Passing data from get or post handler method to asp.net core razor pages in Visual Studio 2022

Requirement: Visual studio 2022
Objectives: How to pass data from OnGet or OnPost handler methods to Razor Pages
1. Using PageModel Properties (most common)

2. Using TempData (Good for Redirects)
3. Using ViewData or ViewBag (per request only)
4. Binding Form Data on POST


Benefits of asp-for:
asp-for is an attribute used in ASP.NET Core Razor Pages (and also in MVC) as part of Tag Helpers.

It binds an HTML form element to a model property, making it easier and more type-safe to generate form fields.

It tells Razor to generate the appropriate name, id, and sometimes value attributes for an HTML element, based on a property in your model.

Strongly typed: Refactoring-safe (e.g., renaming a property will update everywhere).

Cleaner HTML: Less manual wiring of attributes.

Automatic validation: Works with asp-validation-for to display model validation errors.
