ASP.NET MVC 4 - Redirect to the same page after controller ends

Question

From a page I have the following:

@using (Html.BeginForm("AddEntry", "Configure", FormMethod.Get, new { returnUrl = this.Request.RawUrl }))
{
    @Html.TextBox("IP")
    @Html.Hidden("TypeId", 1)
    <input type="submit" value="@Resource.ButtonTitleAddComponent" />
}

so controller is called correctly:

public ActionResult AddEntry(string ip, int TypeId, string returnUrl)
{
    // Do some stuff

    return Redirect(returnUrl);
}

My problem is that returnUrl gets null and it does not redirect to the same page that called the controller. Ideas?

Using: ASP.NET MVC 4 Razor

Answer 1

you can also do this if you need to return to something like details page and return to the same page with a query:

return Redirect(Request.UrlReferrer.PathAndQuery);

Answer 2

You can get the Refer URL from the Request in the controller:

public ActionResult AddEntry(string ip, int TypeId, string returnUrl)
{

     // Do some stuff
     string url = this.Request.UrlReferrer.AbsolutePath;

     return Redirect(url);
}

This will redirect you exactly to the calling URL.

Answer 3

You could use a Request.QueryString method to get some values from URL, for sample:

@using (Html.BeginForm("AddEntry", "Configure", FormMethod.Get, null))
{
    @Html.TextBox("ip")
    @Html.Hidden("TypeId", 1)
    @Html.Hidden("returnUrl", this.Request.RawUrl)
    <input type="submit" value="@Resource.ButtonTitleAddComponent" />
}

And in your controller, receive it as a parameter string returnUrl.

Answer 4

in your controller class use Request.UrlReferrer. There's no need to pass the url from the page.

   public ActionResult AddEntry(string ip, int TypeId)
    {

         // Do some stuff

         return Redirect(Request.UrlReferrer.ToString());
    }
