The OnPostAsync handler method calls the RedirectToPage helper method. The rendered HTML from Pages/Customers/Create.cshtml: Enter a customer name: In many cases, validation errors would be detected on the client, and never submitted to the server. If there are errors, show the page again with validation messages.If there are no errors, save the data and redirect.Most of the MVC primitives like model binding, validation, and action results work the same with Controllers and Razor Pages.

The OnPostAsync code in the preceding example looks similar to typical controller code.If you're familiar with ASP.NET apps using controllers and views: The preceding code is typical for Razor Pages. The Async naming suffix is optional but is often used by convention for asynchronous functions. In the preceding code, the OnGet method displays the CreateModel.cshtml Razor Page. OnGet to initialize state needed for the page.Handler methods for any HTTP verb can be added. The page has an OnPostAsync handler method, which runs on POST requests (when a user posts the form). Managing of page dependencies through dependency injection.It defines page handlers for requests sent to the page and the data used to render the page. The PageModel class allows separation of the logic of a page from its presentation. If (Customer != null) _(Customer) īy convention, the PageModel class is called Model and is in the same namespace as the page. Public CreateModel(Data.CustomerDbContext context) Private readonly Data.CustomerDbContext _context The Pages/Customers/ page model: public class CreateModel : PageModel The Pages/Customers/Create.cshtml view file: *, Public CustomerDbContext (DbContextOptions options) Public class CustomerDbContext : DbContext The db context: using Microsoft.EntityFrameworkCore Var builder = WebApplication.CreateBuilder(args) The in memory database requires the NuGet package. Consider a page that implements a basic "contact us" form for the Contact model:įor the samples in this document, the DbContext is initialized in the Startup.cs file. Model binding, Tag Helpers, and HTML helpers work with the properties defined in a Razor Page class. Razor Pages is designed to make common patterns used with web browsers easy to implement when building an app. Index is the default page when a URL doesn't include a page.
