Back to previous page - mvc page Razor

Question

I’m trying to get back to the previous page this way:

string urlAnterior = Request.Headers["Referer"].ToString();

        if (urlAnterior.Contains("Pagina"))
            return RedirectToAction("");
        else
            return RedirectToAction("");

However it returns me to the current updated page, I need to go back to the previous page, how to proceed?

Code I use to call create inside people:

<div class="form-group">
  <a asp-page="/ContaReceber/Create" asp-route-id="@Request.Query[" id "]" class="btn btn-primary btn-sm">Criar nova Conta</a>
</div>

And this is where I call inside the Receivables Index:

<a asp-page="Create" class="btn btn-primary">Criar nova Conta</a>

Answer 1

try this way

or so

return Redirect(ControllerContext.HttpContext.Request.UrlReferrer.ToString());
return Redirect(Request.UrlReferrer.ToString());
return Redirect(HttpContext.Request.Headers["Referer"].ToString());

or so on the View side

<a href='javascript:history.go(-1)'>Go Back</a>
<a href="##" onClick="history.go(-1); return false;"> Go Back</a> 
<input type='button' onclick='history.go(-1);' value='Go Back' />
<input type="button" value="GO BACK" onclick="location.href='@Request.UrlReferrer'" />

@Html.ActionLink("Back to previous page", null, null, null, new { href = Request.UrlReferrer})

If Send url by parameter you can also use this way

public ActionResult FilterData(string redirectUrl = null)
{
    // Do some work
    // ....
    if (redirectUrl != null) {
        return this.Redirect(redirectUrl);
    }

    return View("Default");
}

You can do it like this

No control can also use so

if(Request.Headers["Referer"] != null)
{
    ViewData["Reffer"] = Request.Headers["Referer"].ToString();
}

E in the view (Razor)

@if(!string.IsNullOrWhiteSpace(ViewData["Reffer"]))
{
    <a href="@ViewData["Reffer"]">Return to client detail</a>
}

The RedirectToAction expects as argument a string with the name of the controller to which you want to redirect, as this blank, it redirects to the controller of the current method. Then you should put your controller name:

return RedirectToAction("SuaController");

or if you want to call the previous Url, do so:

return Redirect(urlAnterior);

I saw in your comments that you want to redirect to a page, based on the origin of the request that can be two, you can solve by changing your original code so:

string urlAnterior = Request.Headers["Referer"].ToString();

if (urlAnterior.Contains("Pessoa"))
    return RedirectToAction("Edit", "Pessoa");
else
    return RedirectToAction("Index", "ContaReceber");  

Changing controller and method names only.
