are a seasoned developer, the Razor Pages framework is likely to add to your skillset with the minimum amount of effort. Part of the ASP.NET Core web development framework from Microsoft, Razor Pages supports cross platform development and can be deployed to Windows, Unix and Mac operating systems. This render mode is well suited for apps with complex client-side logic, allowing for a rich interactive user experience while leveraging client resources for rendering. The WebAssembly render mode operates by interactively rendering the component on the client with Blazor WebAssembly. The .NET runtime and the application’s bundle are fetched and cached at the initial rendering of the WebAssembly component. The Server render mode renders the component interactively from the server using Blazor Server.
Razor Pages is included within .NET Core from version 2.0 onwards, which is available as a free download as either an SDK (Software Development Kit) or a Runtime. The SDK includes the runtime and command line tools for creating .NET Core applications. The SDK is installed for you when you install Visual Studio 2017 Update 3 or later. The Runtime-only installation is intended for use on machines where no development takes place. Telerik UI for Blazor and Telerik UI for ASP.NET Core are set to fully support the upcoming .NET 9 framework, ensuring that developers can leverage the latest enhancements in their web projects. It is ideal for apps with interactive UIs but also needing server-side logic.
