ASP.NET Core Razor Pages handles multiple submit buttons by defining separate handler methods within the PageModel class and using asp-page-handler tag helpers in the view to route each button to its corresponding C# method.

The best way to structure PageModel classes for complex data editing is to separate input models, apply validation attributes, and use view components for reusable UI logic. This maintains clean server-rendered web application architecture.

To validate input models in Razor Pages, apply data annotation attributes to your C# properties. The framework automatically checks these constraints upon form submission, enabling server-side validation for your web application.

Use view components in ASP.NET Core when you need reusable UI elements with complex logic or data retrieval, whereas partial views are better suited for simple markup reuse without requiring separate server-side logic processing.

Yes, ASP.NET Core Razor Pages supports anti-forgery token implementation automatically. The framework generates and validates these tokens by default on form submissions to secure your server-rendered web applications from cross-site request forgery.
