asp.net core razor pages rerouting between three pages

Question

My problem is the following:   I have three pages, Index, Update and Form. I want to be able to redirecttopage from Index to Update or from Form to Update, do some actions on Update page and on Submit return to Index if I started from Index or to Form if I started from Form. How can I do this?

You can paas different parameters from pages to decide where it is coming from

public IActionResult OnPostRedirect2(int pageId)
{
if(pageId==1){
return RedirectToPage("Index3", "Welcome");
}
else{
return RedirectToPage("Index4", "Welcome");
}
}

I do this already Sachin, this is easy   public  IActionResult OnPostGasTesting( int  id)           {                return  RedirectToPage( "/PTW/GasTesting" ,  "PTWNoId" ,  new  { ptwNoId = id });                 }   I know how to redirecttopage, what I want is to access Update page from two different pages and after adding data in Update to return back to the page I came from, either Index or Form

sir

you can use return redirectToPage() after updating for example

public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseMvc();
}
}
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;
public IActionResult OnPostRedirect2()
{
return RedirectToPage("Index3", "Welcome");
}
