What does OnGetRedirectToPage do? ASP.NET Core Razor Pages

Question

Hello,

What does OnGetRedirectToPage do?

I expected this method to redirect the Test to the Privacy page. But it didn't do anything.

@page
@model Web_6.Pages.TestModel
@{
}

<h2>In Test</h2>

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace Web_6.Pages
{
     public class TestModel : PageModel
     {
          //public IActionResult OnGet()
          //{
          //     return RedirectToPage("/Privacy");
          //}
          public IActionResult OnGetRedirectToPage() 
               // It doesn't redirect to Privacy and still in Test page.
          {
               return RedirectToPage("/Privacy");
          }
     }
}

Most likely the OnGetRedirectToPage() handler is not executing. You did not share how TestModel is called Assuming TestModel is in the root, the URL would be...

<a href=/Test?handler=RedirectToPage>Call Redirect</a>

    public class TestModel : PageModel
    {
        public void OnGet()
        {
        }

        public IActionResult OnGetRedirectToPage()
        {
            return RedirectToPage("/Privacy");
        }
    }

@page
@model RazorPagesDemo.Pages.TestModel
<a asp-page-handler="RedirectToPage">Redirect</a>

Try the following

public class IndexModel : PageModel
{
    public IActionResult OnGet() => new RedirectToPageResult("/Privacy");
}

Hi @Shervan360,

In Razor Page, The action name is composed of two parts. The first part is On + http verb and the second part is the real name of this action. For example, Your action name is OnGetRedirectToPage, It just like the below method in normal mvc project:

[HttpGet]
public IActionResult RedirectToPage(){...}

In your project, The default OnGet() is for rendering the page, If you want to redirect via OnGetRedirectToPage action, You need to call this action in Test page. Because OnGetRedirectToPage is a HttpGet method, So you can just use <a></a> to call it. Use asp-page-handler taghelper to sepecify the real name of the target action,

<a asp-page-handler="RedirectToPage">redirect</a>

After you click this <a> tag, OnGetRedirectToPage will be called, Then return RedirectToPage("Privacy"); will rediret to the page successfully.
