how to be redirected to the previous page using response.redirect() in asp.net c#

Question

Right now i have a folder with another folder inside of it. The two folder names are called "pc details" and "pchardwaredetails"

When on a page in "pchardwaredetails" i want to return to a page in "pc details" using a button and response.redirect() but the file paths are just getting too complicated for me. What might the file path be from a page called "Details" in "pchardwaredetails" to a page called "viewMore" in "pc details"?

Also please feel free to explain how paths work so i know for future

thanks

Answer 1

Usually the Referrer of the page (a HTTP header), tells you what page you've come from so to go back you should just be able to do:

Response.Redirect(Request.UrlReferrer.ToString());

That's assuming you came from PC Details. However if you land on PC Hardware Details from some other page then that won't work, you would have to hard code the back feature.

You can simplify ASP.NET paths and use ~, for example:

Response.Redirect("~/some/path/pc_details.aspx");
