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?

Answer 1

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.
