ASP.net Redirect to the calling page

Question

I have a page that calls another page with some query string parameters. I want to return back to that page after clicking on a button.

I have to mention that I write that code in a user control and I don't know what page called that second page.

Is there something like Back button in browsers?

You could look at Cross Page Posting.

Alternatively, if you are generating the link programatically you could include the returnUrl in the url e.g. http://localhost/secondpage.aspx?returnurl=firstpage.aspx

You can then read this querystring parameter in the secondpage and perform as redirect back once your work is done.

Simplest way use javascript on client side with

window.back();

For server side you need to save the url referer in page_load:

if(!Page.IsPostback)
{
  ViewState["GoBackTo"] = Request.UrlReferrer;
}

and on a button click using Response.Redirect:

Response.Redirect( ViewState["GoBackTo"].ToString() );

You can use the Request.UrlReferrer, but it is not necessarily sent from the client all the time:

        Response.Redirect(Request.UrlReferrer.AbsoluteUri);

Solution 4

put this line of code on the page load event

 Btn_Back.Attributes.Add("onClick", "javascript:history.back(); return false;");

the UrlReferrer is not work all the time, how ever this is a better way than the robert.

No it wont always work if they come direct to the page. Just catch it out like if (ViewState["GoBackTo"] == null) and if there is null just redirect to the default login page like account.aspx or similar. This is nice if you do not want to use forms authentications +1
